CBS High Security Tubes are a unique fully secured system for storage of biological samples in liquid nitrogen. Once sealed, the CBS High Security tube eliminates concerns related to cross-contamination and sample degradation related to oxidation and evaporation. The tubes have been validated as leak-proof and shatter-proof in all cryogenic temperatures including temperatures as low as LN2 liquid phase. The tubes are compatible with standard racks, boxes (9x9 or 10x10), canes, manual and automated filling systems, and controlled rate freezers.
