Cryofab CMSH-60 Liquid Helium Dewar 60L 304 Stainless Steel Cryogenic Vessel

Cryofab CMSH-60 Liquid Helium Dewar 60L 304 Stainless Steel Cryogenic Vessel

The Cryofab CMSH-60 is a 60-liter liquid helium storage dewar constructed from 304 stainless steel. It uses vapor-cooled multishield technology combined with superinsulation to minimize boil-off loss during storage and transport. The unit features a large neck opening, VAC valve, pressure gauge, and a carry ring on the top assembly, and sits on a wheeled caster base for easy repositioning. Manufactured in January 1992 by Cryofab, Inc.

Applications

Liquid helium dewars like the Cryofab CMSH-60 are standard vessels in cryogenic research, superconducting magnet operations, and low-temperature physics labs. They are used to store, transport, and dispense liquid helium — which boils at approximately −269°C (4.2 K) — while keeping evaporative losses to a minimum through multilayer vacuum insulation. The CMSH series from Cryofab was designed specifically for laboratory and industrial environments where reliable, low-loss helium containment is required. Common applications include cooling superconducting magnets in MRI systems and NMR spectrometers, cryogenic semiconductor research, and transfer to smaller research vessels or experimental setups. This unit was deinstalled from a cryogenic research facility that ceased operations in December 2005 and is appropriate for labs needing a mid-size portable helium dewar.
