1.The cryopreservation tube is made of medical polypropylene, which can withstand low temperatures to -196°C.

2.The tube cap is equipped with a silicone pad to prevent liquid leakage, and it can ensure the tightness even at the lowest storage temperature, and ultimately ensure the safety of the sample in the tube.

3.The cap pattern is easy to rotate the cap, and the cap is equipped with a variety of embeddable color codes for easy identification.

4.The external rotating cryotube is designed for freezing samples, and the screw cap of the external rotating cap can reduce the chance of contamination when handling samples.

5.The cap and the body are made of PP raw materials of the same batch and model, so the same expansion coefficient ensures sealing.

6.Bar codes and double-digit codes are used for sample digital management and easy identification, and a large marking area is convenient for writing.

7.The round bottom design facilitates pouring of liquid and reduces residue.

8.The products are produced in the purification workshop, RNase-free, DNase-free, endotoxin-free, pyrogen-free, and sterilized by gamma irradiation.
