Laboratory pumps are suitable for a wide range of applications. Vacuum pumps, such as rotary vane and diaphragm pumps, are used in freeze drying, centrifugal evaporation, and more. Non-vacuum pumps, such as syringe and peristaltic, are used in automatic pipetting, titration, and other applications. For a list of pump manufacturers, see our online directory:

6 Questions to Ask When Buying a Lab Pump:

  1. What depth of vacuum is required for the intended applications? There are many options for low, medium, high, and even ultra-high vacuums.
  2. What pumping rate do you require?
  3. Is a dry (oil-free) pump suitable? They do not require oil changes and have lower overall maintenance costs.
  4. What types of solvents will be used? Will the pump require a corrosion-resistant flow path?
  5. If buying a non-vacuum pump: what pressure (psi) is best for your application? Syringe pumps work at much higher pressures than peristaltic pumps.
  6. How much noise does the pump generate?

Liquid Handler Pumps

A factor that may be overlooked when purchasing a new liquid handler is the pump. Not all pumps are compatible with all liquid handlers, which necessitates careful consideration on the buyer’s part to ensure that their pump is not only suitable for their application, but also compatible with their liquid handler’s hardware.

Direct Current Vacuum Pumps

Compared to alternating current pumps, direct current pumps are often more durable, energy efficient, and quieter. Furthermore, they can offer control over the speed of the vacuum process. Learn more about selecting the right vacuum pump for your lab at
