"Liquid nitrogen cryosurgery with a cryogun is the coldest (-196º C), most effective, and most versatile cryosurgical technique available. Using liquid nitrogen equipment like a cryogun is much colder and therefore more effective than applying LN2 with a swab (-20º C), nitrous oxide (-75º C), and disposable cold sprays (-55º C to -70º C).

Typically, a sample is plunged into liquid nitrogen or into liquid ethane or liquid propane in a container cooled by liquid nitrogen. The ultimate objective is to freeze the specimen so rapidly (at 10 4 to 10 6 K per second) that ice crystals are unable to form, or are prevented from growing big enough to cause damage to the specimen's ...
Medical cryotherapy gun with liquid nitrogen. In medical applications, spray cans containing dimethyl ether [4] or tetrafluoroethane may also be used to freeze and destroy tissue, for removal of warts and skin tags, or other uses in cryosurgery. Liquified petroleum gas including propane and butane is sometimes used.
The skeleton can also be put on an automatic timer that turns its glowing eyes on for six hours each day — handy if you only want them to light up at night. Once he was put together, I loved how ...

[10] Bullous pemphigoid is a condition that causes itchy blisters over the body that can mimic frostbite. [18] It does not require exposure to cold to develop.
