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. It’s a lighter, more compact, and convenient replacement to traditional 4-walled helium containers.
