Crystal clear, leak-proof cryovials with internal thread cap with blue insert, designed for biological sample storage to temperatures as low as −196 °C. For use only in gas phase of liquid nitrogen.

• Manufactured in cleanroom environment (Class 100,000)
• Free of RNase, DNase, DNA, PCR inhibitors, and pyrogens
• Sterile (gamma irradiated)
• Caps and vials co-molded from medical grade polypropylene, ensuring optimum seal to prevent leakage
• Large white marking area on vial
• Temperature range down to −196 °C

Designed for freezing samples in all cryopreservation applications, these vials feature an internal thread screw cap with blue insert design and an integrated O-ring to reduce the possibility of contamination. The caps and vials are made from the same batch of materials to ensure equal dilation coefficient, resulting in optimum sealing characteristics. These transparent, sterile, self standing vials allow easy observation and feature a large white writing area for easy marking.
