Vacuum Pumps: Cryogenic Sorption

From MDC Vacuum Products LLC
 

 
Sorption roughing pumps or sorption pumps are used for pumping systems from atmospheric pressure to a pressure of approximately 10-2 Torr. They rely on the dispersion forces existing between a gas and a surface to bind gas molecules on chilled surfaces inside the pump. In other words, they pump by
