ICE Cryogenic Equipment CRYOBITZ Cryogenic Laboratory Spares

DRY ICE 300mK He-3 Benchtop Cryostat

The DRY ICE 300mK He3 system is a single shot benchtop cryostat with bottom loading sample space. This compact cryogen-free system allows for a fast turnaround and is perfect for detector work at ultra-low temperatures.

A 1K stage allows full condensation of the ³He charges which extends the hold time at a base temperature of <290mK to 80 hours and gives a fast regeneration time.
