Cup 2 ml: CynKen 20pcs Graduated Plastic Cryovial Tubes – Self-Standing Cryogenic Vials with Caps
These polypropylene cryogenic vials demonstrate exceptional performance in ultra-low temperature laboratory environments, maintaining structural integrity at -180°C (-356°F) without brittleness or cracking. The pharmaceutical-grade PP material exhibits superior chemical resistance against common laboratory solvents, acids, and biological specimens. Precision molding ensures consistent 2ml capacity with clearly etched graduation marks for accurate sample measurement and documentation. The self-standing conical bottom design prevents rolling and provides optimal stability on laboratory benches and in freezer racks. Leak-proof sealing mechanisms protect valuable samples from contamination while allowing easy access during thaw cycles. Quality control testing confirms dimensional accuracy within ±0.02ml tolerance, meeting stringent laboratory standards for sample storage and retrieval protocols in research and clinical applications.

⚖Competitive Analysis
Cryogenic Storage Protocol
Sample Preparation
Fill vials leaving 10% headspace for thermal expansion. Label with cryogenic-compatible markers before freezing.
Gradual Cooling
Pre-cool at -20°C for 30 minutes, then -80°C for 1 hour before liquid nitrogen immersion.
Safe Handling
Use insulated forceps for transfer. Allow gradual thawing at room temperature to prevent thermal shock.
Laboratory Technician FAQ
What sample types are compatible with these vials?
Cell cultures, DNA/RNA samples, protein solutions, serum, plasma, and other biological specimens requiring ultra-low temperature preservation.
How many freeze-thaw cycles can these vials withstand?
PP construction allows 20+ freeze-thaw cycles without structural degradation, maintaining seal integrity throughout repeated use.
Are these vials autoclavable for sterilization?
Yes, polypropylene withstands standard autoclave cycles at 121°C for 15-20 minutes without deformation or chemical leaching.
What storage rack systems are compatible?
Standard 2ml cryogenic tube racks, automated storage systems, and liquid nitrogen storage boxes with appropriate grid dimensions.

Laboratory Professional Review
Dr. Jennifer K. – Research Scientist
“These PP cryogenic vials exceeded expectations in our stem cell research facility. We’ve processed over 500 samples without a single seal failure or cracking incident. The self-standing design saves considerable bench space in our crowded lab environment. Temperature cycling from liquid nitrogen to room temperature shows no structural degradation after 6 months of use. The graduated markings remain clearly visible even after multiple freeze-thaw cycles. Definitely recommend for high-volume laboratory applications.”
