Cryogenfree Dilution Refrigerator
Product Code: DRYICEEASYFIT 200 and DRYICEEASYFIT 400

A range of compact cryogen-free dilution refrigerator systems, sample in vacuum, using GM closed cycle cooler with vibration eliminated by a bellows system or a pulsed tube cooler.

A 1K stage allows full condensation of the ³He/4He mixture charge, this circulating mixture is controlled by DICEGH dilution system gas handling and controller.

The base temperature for this system is 15mK with temperature control up to 4.2K (up to 300k optional) and a range of cooling powers of 200mW to 400mW at 100mK.
