LNC treatment requires only about one-thirds the time by CO2 snow or nitrous oxide system (Regular cryo gun) to achieve the appropriate degree of freezing because of the relative temperatures (-196 degrees C when compared with -79 degrees C).
Liquid nitrogen can be applied directly by spraying the gun.
It is convenient to arrange a freezing session on a specific day and can be treated on any number of patients on the same day. No form of anesthesia is required for freezing, it can be carried out single-handed and no scarring results.
Liquid nitrogen treatment can be done most conveniently and economically and usually arrange to have the container (cryo-can) filled at a local hospital, laboratory or even a factory,
Milk diary as liquid nitrogen now-a-days is widely used for many purposes and small quantities (350ml) works out at no cost!
