Superior Sealing and SterilizationEach tube includes a silicon O-ring and external threaded screw cap, guaranteeing reliable leak-proof sealing during cryogenic storage and centrifugation. Gamma irradiation or electron beam sterilization ensures each tube is free of contaminants, making them immediately ready for research or clinical use.
Versatile and Durable StorageDesigned to hold up to 3.8ml, these tubes accommodate a range of biological samples, including cells, tissues, blood, and nucleic acids. Their polypropylene construction provides exceptional resistance to a wide range of laboratory chemicals and thermal extremes, ensuring long-term integrity of stored specimens.
Efficient Sample IdentificationFrosted marking panels on each tube allow for clear and durable labeling. Assorted cap colors facilitate sample management and organization, particularly in high-throughput laboratory environments.
FAQs of Silicon O-Ring Equipped 3.8ml Cryogenic Storage Tubes:
Q: How do the silicon O-ring and screw cap enhance leak-proof performance?
A: The silicon O-ring creates a secure, airtight seal when used with the external threaded screw cap, effectively preventing leaks and minimizing contamination risks even during centrifugation or extreme temperature changes.
Q: What types of samples can be safely stored in these cryogenic tubes?
A: These tubes are suitable for a variety of biological samples, including cells, tissues, blood, serum, DNA, RNA, and commonly used laboratory reagents, making them highly versatile across research and clinical settings.
Q: When should these tubes be used for sample storage?
A: They are ideal whenever samples require cryogenic storage, such as in long-term biobanking, preserving specimens at temperatures ranging from -196C to +121C, or during laboratory workflows involving high-speed centrifugation up to 17,000 x g.
Q: Where can these cryogenic tubes be utilized within the laboratory?
A: These tubes are compatible with standard laboratory freezers, cryogenic storage systems, and centrifuges, making them suitable for use in research laboratories, hospitals, biorepositories, and diagnostic facilities.
Q: What is the recommended process for labeling and organizing samples?
A: Each tube features a frosted marking area designed for writing with laboratory-grade markers. Assorted cap colors help quickly identify and categorize different samples or batches for streamlined workflow.
Q: What benefits does the high chemical resistance offer?
A: Thanks to their polypropylene construction, the tubes maintain integrity and seal even in the presence of common laboratory chemicals, ensuring that sample quality is preserved and minimizing the risk of tube degradation over time.
Q: How does the sterilization method (gamma or electron beam) affect product safety?
A: Both gamma irradiation and electron beam sterilization guarantee that each tube arrives free from biological contaminants, reducing the risk of cell culture or sample compromise and supporting high standards of laboratory safety and research validity.
