Precision Engineering for Sample SecurityDesigned with an external threaded screw cap and silicone O-ring, these tubes provide exceptional leak-proof protection under pressure. Their robust structure ensures maximum safety and closure integrity for critical biological samples, even during extreme temperature shifts.
Versatile and Resistant for Laboratory DemandsManufactured using medical-grade virgin polypropylene, the cryogenic tubes resist most chemicals and solvents commonly used in laboratories. Compatible with storage in liquid nitrogen vapor phase and featuring a shelf life of up to five years, they guarantee reliable, long-term sample preservation.
User-Friendly Design and TraceabilityFor enhanced usability, each tube includes printed graduation marks, a self-standing conical bottom, and colored caps for instant content identification. With a specific labeling area, researchers can swiftly organize and retrieve samples, streamlining workflow and reducing errors.
FAQs of 3.0ml Cryogenic Storage Tube with External Threads:
Q: How can the 3.0ml Cryogenic Storage Tube be used for biological sample storage?
A: These tubes are designed for secure storage of biological samples at ultra-low temperatures. They maintain integrity in liquid nitrogen vapor phase, ensuring samples remain viable and uncontaminated during long-term freezing and thawing cycles.
Q: What benefits do colored caps and printed graduation markings provide?
A: Colored caps assist with quick sample recognition, while printed graduation markings enable precise volume measurement. Together, they improve organization and reduce potential identification errors in laboratory storage and handling.
Q: When should the tubes be used in liquid nitrogen storage?
A: The tubes are intended for use in the vapor phase of liquid nitrogen, not submerged in liquid phase, to prevent tube deformation or cap loosening. This ensures optimal sample preservation and safety during ultra-low temperature storage.
Q: Where can these tubes be effectively used within laboratory settings?
A: These cryogenic storage tubes are ideal for research and clinical laboratories involved in biobanking, molecular biology, and cell culture, where safe, reliable sample storage at ultra-low temperatures is essential.
Q: What process ensures the tubes are sterile and contamination-free?
A: Each tube is gamma-irradiated to achieve sterility, and is free from DNase and RNase, making it safe for sensitive biological applications requiring contamination-free conditions.
Q: How does the conical self-standing base improve laboratory workflow?
A: The conical self-standing base provides stability, allowing tubes to stand independently on flat surfaces. This feature simplifies sample loading, pipetting, and minimizes the risk of accidental spills.
Q: What is the advantage of the silicone O-ring in the external threaded cap?
A: The silicone O-ring enhances the leak-proof seal of the cap, ensuring closure integrity under pressure and during temperature fluctuations, thereby protecting sample quality and preventing contamination.
