FEATURES Long Hold Time Optional Gold Plated design results in long hold times of 12 to 16 hours. Can fill the 2” cold trap with 3 liters of liquid nitrogen in the morning and run all day without refilling. The 6” trap requires 6 liters a day. OPTIONAL WATER COOLED BAFFLE Prevents back streaming of oil from diffusion pump when cold traps run out of liquid nitrogen, with no loss in conductance
HIGHEST CONDUCTANCE Oversized to retain conductance of diffusion pump. LOW OUT GASSING Polished and (optional) gold plated surfaces reduce out gassing. EASY FILLING Can be filled easily through a large diameter combination fill and vent port AUTOMATIC FILL Normally does not require automatic fill systems unless overnight operation is required. SELF CLEANING Hold time is such that unit can warm up overnight which will allow pumping of condensable items out of the trap. MATERIALS OF CONSTRUCTION Heli-arc welded stainless steel with copper baffles. RELIABLE AND EFFICIENT CRYOGENIC DESIGN Manufactured at our facility LOW COST Cost no more than conventional cold trap and water baffle
