With its all stainless steel construction and a welded stainless steel instrumentation skirt, the CS202I-DMX-4 achieves the same high performance as our CS202I-DMX-1SS. But this cryostat has a larger than standard sample space which provides room to fit diamond anvil cells. The vacuum shroud comes standard with four window ports, however a fifth port can be added at the end of the sample block.

The CS202I-DMX-4 is powered by our DE-202 series closed cycle cryocooler. This liquid helium-free cryostat uses a pneumatically driven Gifford-McMahon cycle to cool the sample.
