Cryogenic tubes, also known as freezing tubes, are essential laboratory consumables widely used for low-temperature preservation in biological, pharmaceutical, food, and other industries. Made from medical-grade polypropylene (PP), they can withstand temperatures as low as −196 °C in the vapor phase of liquid nitrogen. NEST cryogenic tubes are available in multiple formats, including standard tubes, 2D barcode tubes, and triple-code tubes, with options for regular box packaging or SBS format for automated systems. Manufactured with high-precision injection-stretch-blow molding and fully automated equipment, they are produced from top-quality, food-grade resins compliant with USP Class VI and pharmaceutical standards, containing significantly lower levels of trace element extractables than glass. Certified to ISO 13485 and ISO 9001, these tubes offer batch-to-batch stability, meet the highest quality standards, and are available in a variety of specifications to suit different applications. Some formats are also reusable and highly durable, helping to reduce waste, prevent leakage of harmful substances, and support environmentally friendly laboratory practices.
