DRY ICE 300mK He-3 Cryostat
The DRY ICE 300mK He3 Continuous cryostat is a closed cycle system with the highest cooling powers at 300mK currently on the market. This compact cryostat is customisable to suit your requirements, particularly for large heat load experiments.
The cooler is isolated using flexible bellows to minimise vibration which extends into the cryostat where thermal contact to the rest of the system is obtained by the introduction of exchange gas. There is no mechanical contact to any other part of the system from the cooler.
Using the ICECUBE automatic gas handling system, the flow of gas during cool-down and operation can be controlled.
The system is designed to run continuously at 3He temperatures (below 500mK).
