A compact cryogen-free ³He system for use an a UHV environment, sample in vacuum, uses a closed cycle cooler with vibration eliminated by a bellows system. A 1K stage allows full condensation of the ³He charge which extends the hold time at a base temperature of 300mK to 40 hours, and gives a fast regeneration time.

Options/customisation:

• Further vibration isolation
• Additional wiring
• Coaxial cables
• Wave guides
• Line of sight ports
• Base temperature: <270mK
• Hold Time: 70 hours
• 3he Charge: 7 litres

 Product code: ^DRYICE^{3 UHV}
