Exceptional Temperature PerformanceThese cryogenic tubes function reliably from the ultra-low temperatures of liquid nitrogen storage at -196C to autoclaving at +121C. This adaptability ensures long-term sample integrity and safe processing through various laboratory workflows.
Leak-Proof and Easy Labeling DesignEach tube comes with an external-threaded cap and a silicone O-ring to create a secure, leak-proof seal. The transparent body and wide, frosted writing area allow convenient and clear labeling, streamlining sample identification and management.
High-Quality and Versatile MaterialsConstructed from medical-grade polypropylene, these tubes are both chemical resistant and autoclavable. The colored caps not only prevent sample mix-ups but also complement stringent lab color-coding protocols, enhancing user confidence and lab efficiency.
FAQs of 1.2ml Cryogenic Storage Tubes with External Threads:
Q: How should I use the 1.2ml Cryogenic Storage Tubes for cryopreservation?
A: To use, simply transfer your biological sample into the tube (up to 1.2ml), securely close the colored polypropylene cap with the silicone O-ring, and label the tube on its large frosted area. These tubes are designed for manual operation and are suitable for storage in ultra-low temperatures, including liquid nitrogen (-196C).
Q: What benefits do the external screw cap and silicone O-ring provide?
A: The external screw cap, alongside the silicone O-ring, creates a tight, leak-proof seal, ensuring your samples remain uncontaminated and protected from evaporation or leakage, even under extreme cryogenic conditions.
Q: When should I use the sterile versus non-sterile tubes?
A: Sterile tubes are recommended when working with sensitive biological samples or clinical applications to prevent contamination. Non-sterile variants are suitable for general laboratory storage where sterility is not critical.
Q: Where can I label these tubes for easy identification?
A: Each tube features a large frosted marking area that allows straightforward labeling with permanent markers or printed adhesive labels, helping maintain clear and organized sample tracking.
Q: What is the chemical and temperature resistance of these cryogenic tubes?
A: These tubes exhibit high chemical resistance and are autoclavable, withstanding a broad temperature range from -196C to +121C, ensuring they remain functional in both cryogenic and sterilization processes.
Q: What distinguishes these tubes from others on the market?
A: Features like the DNase/RNase-free medical-grade polypropylene, colored caps for coding, leak-proof seal, and a five-year shelf life make CST-1.2ML-ET an outstanding choice for reliability and ease in critical sample storage.
