CMSH Series

Portable Liquid Helium Dewars

Designed for minimum-loss storage, transportation and dispensing of liquid helium. Our state-of-the-art vapor-cooled multishield technology with superinsulation ensures the lowest guaranteed loss rates*. The advanced insulation system results in quicker, more efficient cool down without nitrogen pre-cooling. Since there’s no LN₂ or helium gas circulation shielding, the CMSH is virtually maintenance free. Its a lighter, more compact and convenient replacement to traditional 4-walled helium containers.
