The CS204I-FMX-4 provides the same high performance as our CS204I-FMX-1SS with its all stainless steel construction and welded stainless steel instrumentation skirt but provides a larger than standard sample space. The vacuum shroud comes standard with four window ports, and a fifth port can be added at the top.
The CS204I-FMX-4 is powered by our DE-204 series closed cycle cryocoolers. These liquid helium free cryostats use a pneumatically driven Gifford-McMahon cycle to cool the sample. CS204-FMX-4低溫冷卻系統 特點:
Cryogen free GM cryocooler
Welded stainless steel construction for better vacuum.
Large, clear view optical windows (1.5 in.)
Large sample viewing angle for optical collection (F/# = 1.25)
