Agilent / Varian AX-65 Diffusion Pump
The AX-65 diffusion pump is a high-performance, air-cooled pump designed with bench-top analytical instruments in mind. Its vertical finned boiler and high power provide stable pumping and high helium pumping speed. This pump can be ordered with a cold cap or a dense baffle. The pump includes a fluid-level sight glass that indicates the fluid level at all times.
