The cell cryopreservation tubes are made of transparent polymer material polypropylene (PP), which are manufactured through special processes. They can withstand extremely low temperatures, have a leak-proof seal, and are suitable for long-term cryogenic storage of cells and tissues.

• The tube body is made of polypropylene, which is uniformly transparent and resistant to extremely low temperatures. It can be repeatedly frozen and thawed.

• The tube body has clear markings and writing areas, which facilitate identification, observation and marking.

• The sealing cover is equipped with a silicone sealing gasket, which helps to better prevent liquid leakage.

• Withstands temperatures from -196°C to 121°C, and can be safely stored under liquid nitrogen vapor phase conditions.

• When freezing, the maximum liquid storage capacity is 80% of the maximum scale.

• The bottom of the bottle has an arc-shaped inner corner for easy cleaning, and the bottom is injection-molded with raw material information.

• The material has strong tolerance, low temperature resistance, UV resistance, and is not easy to crack.
