nitrogen freeze

Nitrogen freeze involves cooling a substance rapidly with very cold liquid nitrogen, which has a boiling point of -196°C (-321°F). This process causes the material to freeze swiftly, often preserving its structure and properties. It’s commonly used in medical procedures, such as removing skin lesions, or in industrial settings for preserving biological samples. The extreme cold causes molecular activity to cease quickly, creating a solid state without the gradual freezing that can damage tissues. Overall, nitrogen freeze is a precise and effective method to rapidly halt biological or material processes by lowering temperatures well below freezing.
