cryovials for liquid nitrogen storage
Cryovials for liquid nitrogen storage represent essential laboratory equipment designed specifically for the preservation of biological materials at ultra-low temperatures. These specialized containers are engineered with high-quality polypropylene materials that maintain structural integrity in extreme cold conditions, typically at temperatures as low as -196°C. The vials feature a secure threaded cap design with silicone gaskets that ensures an airtight seal, preventing sample contamination and nitrogen seepage. Each vial typically includes graduation marks for precise volume measurement and a white writing area for sample identification. Modern cryovials incorporate innovative features such as star-foot bottoms for enhanced stability during storage and handling, internal threading to minimize potential contamination risks, and specialized cap designs that allow for single-handed operation. These vials are available in various sizes, commonly ranging from 1.2ml to 5ml, to accommodate different sample volumes. The design includes considerations for automation compatibility, making them suitable for high-throughput laboratory operations. Their durability ensures multiple freeze-thaw cycles without compromising the structural integrity or seal quality.
