Superior Sterility and Quality AssuranceEppendorf Conical Tubes are certified sterile, free of DNase, RNase, and Human DNA, ensuring maximum sample integrity for research and diagnostics. Each batch is traceable via individual lot IDs to support quality management systems and compliance in regulated environments.
Designed for Rigorous Laboratory ApplicationsWith high chemical, thermal, and mechanical resistance, these tubes withstand centrifugation forces up to 20,000 x g (50 mL) and 17,000 x g (15 mL). Suitable for autoclaving up to 121C, they maintain structural integrity under demanding laboratory protocols.
Versatile and Reliable Storage SolutionEppendorf Conical Tubes are compatible with freezer, refrigerator, and room temperature storage. Their leak-proof screw caps with integrated seals prevent contamination and evaporation, safeguarding precious samples during long-term storage or transport.
FAQs of Eppendorf Conical Tubes 15 mL and 50 mL:
Q: How are Eppendorf Conical Tubes sterilized and certified DNase, RNase, and Human DNA free?
A: These tubes undergo rigorous sterilization processes and quality controls, ensuring the absence of DNase, RNase, and Human DNA. Certification guarantees their suitability for sensitive molecular biology and cell culture applications.
Q: What is the maximum centrifugation resistance for 15 mL and 50 mL Eppendorf Conical Tubes?
A: The 15 mL tubes are resistant to centrifugation speeds up to 17,000 x g, while 50 mL tubes withstand up to 20,000 x g, making them ideal for high-speed separations in laboratory workflows.
Q: When can I use these conical tubes for autoclaving, and what is the recommended process?
A: These tubes are safe for autoclaving at 121C for up to 20 minutes. Always ensure that caps are loosely attached to avoid pressure build-up and tube deformation during the sterilization process.
Q: Where can I store Eppendorf Conical Tubes, and what is their shelf life?
A: You can store these tubes in freezers, refrigerators, or at room temperature. Each tube is guaranteed to maintain sterility and functionality for up to five years, provided storage guidelines are followed.
Q: What packaging options are available for these Eppendorf tubes?
A: Eppendorf Conical Tubes are available in rack-packed, bulk-packed, or individual packs, giving users flexibility based on their workflow and storage requirements.
Q: How does the integrated screw cap benefit sample handling and storage?
A: The screw cap with an integrated seal offers a leak-proof closure, preventing sample loss and contamination. Its design simplifies secure sealing and ensures the tubes remain tightly closed during centrifugation or transport.
Q: What are the main uses for these tubes in laboratory settings?
A: Eppendorf Conical Tubes are widely used for centrifugation, sample storage, and mixing. Their high clarity allows for easy visual inspection, and precise graduations support accurate measurement and aliquoting of samples.
