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?

Rebuilt Vacuum Pumps

If you need to replace your vacuum pump but are on a tight budget, you can find rebuilt vacuum pumps online cheaper than a brand-new unit with comparable performance. These rebuilding processes are comprehensive and, typically, the pumps are backed with warranties.
