Spray containing propane, butane, and ethanol, for dental applications. Freeze spray (cold spray or vapocoolant) is a type of aerosol spray product containing a liquified gas used for rapidly cooling surfaces, in medical and industrial applications. It is usually sold in hand-held spray cans. It may consist of various substances, which produce ...
Cryogun used to spray liquid nitrogen. A common method of freezing lesions is by using liquid nitrogen as the cryogen. The liquid nitrogen may be applied to lesions using a variety of methods, such as dipping a cotton or synthetic material tipped applicator in liquid nitrogen and then directly applying the cryogen onto the lesion.

Liquid nitrogen has a boiling point of about −196 °C (−321 °F; 77 K). It is produced industrially by fractional distillation of liquid air. It is a colorless, mobile liquid whose viscosity is about one-tenth that of acetone (i.e. roughly one-thirtieth that of water at room temperature). Liquid nitrogen is widely used as a coolant.
Liquid nitrogen, freeze spray or compressed air cans can be improvised to cool memory modules, and thereby slow down the degradation of volatile memory. DIMM memory modules gradually lose data over time as they lose power, but do not immediately lose all data when power is lost. [2]
Flash freezing. In physics and chemistry, flash freezing is the process whereby objects are rapidly frozen. [1] This is done by subjecting them to cryogenic temperatures, or it can be done through direct contact with liquid nitrogen at −196 °C (−320.8 °F). It is commonly used in the food industry.
Cryotherapy, sometimes known as cold therapy, is the local or general use of low temperatures in medical therapy. Cryotherapy may be used to treat a variety of tissue lesions. [1] The most prominent use of the term refers to the surgical treatment, specifically known as cryosurgery or cryoablation. Cryosurgery is the application of extremely ...
Freeze-dried strawberries. Freeze drying, also known as lyophilization or cryodesiccation, is a low temperature dehydration process [1] that involves freezing the product and lowering pressure, thereby removing the ice by sublimation. [2] This is in contrast to dehydration by most conventional methods that evaporate water using heat.
Cryogenics technology using liquid nitrogen and CO 2 has been built into nightclub effect systems to create a chilling effect and white fog that can be illuminated with colored lights. Cryogenic cooling is used to cool the tool tip at the time of machining in manufacturing process. It increases the tool life.
