Laboratory vacuum pumps are devices that create vacuums in a laboratory environment. A vacuum is defined as a space devoid of matter, including gas.
Though outer space comes the closest, a truly perfect vacuum does not exist. Practically speaking, most manufactured vacuums are simply spaces where the pressure is significantly lower than the external atmospheric pressure. These partial vacuums have many applications in biology, chemistry, and clinical research.
Vacuum pumps, which can range from benchtop units to much larger systems, are used in experiments that involve aspirating, controlling, or inducing solvent evaporation in concentrators. Vacuum ovens, desiccators, driers, and rotary evaporators are other types of lab equipment that use vacuum pumps. Without a vacuum, rotary evaporation would not be possible. Though standalone vacuum pumps are top-rated devices, most only provide enough power for one workstation.
More sophisticated vacuum systems also exist which can service multiple workstations, providing an alternative to buying multiple pumps. Other than the number of workstations, the type of chemicals or concentrations you are using should be considered when getting a lab vacuum pump system.
Types of Vacuum Pumps & Vacuum Depths
There are many different vacuum pumps, most of which comprise stainless steel hardware. Both oil and oil-less pumps exist, each with distinct advantages. Pumps sometimes use oil to help create and maintain the vacuum environment while preventing corrosion inside the pump.
However, these types of pumps require more maintenance and need to have their oil changed periodically. Another primary consideration is the vacuum’s strength, quality, or depth that you need.
- Low: Also known as coarse or rough vacuum, used chiefly for moving liquids.
- Medium: This can be achieved using one pump, which is appropriate for solvent recovery.
- High: Normally requiring multi-stage pumpin
Depending on these specifications and the vacuum applications you will be performing, some pumps will make more sense than others. Below is a list of the most common types.

Rotary vane vacuum pumps, also known as RV pumps, are high-performance, oil-sealed pumps.
These are some of the most common vacuum pumps found in laboratories and, due to their use of oil, can reach deeper pressures than dry lab vacuum pumps. The oil used must be changed periodically, and maintenance is typically recommended after every 3,000 hours. An example of one includes the high vacuum pump. It is a two-stage, direct drive rotary vane pump that offers a high or ultra-high vacuum, ideal for research, development, and industrial fields.

Along with piston pumps, diaphragm vacuum pumps offer an oil-free vacuum solution. Instead of using oil to create an airtight seal, these pumps use a variety of valves that open and close in a pulsing motion similar to the human heart. These pumps operate at a much lower pressure than those using oil.

Also referred to as hybrid pumps, this type of pump combines the functionality of both a diaphragm and a rotary vane pump. The diaphragm pump keeps the oil in the RV pump under vacuum pressure, reducing the need for oil changes. Combination pumps are best suited for substances with high vapor loads but also need the fine vacuum of an RV pump. Acids and freeze dryers are two examples of such applications.

Like the piston style, scroll pumps are another dry pump type often found in labs. These pumps are called dry scrolls because they use two spiral scrolls to compress the air and vapors before they are moved to the exhaust. These can achieve much deeper vacuum levels and higher pumping speeds than other dry pumps. Scroll pumps are often used to de-gas, distill, or concentrate substances.
We Offer Piston Pump Leases to Fit Every Need
Laboratory vacuums, pumps, aspirators, and aspiration systems aid in various laboratory applications requiring a vacuum. Having the best vacuum technology in your laboratory will increase your ability to perform precise, accurate work. However, if budget is getting in the way, you may find yourself without the pumps you require.
If that’s the case, consider leasing your lab equipment instead, as our lab equipment lease program is an excellent, creative option for startup, middle market, and enterprise biotechs and biopharma companies.
Whether you need to lease a lab vacuum, vacuum pump, rotary evaporator, or lyophilizer, we can help. In addition to this equipment, we offer a wide selection of other general equipment that includes fume hoods, biological safety cabinets, and more. Give us a call at (510) 982-6552 or fill out our contact form so that we may discuss your needs in further detail.
This off-balance sheet financing structure provides three options at the end of the term. The lessee has the option to return the equipment to the lessor, renew at a discounted rate, or purchase the instrument for the fair market value. Monthly payments are also 100% tax deductible which yields additional monetary savings.
If you recently bought equipment, Excedr can offer you cash for your device and convert your purchase into a long-term rental. This is called a sale-leaseback. If you’ve paid for equipment within the last ninety days, we can help you recoup your investment and allow you to make low monthly payments. This also frees up money in your budget rather than tying it down to a fixed asset.
