Welch WOB-L Pump 2561

Description

Welch WOB-L Pump 2561

Reliable WOB-L Piston pump is perfect for many common laboratory vacuum applications. Features: Vacuum to 5 Torr (29.8"Hg). Includes Vacuum Regulator and Gauge - simple to adjust and monitor vacuum level. Inlet Water Trap - float ball rises to seal off pump from accidental ingestion of water. Muffler quiets pump and filters discharge air. For use with dry or aqueous vapor applications only.

Features:

Economical
Oil Free
Adjustable Vacuum

Applications:

Vacuum Filtration

Many filtrations require only minimal vacuum to proceed; deep vacuum is not required. Vacuum pump flow required is roughly proportional to the total surface area of filters being used. Filtration of particulate-clogging samples can be improved somewhat with deeper vacuum, but a combination of larger filter surface area, smaller samples, and sequential use of decreasing porosity filter papers may also be required for timely filtration. Choose a standard duty vacuum pump for aqueous vapors; use a PTFE pump for resistance to harsh chemicals.
