Welch 2534B-01 WOB-L 1 Ph Piston Pump with North America Plug 115V

WOB-L 115V 1 Ph Piston Pump with North America Plug

Reliable WOB-L Piston pumps are perfect for many common laboratory vacuum applications. Features: Vacuum and Pressure - to 70 Torr (27.2"Hg). Includes Vacuum and Pressure Regulators and Gauges - simple to adjust and monitor 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. For use with dry or aqueous vapor applications only.

Features

• Economical
• Oil Free
• Adjustable Vacuum / Pressure

Applications

• Aspiration
  • Accumulate your waste solvents with ease using these affordable vacuum pumps. Configure an appropriate collection reservoir to capture liquid prior to pump. Select a Standard Duty WOB-L pump for aqueous vapors or Chemical Duty DryFast pump for organic solvent or harsh acid / base fumes.
• 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.
