Ultra High Vacuum (UHV) Cryostat

The ST-400 ultra high vacuum (UHV) cryostat from Janis Research offers the easiest technique for providing cooling in an ultra-high vacuum environment. The instrument is designed with the features of the basic SuperTran cryostats and integrated with many of the features relating to UHV requirements.

The ST-400 cryostat can be custom built so that the cold finger length and conflat-style vacuum flange can be sized to match a user's chamber.
