The 1.8 mL externally threaded cryo tubes with round base do not accommodate cap inserts because the tube and cap have the same external diameter and are designed to fit in metal ""canes"" used for holding individual tubes in a Dewar. Olympus cryovials are suitable for storage of cell cultures, tissue samples, microbiological samples (e.g. viruses, bacteria, yeast and other fungi, spores), material of human or animal origin, such as blood, serum and sperm as well as antibodies, RNA, DNA and protein samples. Dimensions (cap on): 42mm x 12mm
Olympus Plastics cryogenic storage tubes are ideal for vapor-phase liquid nitrogen freezing. All tubes feature a white writing area and black 100ul graduation marks and internal or external thread tube options are available. Internal thread tubes have a silicone rubber o-ring for a secure, leak-proof seal. External thread tubes have a lip seal feature so no o-ring is necessary. Round or self-standing star grip bases are available. Cap inserts in a variety of 10 different colors are available for color coding.
