Enhanced Leak-Proof SecurityEach cryo tube features an internally threaded cap with a silicone O-ring, ensuring a leak-proof environment for cryopreservation and sample transport. This design is rigorously tested for performance in liquid nitrogen vapor phase storage, providing reliability and safety for critical biological applications.
User-Friendly Design for Accurate Sample ManagementGraduation marks at 0.5ml intervals and a frosted marking area allow for precise measurement and easy labeling. The transparent tube body and colored caps facilitate efficient sample identification and organization within busy laboratory environments.
FAQs of Internally Threaded 2.0ml Cryo Tubes with Round Bottom:
Q: How are these internally threaded cryo tubes used for biological sample storage?
A: These tubes securely hold biological samples for cryopreservation, laboratory storage, or clinical transport. The leak-proof, internally threaded design provides optimal sealing, while the round bottom shape aids in complete recovery of contents.
Q: What temperature range can the cryo tubes safely withstand?
A: The tubes are suitable for use in extreme temperatures from -196C to +121C, making them ideal for ultra-low temperature cryogenic storage and heat-based autoclave sterilization.
Q: When is it appropriate to use sterile versus non-sterile tubes?
A: Sterile tubes should be chosen for applications requiring aseptic conditions, such as clinical sample storage or sensitive molecular experiments. Non-sterile tubes are suitable for general laboratory use where sterility isnt crucial.
Q: Where can these cryo tubes be applied in the laboratory?
A: They are ideal for cryopreservation, routine sample storage, and clinical sample transportation in research, medical, and biotechnological laboratories. Their robust construction supports use in both manual and automated workflows.
Q: What process ensures the tubes are DNase/RNase and endotoxin free?
A: Manufactured from medical-grade polypropylene in controlled environments, the tubes undergo stringent quality tests to confirm DNase/RNase and endotoxin absence, protecting the integrity of stored biological material.
Q: How does the frosted marking area benefit sample identification?
A: The frosted area offers a writable surface, allowing researchers to label tubes directly using markers or labels. This reduces errors and simplifies tracking during storage and retrieval.
