Baffles

Multi-Coolant Baffle, Cryo-Baffle, Water-cooled and Contamination Traps

GNB’s baffles are also called multi-coolant baffles because they can be chilled by a variety of liquids.  While they are often used in conjunction with a chiller, they can be used with cool water, liquid nitrogen and other liquids.  Their most common use is to trap contaminates in a vacuum system.  One such contaminant is oil from a diffusion pump.  In the high vacuum range, molecules of diffusion pump oil can wander from the pump and contaminate the vacuum process.  With GNB’s 5-bounce design, these oil molecules are trapped and then drip harmlessly back into the pump.
