A cryo vial/freezing tube box is a durable, temperature-resistant storage solution used in laboratories to securely organize cryogenic vials or freezing tubes, which typically range from 1.0 to 5.0 ml in size. Made from materials like polycarbonate or polypropylene, these boxes can withstand ultra-low temperatures, including those in -80°C freezers or liquid nitrogen (-196°C). The boxes are stackable to maximize freezer space and include alphanumeric grids for easy labeling and sample tracking, making them ideal for storing biological materials like DNA, RNA, proteins, cells, or serum.
