Leak-Proof Cryogenic AssuranceThis storage tube is equipped with an advanced internal thread screw cap and silicone O-ring, guaranteeing reliable leak-proof performance even in extreme cold and high-pressure environments. Whether working in clinical, laboratory, or research settings, the tube sustains sample integrity during cryogenic storage and transportation.
Sterility and Material QualityEach tube is gamma-irradiated for sterility and manufactured from virgin medical grade polypropylene (PP), enforcing DNase/RNase free and autoclavable standards. This ensures the safe containment of sensitive biological specimens and minimizes cross-contamination risks.
FAQs of 3.8ml Cryogenic Storage Tube With Internal Threads:
Q: How is the 3.8ml Cryogenic Storage Tube best used for storing biological samples?
A: The tube is optimized for cryogenic storage in the vapor phase of liquid nitrogen, maintaining sample stability at temperatures ranging from -196C to +121C. Its leak-proof design and sterile, autoclavable construction make it ideal for preserving the integrity of biological specimens.
Q: What makes the internal thread screw cap with silicone O-ring beneficial for cryogenic storage?
A: The internal thread screw cap, paired with a silicone O-ring, ensures a tight, leak-proof seal. This is crucial for preventing contamination and accidental spillage during harsh cryogenic storage and pressure changes, safeguarding sample integrity.
Q: Where can this tube be used in laboratory workflows?
A: This tube can be integrated into manual laboratory procedures where cryogenic storage is needed, such as sample collection, processing, long-term archiving, and transportation to research labs, clinics, or biotechnology facilities.
Q: What is the process for labeling these cryogenic tubes?
A: A frosted marking area is provided on each tube, allowing users to conveniently label and identify samples with markers or printed labels, facilitating efficient organization and traceability in storage environments.
Q: When should autoclaving be performed on these tubes?
A: Autoclave the tubes prior to sample usage if additional sterilization is desired or after use for decontamination. The virgin medical grade PP material ensures the tube remains intact and functional post-autoclaving.
Q: How do the printed graduations support sample accuracy?
A: Clear, easy-to-read graduations in 0.5 ml increments facilitate precise volume measurements and ensure accurate sample aliquoting, which is critical in molecular biology, clinical research, and analytical applications.
