Closed Cycle Cryostat Sample in Vacuum

4K Pulse Tube Cryostat

The 4K cryostat offers continuous 4K refrigeration using a pulse tube cryorefrigerator. The unique sleeve and reservoir design of the 4K cryostat provides refrigeration without any direct mechanical contact between the 4K station and the cryorefrigerator. This design feature allows for ultra-low vibration operation 3-5nm.



Cooling Capacity             ≥0.5W @ 4.2K*
Base Temperature          ≤3.2K with no load*
