How to install a vacuum pump
A vacuum pump creates a relative vacuum within a sealed volume by drawing gas molecules from the sealed volume. Vacuum pumps can be used in a variety of industrial applications. They also offer various lubrication options. If you are considering purchasing, please understand its functions and features before purchasing.
How it works
The working principle of a vacuum pump is called gas transfer. The principle can be further divided into two basic categories: positive displacement and momentum transfer. At high pressure and moderate vacuum, gas molecules collide and move and create a viscous flow. At higher vacuum levels, gas molecules separate to create molecular or transitional flows.
Another principle of vacuum pumps is fluid-tightness. There are two main types of seals: rotary seals and screw seals. Rotary seals prevent liquid leakage, while screw seals only allow liquids to flow out at higher pressures. Some pumps may not use the third seal.
The flow rate of the vacuum pump determines the machine’s ability to pump a certain amount of material. A higher pumping speed will shorten the drain time. Therefore, the mass flow of the vacuum pump must be carefully considered. The speed and type of vacuum must also be considered.
The working principle of a vacuum pump is to push gas molecules from a high-pressure state to a low-pressure state. This creates a partial vacuum. There are many different types of vacuum pumps, each with different functions. Some are mechanical, some are chemical. In either case, their function is the same: to create a partial or complete vacuum. Vacuum pumps use a variety of technologies and are sized according to the application. Proper sizing is critical for optimum efficiency.
Gas transfer pumps use the same principles as vacuum pumps but use different technology. One of the earliest examples is the Archimedes spiral. Its structure consists of a single screw inside a hollow cylinder. More modern designs use double or triple screws. The rotation of the screw causes gas molecules to be trapped in the cavity between the screw and the housing. The fluid is then discharged at slightly above atmospheric pressure. This difference is called the compression ratio.
Another type of vacuum pump is a diffusion pump. Its main use is industrial vacuum processing. It is used in applications such as mass spectrometry, nanotechnology and analytical instrumentation. These pumps are generally inexpensive to purchase and operate.
Apply
Vacuum pumps are essential for many scientific and industrial processes. They are used in the production of vacuum tubes, CRTs, lamps and semiconductor processing. They can also be used to support mechanical equipment. For example, they can be mounted on the engine of a motor vehicle. Likewise, they can be used to power hydraulic components of aircraft. Among other uses, the vacuum pump helps calibrate the gyroscope.
Vacuum pumps are widely used in the pharmaceutical industry and are one of the largest users of this technology. They help deal with hazardous materials and eliminate waste quickly. They are also used in power jets, dump fuel tanks and rear doors, among others. However, they are sensitive to contamination and should only be used in environments where leaks can be prevented. Therefore, choosing the right fluid for the application is very important.
The most popular type of vacuum pump is the rotary vane pump. These pumps are known for their high pumping speed and low pressure. Their efficient pumping capacity allows them to reach pressures below 10-6 bar. Additionally, they are usually oil-sealed and have excellent vacuuming capabilities.
Vacuum pumps are often used to remove air from closed systems. They create a vacuum by reducing the density of the air in the compressed space. This is done by using the mechanical force energy generated by the rotating shaft. When the pump is under pressure, it converts this energy into pneumatic power. When the pressure is different, the energy produced depends on the volume of the gas and the pressure difference between the inner and outer atmospheres.
Vacuum pumps are also used in the manufacture of solar cells. They are used in the manufacture of solar cells, including ingot casting processes as well as cell and module processes. The design of the vacuum system plays an important role in reducing the cost of the process, thus making it profitable. Due to their low maintenance costs, they are an invaluable tool for making solar cells.
Vacuum pumps are widely used in many applications. In addition to industrial and research uses, they are also used in water remediation. 
Oil Lubrication Option
Vacuum pumps are available in a variety of oil lubrication options. Choosing the right lubricant can help protect your vacuum pump and maximize its performance. Different base oils may contain different additives, such as antioxidants, and some contain additional additives for specific purposes. You should choose an oil with the right concentration of these additives for optimal lubrication of your vacuum pump.
Vacuum pumps are usually lubricated with paraffinic mineral oil. However, this type of lubricant evaporates as the temperature increases. To minimize evaporative losses, choose a lubricant with low vapor pressure. Also, you should choose lubricants that are resistant to extreme temperatures. Extreme temperatures can put extra stress on the oil and can even significantly shorten the life of the oil.
In terms of viscosity, synthetic oils are the best choice for vacuum pumps. These types of oils are designed to resist gas dissolution and are more resistant to corrosion. Therefore, synthetic oils are ideal for handling aggressive substances. Whether or not your pump needs lubrication, choosing a quality product is important.
The vacuum pump oil should be changed periodically according to the manufacturer’s recommendations. If you use a filter, you should also change the oil as soon as the filter reaches the end of its life. Unplanned oil changes will eventually cause the vacuum pump to not reach its maximum vacuum capacity.
You can buy vacuum pump oil from vacuum pump manufacturers or other suppliers. These options are available in a variety of sizes, and labels can be customized. The oil should be designed for the pump. However, you should check the manufacturer’s recommendations to avoid buying the wrong type.
If you choose to use a synthetic oil, it is important to use a good quality oil. It helps the pump work more efficiently and prolong its life. 
Install
After choosing a suitable location, the next step is to install the pump. First, place the pump on a flat surface. Then, screw the pump onto the motor body above the check valve. Make sure the accessories are wrapped with sealing tape and secured with screws. The direction of gas inflow and outflow is indicated by arrows on the pump. The direction of rotation around the pump is also shown.
During commissioning, check the operation of each part of the pump. If the pump is equipped with a pipe connection, the pipe should be the same size and shape as the pump flange. Also, make sure that the piping does not cause any pressure drop. In addition, the first three weeks of operation require the installation of protective nets at the suction ports.
When selecting a pump, consider the back pressure of the system. Too much back pressure will affect the capacity of the vacuum pump. Also, check the temperature of the seal. If the temperature is too high, the seal may be damaged. It could also be due to a partially closed valve in the recirculation line or a clogged filter. Circulation pumps and heat exchangers should also be checked for fouling.
The vacuum pump is usually installed in the chassis area of the car. They can be mounted next to the engine or on a lower support frame. They are usually fastened to the bracket using suitable shock absorbers and isolating elements. However, before installing the vacuum pump, be sure to check the vacuum pump’s wiring harness before connecting it to the vehicle.
In many experimental setups, a vacuum pump is essential. However, improperly installed vacuum pumps can expose users to harmful vapors and chemicals. Appropriate plugs and belt guards should be installed to prevent any accidental chemical exposure. It is also important to install a fume hood for the pump.
In most cases, vacuum pumps come with installation manuals and instructions. Some manufacturers even offer start-up assistance if needed.

– Compatibility with Impregnating Substances: Roots vacuum pumps are compatible with a wide range of impregnating substances, including resins, oils, solvents, and other liquids. They can handle different chemical compositions and provide a clean and efficient environment for the impregnation process.
4. Considerations for Vacuum Impregnation:
– Material Compatibility: It is essential to consider the compatibility of the porous material with the impregnating substance and the impregnation process itself. Some materials may require pre-treatment or surface preparation before impregnation. The choice of impregnating substance should also align with the material’s properties and intended application.
– Process Parameters: Vacuum impregnation involves controlling various process parameters, such as vacuum level, impregnation time, pressure release, and curing conditions. These parameters may vary depending on the material, impregnating substance, and desired impregnation results. Proper process optimization and control are crucial for achieving consistent and reliable impregnation outcomes.
– System Design: The design of the vacuum impregnation system should consider factors such as chamber size, gas flow rates, vacuum pump capacity, and pressure control mechanisms. Proper system design ensures efficient operation, reliable vacuum conditions, and effective impregnation of the porous material.
In summary, Roots vacuum pumps are well-suited for vacuum impregnation in manufacturing. Their high pumping speed, large volume handling capability, continuous operation, and compatibility with impregnating substances make them effective in creating and maintaining the required vacuum conditions for successful impregnation. By considering material compatibility, process parameters, and system design, Roots vacuum pumps contribute to the efficient and reliable impregnation of porous materials in various manufacturing applications.
What Is a Roots Vacuum Pump, and How Does It Work?
A Roots vacuum pump, also known as a Roots blower or a rotary lobe pump, is a type of positive displacement vacuum pump that is widely used for various industrial applications. Here’s a detailed explanation of what a Roots vacuum pump is and how it works:
A Roots vacuum pump consists of two synchronized rotors, known as lobes or impellers, that rotate in opposite directions within a housing. The lobes have a unique helical shape with multiple lobes, which allows them to trap and move gas efficiently. The rotors are synchronized with the help of timing gears to maintain precise clearances between the lobes and the housing.
The operation of a Roots vacuum pump can be described in the following steps:
1. Inlet Stage: The process begins with the lobes rotating in opposite directions. As the lobes rotate, the volume between them and the housing gradually increases, creating a larger space at the inlet side of the pump. This expansion of the volume causes the gas to enter the pump through the inlet port. The gas is drawn in due to the pressure difference between the inlet and the pump’s internal chamber.
2. Compression Stage: As the gas enters the pump, it gets trapped in the spaces between the lobes and the housing. As the lobes continue to rotate, the trapped gas gets carried along the rotating lobes. The gas is essentially trapped in the pockets formed by the lobes and the housing. The rotating lobes then compress the gas as they move towards the outlet side of the pump.
3. Outlet Stage: As the lobes approach the outlet side of the pump, the volume between them and the housing decreases, resulting in the compression of the trapped gas. This compression raises the pressure of the gas, causing it to be expelled through the outlet port of the pump. The expelled gas is then discharged into the atmosphere or directed to a downstream process or another vacuum pump, depending on the application.
It’s important to note that a Roots vacuum pump operates as a non-contacting pump, meaning that there is no physical contact between the lobes or between the lobes and the housing. This characteristic eliminates the need for lubrication within the pump and reduces the risk of contamination or oil vapor backstreaming into the vacuum system.
Roots vacuum pumps are known for their high pumping speed and ability to handle large volumes of gas. However, they are not capable of achieving high vacuum levels on their own. To achieve higher vacuum levels, a Roots pump is often used in conjunction with other vacuum pumps, such as rotary vane pumps or diffusion pumps, in a hybrid or combination pumping system.
In summary, a Roots vacuum pump operates based on the principle of positive displacement. It utilizes synchronized rotating lobes to trap and compress gas, allowing it to be discharged at a higher pressure. The non-contacting design of the pump eliminates the need for lubrication and reduces the risk of contamination. Roots vacuum pumps are commonly employed in various industrial applications, especially when high pumping speed and large gas handling capacity are required.

What Is the Vacuum Level and How Is It Measured in Vacuum Pumps?
The vacuum level refers to the degree of pressure below atmospheric pressure in a vacuum system. It indicates the level of “emptiness” or the absence of gas molecules in the system. Here’s a detailed explanation of vacuum level measurement in vacuum pumps:
Vacuum level is typically measured using pressure units that represent the difference between the pressure in the vacuum system and atmospheric pressure. The most common unit of measurement for vacuum level is the Pascal (Pa), which is the SI unit. Other commonly used units include Torr, millibar (mbar), and inches of mercury (inHg).
Vacuum pumps are equipped with pressure sensors or gauges that measure the pressure within the vacuum system. These gauges are specifically designed to measure the low pressures encountered in vacuum applications. There are several types of pressure gauges used for measuring vacuum levels:
1. Pirani Gauge: Pirani gauges operate based on the thermal conductivity of gases. They consist of a heated element exposed to the vacuum environment. As gas molecules collide with the heated element, they transfer heat away, causing a change in temperature. By measuring the change in temperature, the pressure can be inferred, allowing the determination of the vacuum level.
2. Thermocouple Gauge: Thermocouple gauges utilize the thermal conductivity of gases similar to Pirani gauges. They consist of two dissimilar metal wires joined together, forming a thermocouple. As gas molecules collide with the thermocouple, they cause a temperature difference between the wires, generating a voltage. The voltage is proportional to the pressure and can be calibrated to provide a reading of the vacuum level.
3. Capacitance Manometer: Capacitance manometers measure pressure by detecting the change in capacitance between two electrodes caused by the deflection of a flexible diaphragm. As the pressure in the vacuum system changes, the diaphragm moves, altering the capacitance and providing a measurement of the vacuum level.
4. Ionization Gauge: Ionization gauges operate by ionizing gas molecules in the vacuum system and measuring the resulting electrical current. The ion current is proportional to the pressure, allowing the determination of the vacuum level. There are different types of ionization gauges, such as hot cathode, cold cathode, and Bayard-Alpert gauges.
5. Baratron Gauge: Baratron gauges utilize the principle of capacitance manometry but with a different design. They consist of a pressure-sensing diaphragm separated by a small gap from a reference electrode. The pressure difference between the vacuum system and the reference electrode causes the diaphragm to deflect, changing the capacitance and providing a measurement of the vacuum level.
It’s important to note that different types of vacuum pumps may have different pressure ranges and may require specific pressure gauges suitable for their operating conditions. Additionally, vacuum pumps are often equipped with multiple gauges to provide information about the pressure at different stages of the pumping process or in different parts of the system.
In summary, vacuum level refers to the pressure below atmospheric pressure in a vacuum system. It is measured using pressure gauges specifically designed for low-pressure environments. Common types of pressure gauges used in vacuum pumps include Pirani gauges, thermocouple gauges, capacitance manometers, ionization gauges, and Baratron gauges.

Can Vacuum Pumps Be Used in the Production of Solar Panels?
Yes, vacuum pumps are extensively used in the production of solar panels. Here’s a detailed explanation:
Solar panels, also known as photovoltaic (PV) panels, are devices that convert sunlight into electricity. The manufacturing process of solar panels involves several critical steps, many of which require the use of vacuum pumps. Vacuum technology plays a crucial role in ensuring the efficiency, reliability, and quality of solar panel production. Here are some key areas where vacuum pumps are utilized:
1. Silicon Ingot Production: The first step in solar panel manufacturing is the production of silicon ingots. These ingots are cylindrical blocks of pure crystalline silicon that serve as the raw material for solar cells. Vacuum pumps are used in the Czochralski process, which involves melting polycrystalline silicon in a quartz crucible and then slowly pulling a single crystal ingot from the molten silicon. Vacuum pumps create a controlled environment by removing impurities and preventing contamination during the crystal growth process.
2. Wafering: After the silicon ingots are produced, they undergo wafering, where the ingots are sliced into thin wafers. Vacuum pumps are used in wire saws to create a low-pressure environment that helps to cool and lubricate the cutting wire. The vacuum also assists in removing the silicon debris generated during the slicing process, ensuring clean and precise cuts.
3. Solar Cell Production: Vacuum pumps play a significant role in various stages of solar cell production. Solar cells are the individual units within a solar panel that convert sunlight into electricity. Vacuum pumps are used in the following processes:
– Diffusion: In the diffusion process, dopants such as phosphorus or boron are introduced into the silicon wafer to create the desired electrical properties. Vacuum pumps are utilized in the diffusion furnace to create a controlled atmosphere for the diffusion process and remove any impurities or gases that may affect the quality of the solar cell.
– Deposition: Thin films of materials such as anti-reflective coatings, passivation layers, and electrode materials are deposited onto the silicon wafer. Vacuum pumps are used in various deposition techniques like physical vapor deposition (PVD) or chemical vapor deposition (CVD) to create the necessary vacuum conditions for precise and uniform film deposition.
– Etching: Etching processes are employed to create the desired surface textures on the solar cell, which enhance light trapping and improve efficiency. Vacuum pumps are used in plasma etching or wet etching techniques to remove unwanted material or create specific surface structures on the solar cell.
4. Encapsulation: After the solar cells are produced, they are encapsulated to protect them from environmental factors such as moisture and mechanical stress. Vacuum pumps are used in the encapsulation process to create a vacuum environment, ensuring the removal of air and moisture from the encapsulation materials. This helps to achieve proper bonding and prevents the formation of bubbles or voids, which could degrade the performance and longevity of the solar panel.
5. Testing and Quality Control: Vacuum pumps are also utilized in testing and quality control processes during solar panel production. For example, vacuum systems can be used for leak testing to ensure the integrity of the encapsulation and to detect any potential defects or leaks in the panel assembly. Vacuum-based measurement techniques may also be employed for assessing the electrical characteristics and efficiency of the solar cells or panels.
In summary, vacuum pumps are integral to the production of solar panels. They are used in various stages of the manufacturing process, including silicon ingot production, wafering, solar cell production (diffusion, deposition, and etching), encapsulation, and testing. Vacuum technology enables precise control, contamination prevention, and efficient processing, contributing to the production of high-quality and reliable solar panels.
What Is a Vacuum Pump, and How Does It Work?
A vacuum pump is a mechanical device used to create and maintain a vacuum or low-pressure environment within a closed system. Here’s a detailed explanation:
A vacuum pump operates on the principle of removing gas molecules from a sealed chamber, reducing the pressure inside the chamber to create a vacuum. The pump accomplishes this through various mechanisms and techniques, depending on the specific type of vacuum pump. Here are the basic steps involved in the operation of a vacuum pump:
1. Sealed Chamber:
The vacuum pump is connected to a sealed chamber or system from which air or gas molecules need to be evacuated. The chamber can be a container, a pipeline, or any other enclosed space.
2. Inlet and Outlet:
The vacuum pump has an inlet and an outlet. The inlet is connected to the sealed chamber, while the outlet may be vented to the atmosphere or connected to a collection system to capture or release the evacuated gas.
3. Mechanical Action:
The vacuum pump creates a mechanical action that removes gas molecules from the chamber. Different types of vacuum pumps use various mechanisms for this purpose:
– Positive Displacement Pumps: These pumps physically trap gas molecules and remove them from the chamber. Examples include rotary vane pumps, piston pumps, and diaphragm pumps.
– Momentum Transfer Pumps: These pumps use high-speed jets or rotating blades to transfer momentum to gas molecules, pushing them out of the chamber. Examples include turbomolecular pumps and diffusion pumps.
– Entrapment Pumps: These pumps capture gas molecules by adsorbing or condensing them on surfaces or in materials within the pump. Cryogenic pumps and ion pumps are examples of entrainment pumps.
4. Gas Evacuation:
As the vacuum pump operates, it creates a pressure differential between the chamber and the pump. This pressure differential causes gas molecules to move from the chamber to the pump’s inlet.
5. Exhaust or Collection:
Once the gas molecules are removed from the chamber, they are either exhausted into the atmosphere or collected and processed further, depending on the specific application.
6. Pressure Control:
Vacuum pumps often incorporate pressure control mechanisms to maintain the desired level of vacuum within the chamber. These mechanisms can include valves, regulators, or feedback systems that adjust the pump’s operation to achieve the desired pressure range.
7. Monitoring and Safety:
Vacuum pump systems may include sensors, gauges, or indicators to monitor the pressure levels, temperature, or other parameters. Safety features such as pressure relief valves or interlocks may also be included to protect the system and operators from overpressure or other hazardous conditions.
It’s important to note that different types of vacuum pumps have varying levels of vacuum they can achieve and are suitable for different pressure ranges and applications. The choice of vacuum pump depends on factors such as the required vacuum level, gas composition, pumping speed, and the specific application’s requirements.
In summary, a vacuum pump is a device that removes gas molecules from a sealed chamber, creating a vacuum or low-pressure environment. The pump accomplishes this through mechanical actions, such as positive displacement, momentum transfer, or entrapment. By creating a pressure differential, the pump evacuates gas from the chamber, and the gas is either exhausted or collected. Vacuum pumps play a crucial role in various industries, including manufacturing, research, and scientific applications.

Types of vacuum pumps
A vacuum pump is a device that pulls gas molecules out of a sealed volume and maintains a partial vacuum. Its job is to create a relative vacuum within its capabilities. Several types of vacuum pumps are available, including scroll and rotary piston models. Each has its own characteristics and uses. To learn more, read this article. 
Screw Pump
Screw vacuum pumps use a mechanical screw to move an air or gas chamber to the axial housing wall. The movement of the chamber reduces the volume of gas, which is pre-compressed before being expelled through the pressure connection. These pumps can be single-pitch models or variable-pitch models. Variable pitch models feature variable pitch rotors that help distribute heat loads evenly across the rotor. Some models also include a thermostatic control valve that shuts off the pump if the water temperature gets too high. Screw vacuum pumps are available in single-ended or double-ended designs. Single-ended and double-ended screw pumps provide up to 3.7 x 10-4 Torr and an ultimate vacuum of 900 m3/h (560 cfm), which is sufficient for many industrial processes. Progressive cavity pumps are particularly suitable for vapor compression applications. These pumps also have an internal rotor to minimize layer formation. Combined with air cooling, they are suitable for use in hazardous environments. In addition, the screw rotor design prevents the build-up of substances in the pump cavity that could react with high temperatures. These pumps are also easily removable for quick cleaning. Screw vacuum pumps are also designed for low cost and minimal maintenance. Agknx screw vacuum pumps are designed in Germany and are very reliable and economical. Pump performance depends on cooling system and temperature. The temperature of the water used should be kept within a certain range, otherwise the pump may overheat and fail. Screw vacuum pumps are often used in scientific experiments. They are standard main pumps in large storage rings, gravitational wave detectors, and space simulation chambers. One of the largest ultra-high vacuum chambers in the world is made of screw vacuum pumps. An example is the KATRIN experiment. There are two types of screw vacuum pumps: oil-sealed and dry. Oil-sealed screw pumps use oil as a sealant and coolant. They are suitable for demanding vacuum applications such as woodworking and plastics processing. Dry screw pumps have an air-cooled chamber, and they can achieve higher vacuum levels than oil-sealed pumps.
Rotary Piston Vacuum Pumps
Rotary Piston Vacuum Pumps provide the rugged performance essential for applications requiring vacuum. They can deliver flow rates up to 1280 acfm and reach deep vacuum levels up to 0.0004 Torr. They are available in single-stage and two-stage models. The report also provides detailed information about the key players, their financial status, and business overview. A rotary piston vacuum pump is a versatile and affordable vacuum device. They are available in single-stage and two-stage configurations with higher capacity and higher vacuum.

They are also ideal for helium leak detectors and other analytical equipment. Scroll vacuum pumps are available in a variety of models, including the diaphragm, turbine, and oil-dry scroll models. They are used in a variety of industries, including the semiconductor, biotechnology, and pharmaceutical industries. Flexible and durable oil-free scroll vacuum pumps are an excellent choice for light industrial, general laboratory, and research applications. They also offer several advantages over other vacuum pumps, including low operating costs and environmental sustainability. Scroll vacuum pumps do not require oil, which is a big advantage in terms of cost. Scroll vacuum pumps are also quieter. Scroll vacuum pumps are designed for low, medium, and high vacuum systems. They create a high vacuum and cannot tolerate particles. Although they are relatively small, they are ideal for vacuum laboratory applications and are also suitable for dry vacuum pumping. They can be combined with chemically resistant PTFE components, making them more suitable for chemical applications. Scroll vacuum pumps feature a unique design that makes them very versatile and efficient. The pump has two helical structures, one is fixed and the other is rotating, which can effectively pump gas and liquid. When the rotor begins to move, the gas is compressed slightly and then flows through the system to the exhaust port. Scroll vacuum pumps are efficient, oil-free and compact. Known for their high tolerance to the atmosphere, they feature sensorless INFORM(r) control to minimize noise and vibration. These vacuum pumps are ideal for low to medium flow applications including analytical equipment, freeze dryers, vacuum coaters and mass spectrometers. The most important advantage of a scroll vacuum pump is its reliability. They can be used for three years or more without problems and are easy to maintain. With proper maintenance, they can reduce repair costs. 
Diaphragm vacuum pumps
Diaphragm vacuum pumps are used in a variety of industrial processes. These pumps use an elastic diaphragm fixed around the outer diameter. They are efficient and can handle most types of liquids. They are commonly used for dewatering, filling and water removal. These pumps are easy to maintain. Diaphragm vacuum pumps are available in a variety of sizes and power outputs. Oil-free diaphragm vacuum pumps do not require oil, lubrication and cooling. These pumps are compatible with many types of laboratory equipment. Diaphragm vacuum pumps are equipped with dual voltage motors and DC drives for greater flexibility and durability. Diaphragm vacuum pumps can achieve higher vacuum levels than rotary vane pumps. They are more efficient than diaphragm pumps. They do not require oil and require less maintenance than their rotary vane counterparts. However, the diaphragms of these pumps may need to be replaced every few years. Diaphragm vacuum pumps are the most popular type of vacuum pump and can be used for a variety of applications. They can be used for everyday work and can be large enough to be used in a vacuum oven or rotary evaporator. Diaphragm vacuum pumps use pulsed motion to move air. They eliminate the need for oil and are highly chemical and steam resistant. They can handle a wide variety of samples, including high viscosity liquids. Diaphragm vacuum pumps are generally smaller than other types of vacuum pumps. Scroll pumps are made of metal and are generally recommended for solvent and water samples. They are not recommended for high acid samples. However, they are suitable for freeze drying. They can also be used for concentration applications. In this way, they have greater displacement capacity and can reach higher ultimate vacuum levels.
