cryogenic vials for liquid nitrogen
Cryogenic vials for liquid nitrogen represent essential laboratory equipment designed specifically for the long-term storage and preservation of biological samples at ultra-low temperatures. These specialized containers are engineered with advanced materials that can withstand extreme cold conditions, typically maintaining structural integrity at temperatures as low as -196°C. The vials feature a secure threaded cap system with silicone gaskets that ensures an airtight seal, preventing sample contamination and nitrogen leakage. Manufactured from medical-grade polypropylene, these vials demonstrate exceptional chemical resistance and maintain sample integrity over extended periods. The innovative design includes external threading to minimize potential contamination risks and graduated markings for precise volume measurements. Many models incorporate a white writing surface for sample identification and tracking. The vials come in various sizes, typically ranging from 1.2ml to 5ml, accommodating different sample volumes and storage requirements. Their applications span across multiple fields, including cell culture storage, microorganism preservation, genetic material banking, and pharmaceutical research. The vials often feature a star-foot bottom design that promotes stable positioning in storage racks and prevents floating in liquid nitrogen, ensuring sample security and accessibility.
