What does cryogenically mean?
Cryogenically is an adverb describing an action or process performed at extremely low temperatures, usually below about −150 °C. It is used in scientific, medical, industrial, and food-preservation contexts, especially when discussing the freezing, cooling, storage, or preservation of biological samples, vaccines, organs, cells, and some foods. The word is more precise than “frozen,” since cryogenic temperatures are substantially colder than those used in ordinary refrigeration and often involve substances such as liquid nitrogen. In phrases such as “cryogenically frozen” and “cryogenically stored,” it emphasizes the use of controlled ultralow-temperature conditions. The term is formal and technical, and its use can imply both the practical benefits of long-term preservation and the considerable equipment and safety requirements associated with handling materials at such temperatures.
adverbIn a way involving extremely low temperatures, typically below about −150 °C, as used in the freezing, storage, or preservation of materials and biological specimens.
- At extremely low temperatures or by means of cryogenic techniques.
"The delicate tissue samples were cryogenically frozen for long-term storage."
"The vaccine was cryogenically frozen before being transported."
"The museum keeps fragile biological samples cryogenically preserved in liquid nitrogen."
From the Greek for “frost” and “producing,” this word describes the ultralow-temperature technology that keeps cells, tissues, and food stable for long periods.

Where does cryogenically come from?
The word belongs to the scientific family built from Greek kryos, meaning “frost” or “cold,” and a generating element related to Greek -genes, meaning “producing.” The adjective cryogenic and the noun cryogenics developed from this combination during the modern scientific use of low-temperature physics. The adverb cryogenically was formed in the usual English way with the suffix -ically. Related English terms include cryogen, cryoscopy, and cryoscopy’s associated field of study.
How cryogenically is actually used
This is technical terminology used chiefly in science, medicine, food preservation, and industry. It is formal and more specific than simply “frozen,” usually implying temperatures far below ordinary refrigeration.
