What is Freezing Tubes

Freezing tubes are laboratory equipment used to store and preserve biological samples at low temperatures, typically in a liquid nitrogen (-196°C) or dry ice (-78°C) bath. They are commonly used in research, medical, and industrial settings to preserve samples such as blood, cells, DNA, and enzymes for later analysis or use. Samples can be stored in various types of tubes, including cryovials, cryotubes, and cryopreservation straws.

Freezing Tubes Precautions for use

There are several precautions to keep in mind when using freezing tubes:
Always wear appropriate personal protective equipment (PPE) such as gloves, lab coats, and safety glasses to protect yourself from potential hazards.
Handle the freezing tubes and liquid nitrogen with care to avoid spilling or splashing, which can cause severe burns.
Do not overfill the tubes with liquid nitrogen, as this can cause the tubes to break or burst.
Keep the freezing tubes and liquid nitrogen away from heat sources and open flames.
Label the tubes clearly with the sample name, date, and any other relevant information to avoid mix-ups or errors.
Keep the freezing tubes in a secure and well-ventilated area to avoid accidental exposure to the liquid nitrogen.
Always monitor the level of liquid nitrogen in the container, as well as the temperature of the sample.
Follow the instructions provided by the manufacturer when using freezing tubes and liquid nitrogen.
Use appropriate thawing methods to avoid any damage to the samples.
Regularly check the freezing tubes for any signs of cracking or damage and replace them if needed.
