Agilent Varian NHS-35 Diffusion High Vacuum Pump - REBUILT

These diffusion pumps come with full thermal protection and quick-cool coils. HS-16 through 35 come with sight glass / fill and drain assemblies. Our HS-32 pumps have 32" ASA flanges. The Agilent Varian HS-20 pump is wired for either 208V or 240V. For $1,500 we will convert them to 480V. We also carry Agilent Varian diffusion pump LN2 traps and baffles and valves.
