translation icon : criógeno
  • The scientists carefully monitored the flow rate of the cryogen to ensure optimal refrigeration in the physics experiment.
  • transfer of the cryogen

The disadvantage of hydrogen has always been that it's such a deep cryogen.

Examples

  • The cryogenic system uses no cryogens and produces 10-40 W of cooling power using a cooling mechanism similar to that used by a household refrigerator.

  • In the first, the liquid crystal display continuously shows the level and consumption rate of cryogen.

    Academic text (1996)

  • The vacuum insulation on the hoses results in reduced consumption of cryogen.

    Academic text (1996)

  • The Optistat Bath is a helium bath cryostat that is suited for continuous low-temperature operation because of its efficient cryogen usage.

    Academic text (1996)

  • Rigaku/MSC has introduced the NitroGen miniature liquid nitrogen generator, a one-box solution for point-of-use generation, storage, and transfer of the cryogen.

    Academic text (2002)

  • The Optistat CFV is a compact, continuous-flow cryostat that draws its cryogen from an external supply and maintains a vacuum around the sample.

    Academic text (1996)

  • The stainless steel, vacuum-insulated transfer hoses from VBS Industries are intended for the frost-free transfer of liquid nitrogen and other cryogens.

Morphology

cryogen = cryo + gen

Formed from the technical Greek combining forms 'cryo-' (cold) + '-gen' (producer/thing), which are not standalone English words and do not yield the precise technical meaning to an average B1 learner.

Etymology

Cryogen comes from Greek parts cry- meaning 'cold' and -gen meaning 'to make' or 'produce', like in the word generate. So a cryogen is a substance that 'produces' or keeps things very cold, for example liquid nitrogen used to store samples.
