The CS202I-DMX-15 offers high vacuum capability for low-temperature Electron Paramagnetic Resonance (EPR) and Electron Spin Resonance (ESR) experiments. The o-ring design on the quartz cuvette provides for easy sample change without having to disassemble the system. There is a choice of either a sapphire or copper sample rod.

The Low-Temperature EPR Cryostat is powered by our DE-202 series closed cycle cryocooler. This liquid helium free cryostat uses a pneumatically driven Gifford-McMahon cycle to extract heat from the system.
