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.
Cryogenic wiring requires careful selection of wire materials and heatsinking components to provide the lowest heat-leak into the low temperature environment whilst maintaining measurement integrity.
Our cryogenic wire types include Constantan, Copper, BeCu, Manganin and NbTi superconducting wire and all are available woven in Cryoloom® ribbon cables for cryo wiring interconnects on dilution refrigerator, He3 and sub-4K measurement systems.
