The CS204-FMX-3AL offers a wide range of flexibility at a low cost, making it an excellent choice for most sample and device testing. This system is well suited for optical, electrical, and magnetic sample testing.

The CS204-FMX-3AL is powered by our DE-204 series closed cycle cryocooler. This liquid helium-free cryostat uses a pneumatically driven Gifford-McMahon cycle to cool the sample.
