Cryogenics
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.

Wiring
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.

Measurements
Sample mounting components include glues, greases and dissolvable GE-varnish for thermalisation of samples at cryogenic temperatures. For mounting of high power components such as laser diodes we have a range of Indium foils in different thicknesses to provide demountable thermalisation.
Our ranges of measurement cable assemblies, using custom CMRflex cable, provide individually shielded twisted pair connections for the best performance in ultra-low noise measurement systems.

Receptacle cover
(FR105Cover [02-31-015])
particularly useful for this connector as the large pins conduct a lot of cold to outside the cryostat during helium transfers.
Ideal for high currents to drive small and medium sized superconducting magnets
