Secure and Sterile Cryogenic StorageThese 2.0ml cryogenic tubes are meticulously designed for the safe, long-term preservation of biological specimens. External screw threads paired with a silicone O-ring offer robust leak protection, even in extreme temperatures down to -196C. Gamma irradiation ensures sterility, making them suitable for sensitive research and clinical applications where contamination must be avoided.
User-Friendly FeaturesEfficient laboratory work is enabled by clearly marked graduations in 0.5ml increments, a white write-on panel for convenient labeling, and color-coded caps for swift identification. The high-quality polypropylene construction delivers lightweight durability, and each tube is carefully packaged in sterile bags or racks to guarantee readiness for immediate use.
FAQs of Pre-Sterilized 2.0ml Cryogenic Tubes with External Threads:
Q: How should I properly label and identify samples in these cryogenic tubes?
A: You can utilize the white write-on panel on each tube to note sample information with suitable laboratory markers. The availability of cap colors also supports easy differentiation between samples during storage or processing.
Q: What is the benefit of the external screw thread and silicone O-ring design?
A: The external screw thread, combined with a silicone rubber O-ring, results in an optimal leak-proof seal. This design provides robust protection against leaks or contamination, making the tubes reliable for cryogenic storage in both liquid nitrogen and mechanical freezers.
Q: When should I use pre-sterilized cryogenic tubes over non-sterile options?
A: Pre-sterilized cryogenic tubes, thanks to gamma irradiation, are ideal for sensitive biological samples that require maximum sterility and reduced risk of contaminationparticularly when storing or transporting high-value research or clinical materials.
Q: Where can these tubes be stored, and what temperature range can they withstand?
A: These tubes are engineered for storage in both liquid nitrogen (-196C) and mechanical freezers up to +121C. Their material and structural integrity are maintained across this temperature spectrum, ensuring sample safety during cryopreservation or autoclaving.
Q: What is the typical shelf life of these cryogenic tubes, and how are they packaged?
A: Each tube offers up to 5 years of shelf life from the date of manufacture. They are individually packed, either in sterile bags or in racks, ensuring they remain uncontaminated until first use.
Q: What processes must be followed before using these tubes for sample storage?
A: No additional preparation is needed since the tubes are pre-sterilized. Simply open the packaging, label the tube, fill it with your sample, and securely cap it before placing it into the chosen storage environment.
