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 range of coax includes miniature braided coax for measurements at millikelvin temperatures and ultra-low loss Cobra-flex cable that has built-in corrugation to prevent creep of the dielectric material./ All coax is priced by the metre./
