Replacement Baffles, Water Fittings & Cold Caps for Diffusion Pumps
Agilent water-cooled Halo Baffles provide nearly twice the speed at the pump inlet as that achieved with other baffles. They do not add any height to the system. These baffles are very economical and decrease backstreaming and outgassing.
Agilent extended Cold Cap is an option that fits inside the VHS-4, VHS-6 and VHS-10 pumps. It replaces the standard cold cap to reduce backstreaming, yet it retains 80% of the pump's speed.
