CS204-FMX-1SS.png

The CS204-FMX-1SS is our standard intermediate cooling power cryostat for optical and electrical measurements. This high performance system offers an all stainless steel constructed vacuum shroud along with a welded stainless steel instrumentation skirt. This system is capable of achieving vacuum levels of 10-7 Torr with an appropriate vacuum system. The nickel plated copper radiation shield provides low emissivity which is ideal for low temperature experiments.

The CS204-FMX-1SS is powered by our DE-204 series closed cycle cryocooler. WIth twice the 4K cooling power of the DE-202 cryocooler, the base temperature of this system is much more forgiving of experimental and parasitic sources of heat load.
