Cryogenfree Dilution Refrigerators.

Cryogenfree Dilution Refrigerator
Product Code: ^DRYICE^{EASYFIT 200} and ^DRYICE^{EASYFIT 400}

A range of compact cryogenfree 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 ^DICE^GH – 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.

Components:-

• Closed cycle cooler, cold head, and compressor
