Description

Agilent Varian VHS-4 Diffusion High Vacuum Pump - REBUILT

The Agilent Varian VHS Series bulge contour increases gas capture and maintains lower pressure for the process. These VHS diffusion pumps have sight glass/fill and drain assemblies for continuous monitoring and easy maintenance of pump fluid. Finned boilers increase surface area, prolonging fluid life. Full thermal protection and quick-cool coils are also standard. Please let us know if you would like a quote for a different heater voltage or for repair service of your pump.

We also carry Agilent Varian diffusion pump LN₂ traps and baffles and valves.
