cell culture cryogenic tubes
Cell culture cryogenic tubes are essential laboratory tools designed for the long-term storage and preservation of biological samples at ultra-low temperatures. These specialized containers are manufactured with high-quality, medical-grade polypropylene that ensures exceptional durability and chemical resistance. The tubes feature a secure screw cap system with silicone gaskets that creates an airtight, leak-proof seal, protecting valuable samples from contamination and evaporation. Available in various sizes typically ranging from 1.2ml to 5ml, these tubes are specifically engineered to withstand temperatures as low as -196°C in liquid nitrogen storage while maintaining structural integrity. Each tube incorporates a frosted writing surface for sample identification and tracking, complemented by permanent graduations for accurate volume measurement. The tubes are sterile, DNase/RNase-free, and non-pyrogenic, making them ideal for storing sensitive biological materials including cell lines, bacteria, blood components, and genetic material. Advanced manufacturing processes ensure consistent wall thickness and superior clarity for sample visibility. The tubes are compatible with standard cryogenic storage systems and racks, facilitating organized storage and efficient sample management in laboratory settings.
