This is a replacement Indiium Gasket Pre-cut Set for the CTI CT-400 ON-BOARD Cryopumps.

The CTI-Cryogenics Cryo-Torr CT-400 ON-BOARD pumps, are one of the two major components that make up the Cryo-Torr Pumping System. The second component is the Compressor (also sold on this website). The Cryo-Torr 400 ON-BOARD Cryopump, provides fast, clean pumping of all gases in the 10-3 to 10-9 Torr range. Standard applications include, Semiconductor, Aerospace & Vacuum coating as well as R&D.

The cryo-pump operates on the principle that gases can be condensed and held at extremely low vapor pressures, achieving high speeds and through puts. This pump is a highly-reliable and rugged unit that requires minimal servicing. Since the cryo-pump exposes no moving parts, operating fluids, or backing pumps to the vacuum, the possibility of system or process contamination from the cryo-pump itself is eliminated.

Descripition, Installation, Regeneration, and Maintenance Procedures are covered in the .pdf at the downloads section to the side.
