Details

  • Economical
  • Oil Free
  • Adjustable Vacuum / Pressure

Use these affordable oil-free pumps to provide convenient vacuum throughout the lab. Welch WOB-L piston pumps provide adjustable vacuum for filtration, SPE, vacuum ovens, and more. These pumps are an efficient alternative to water aspirators. Select vacuum range 100 to 5 torr; flow range 22 to 201 l/min. For use with dry or aqueous vapor applications only.

Includes Vacuum and Pressure Regulators and Gauges - simple monitoring and adjustment of vacuum level and delivery pressure. Inlet Water Trap - float ball rises to seal off pump from accidental ingestion of water. Muffler quiets pump and filters discharge air.

1-head models – Ideal for filtering and SPE. Select low flow model for 1-2 filter funnels; higher flow model for up to 6 filter funnels. Can also be used as pressure pumps.

2-head models – Use low vacuum / high flow for filter manifolds or lab automation; select high vacuum (e.g. 5 torr) / high flow for vacuum ovens.
