An instrument demonstrating the freezing of water by its evaporation: Mr. Jones explained to his students that by the use of a cryophorous water could turn into ice by its own evaporation.

A cryophorus is a device t for showing the freezing of water by its own evaporation.

cryophylactic (adjective) (not comparable)
Resistant to low temperatures: Cryophylactic bacteria are those organisms that can withstand freezing.
cryophysics (s) (noun) (no pl)
A branch of physics that is concerned with processes and phenomena at temperatures approaching absolute zero: Mary wanted to take a class in cryophysics which dealt with the occurrences or marvels connected with sutstances at very low temperatures.
cryophytes (s) (noun), cryophytes (pl)
A plant that grows on ice or snow: Algae, bacteria, and fungi are considered to be cryophytes as they thrive well at low temperatures in the winter season or in cold climates.
cryoplanation (s) (noun), cryoplanations (pl)
Land erosion that results from processes associated with intensive frost action: In his geology seminar, Dr. Green explained that the effects of movement on land, caused by ice action, was termed cryoplanation
cryoplankton (s) (noun), cryoplankton (pl)
Minute organisms existing in persistent snow, ice, and glacial waters: Cryoplankton, especially the algid flora, inhabit snow, ice, and the ice water of the alpine and polar areas.
cryoprecipitate (s) (noun), cryoprecipitates (pl)
A frozen blood product formed from plasma: A cryoprecipitate is a solid matter which forms when soluble material is cooled, especially with reference to the precipitate that forms in normal blood plasma which has been subjected to cold precipitation and which is rich in factor VIII.
cryoprecipitation (s) (noun), cryoprecipitations (pl)
The process of forming a solid that settles from a solution: The cryoprecipitation that forms when plasma is frozen and then thawed which is especially rich in fibronectin (secreted proteins) and a blood clotting factor, that, when acting together, can form a blood clot shortly after platelets have broken at the site of the wound.
cryopreservation (s) (noun), cryopreservations (pl)
The process of protecting biological tissues at an extremely low temperature normally at -80°C.: Cryopreservation is the maintenance of the viability of excised tissues or organs at extremely low temperatures.

Cryopreservation includes the process of storing semen, ova, corneas, embryos, bone marrow, or body tissue at extremely low temperatures for future use.
