CryoClear™ cryogenic vials provide biological sample storage in temperatures as low as -196°C. CryoClear vials feature a screw cap that is co-molded with thermoplastic elastomer. This process prevents the risk of sample contamination. The CryoClear vials are certified 95kPA to provide a 100% leak-proof seal. Each production lot is certified by an independent laboratory to be free of human DNA, DNase, RNase, pyrogens, and ATP. Each vial is printed with a unique 128-format barcode for automated data collection, accurate sample inventory, and to hide the identity of the sample.
