WOB-L 1 Ph Piston Pump with North America
Welch, 2567B-50, WOB-L 1 Ph Piston Pump with North America Plug 115V, 27.6 Maximum VacuumReliable 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.FeaturesEconomicalOil FreeAdjustable VacuumApplicationsVacuum FiltrationMany 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. ... Show More Show Less
