CS204-FMX-1AL

The CS204-FMX-1AL offers a wide range of flexibility at a low cost, making it an excellent choice for most sample and device testing. This system has similar features to the CS202-DMX-1AL, however it provides almost twice the cooling capacity. Consequently this system is less sensitive to experimental and parasitic heat load changes arising from sample size, number of wires, number of windows, etc.

The CS204-FMX-1AL is powered by our DE-204 series closed cycle cryocooler. These liquid helium-free cryostats use a pneumatically driven Gifford-McMahon cycle to cool the sample.
