Description:    

The Cooke long life traps are designed for vacuum applications where it is desirable to reduce oil and or water vapor contamination of the environment.  The long life traps prevent diffusion pump oil from entering the vacuum system with little effect on the conductance or the pump down time.  The traps also pump water vapor and other condensable gases at very high speeds, shortening the pump down times for the ion pump systems.

Although the long life cold trap series may be used directly above the diffusion pumps, it is preferable to use either a water-cooled or ambient baffle between the long life cold trap and the pump.  This combination reduces the heat radiated through the system thus reducing the consumption of the refrigerant.  The water baffle may be included in the trap itself or separately fitted in the system.
