Internal Thread Cryotube

◎ The cryotube is made of medical-grade polypropylene (PP) and are single-use laboratory consumables specially designed for biological sample storage.

◎ The internal-thread design provides stronger sealing for cryopreserved biological samples. Designed for sample storage in liquid nitrogen vapor phase, resistant to low temperatures down to -196°C.

◎ The tube cap is upgraded with a two-color injection molding process to ensure the safety of samples and laboratory personnel.

◎ The textured cap design facilitates screwing. The cap is equipped with multi-color insertable color codes for easy identification.

◎ Both the tube cap and tube body are made of PP raw materials of the same batch and model. Identical expansion coefficients ensure stable sealing performance.

◎ Barcodes and dual numeric codes enable digital sample management and easy identification, with a large marking area for convenient labeling.

◎ The rounded bottom design facilitates liquid concentration and reduces residue.

◎ Please operate strictly in accordance with laboratory standard operating procedures. No cracking will occur under standard operation.

◎ Available in general grade and PCR grade to meet different requirements. PCR-grade products are produced in a cleanroom, RNase-free, DNase-free, endotoxin-free and pyrogen-free, and sterilized by irradiation.
