We supply liquid helium and nitrogen storage dewars, gas handling and safety equipment and a wide range of cryogenic components for low temperature measurement systems.
Our laboratory essentials include stycast epoxy for fixing cryogenic equipment, indium wire and foil for vacuum flanges and apiezon grease for heatsinking and lubrication.
Low temperature work makes great demands upon the electrical wiring used. Wire, connectors and heatsinking must be selected to minimise heatleak at low temperature. Laboratory cables need to be made professionally for low-noise performance.
Sample mounting components include non-magnetic JEDEC chip carriers and mPuck sample mounting stages for experiments below 4K, especially in vacuum when sample thermalisation needs to be achieved via demountable electrical connections.
CMR-Direct produces the industry's only commercial low temperature transformers, which coupled with Lock-In detection and narrow-band filtering, can provide ultra-low-noise performance for AC Resistivity and AC Susceptibility measurements.
Our ranges of cryogenic gloves have been developed to give contact protection down to -125°C against freezer burn and frostbite. The recommended gloves for liquid nitrogen handling have a wrist seal to prevent splashes entering the glove.
The mid-arm type (sometimes known as a gauntlet) extends up and provides protection from cold to mid-way up the forearm. When retrieving or placing products in liquid nitrogen atmospheres, we recommend waterproof cryogenic gloves as these are less porous to the cold gas.
