Understanding Liquid Nitrogen Spray
Liquid nitrogen spray is nitrogen gas cooled below its boiling point (-196°C), turning it into a cryogenic liquid that evaporates quickly upon exposure to room temperature. It is primarily used for rapid freezing due to its extremely low temperature. The spray application allows for precise treatment of small areas, especially in medical and cosmetic fields.
Unlike liquid nitrogen in bulk, sprays come in controlled delivery devices that ensure safety and ease of use. These devices vary from handheld cryosurgical instruments to larger industrial sprayers.
