CS204B
The ARS manufactured CS204B is a medium cooling power, true UHV cold head (10-11 Torr) where all of the rubber o-ring seals have been replaced with welded joints and metal seals. A CF flange is welded directly to the cryocooler.
This true UHV system is bakeable to 80 C, and the 10 K CS204AB is bakeable to 200 C if the displacer is removed. (Special training required.)
Cold tip extensions are available to put the sample right where it is needed in the chamber.
