Cryogen Free Dilution Refrigerators

Cryogenfree Dilution Refrigerator
Product Code: ^DRYICE^{EASYFIT 200} and ^DRYICE^{EASYFIT 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 ^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
• Cryostat
• 1K and dilution low temperature stages.
• Pumping / gas handling system
• Temperature controller (automatic) and matched sensors
• Mixture and ⁴He gas dumps with gas handling manifold

Options / customisation:

• Further vibration isolation
• Additional wiring
• Coaxial cables
• Wave guides
• Line of sight ports
• Optical windows
• Sample top-loading
