Disposable Flat Bottom 2ml Plastic Centrifuge Tubes Freezing Storage Tube with Screw Cover And Gasket

Freezing tubes, commonly referred to as cryovials, are specialized laboratory containers designed for the safe storage of biological samples at ultra-low temperatures, including in liquid nitrogen environments. These tubes are typically made from high-quality polypropylene (PP), which offers excellent chemical resistance, thermal stability, and durability at extreme temperatures (as low as -196 °C).

Cryovials come in various volumes, most commonly ranging from 1.0 mL to 5.0 mL, and are available in both internal and external thread formats. They are equipped with leak-proof screw caps, often with silicone O-rings or sealing gaskets, to prevent contamination and evaporation during storage.

Many freezing tubes are sterile, DNase/RNase-free, and come with printed graduation marks and writable surfaces for sample identification. They are widely used in biobanks, medical research, clinical labs, and pharmaceutical settings to store cells, DNA/RNA, serum, plasma, enzymes, and other biological specimens.
