Reliable Cryogenic Sample PreservationEngineered to withstand extreme temperatures ranging from -196C to +121C, these 3.0ml internally threaded cryogenic storage tubes ensure optimal sample protection during freezing, thawing, and transportation. The leak-proof design, complete with a silicone O-ring gasket, provides confidence that your valuable biological or chemical materials are stored securely.
Effortless Sample IdentificationEach tube features a white printed writing area, supporting accurate sample labeling and organization within crowded laboratory freezers. Optional color-coded caps further enhance sample management by facilitating quick identification and reducing handling errors. The clear, natural polypropylene body allows for easy visual assessment of contents.
Sterilization Options for Contamination-Free StorageTo uphold stringent laboratory standards, these tubes are available sterileprocessed by gamma irradiation or autoclaving. This ensures DNase/RNase-free conditions, making the tubes suitable for sensitive molecular biology, clinical, or biobanking applications. Autoclavable tubes also provide the flexibility of in-house sterilization for repeated usage cycles.
FAQs of Internally Threaded 3.0ml Cryogenic Storage Tubes:
Q: How do I use the internally threaded 3.0ml cryogenic storage tubes for sample storage?
A: To use these tubes, simply transfer your liquid or biological sample into the tube (up to 3.0ml), secure the internally threaded cap with the silicone O-ring to ensure a leak-proof seal, and label the white printed marking area for identification. The tubes are suitable for manual handling and compatible with most standard cryogenic storage racks.
Q: What sterilization methods have been used to ensure tube purity?
A: These storage tubes are sterilized either by gamma irradiation or by autoclaving. Both methods provide a high level of sterility, ensuring the tubes remain free from DNase, RNase, and other contaminants, making them suitable for sensitive applications.
Q: When is it beneficial to use these cryogenic tubes over other types of storage tubes?
A: These tubes are ideal when you require leak-proof, contamination-free storage of samples at very low temperatures (down to -196C) and need secure sample identification. They are specifically designed for cryogenic applications, providing a robust seal and resistance to pressure up to 95kPa, which makes them superior for critical cryopreservation needs.
Q: Where are these cryogenic storage tubes manufactured and supplied?
A: The tubes are designed, exported, imported, manufactured, supplied, and traded by companies based in India. They are distributed worldwide to various laboratories, research centers, and clinical facilities.
Q: What materials are used in the construction of these tubes and their caps?
A: These tubes are made from high-quality virgin polypropylene, ensuring chemical resistance and durability. The screw cap is also crafted from polypropylene and features a silicone rubber O-ring to create a tight, leak-proof seal that withstands repeated freezing and thawing cycles.
Q: How does the white printed marking area benefit sample identification?
A: The dedicated white printed writing area on each tube enables clear and lasting sample labeling, which is crucial for accurate record-keeping and quick sample retrieval. It prevents label smudging and ensures that important information about the sample remains legible, even after extended storage.
Q: What are the handling and storage advantages of the internally threaded design?
A: The internally threaded design minimizes the risk of cross-contamination during opening and closing, and it prevents accidental unscrewing. Combined with the leak-proof cap, this design feature optimizes sample security during cryogenic storage and transport.
