The internally- or externally-threaded caps are co-molded with a thermoplastic elastomer (TPE) layer (which functions as an integrated o-ring) and are 95kPa certified to provide a 100% leak-proof seal. This proprietary molding process eliminates the risk of contamination, slippage and leakage associated with brands that use separate silicone o-rings. Color-coded cap inserts are available for segregating samples. Ideal for standardizing sample management in CoolRack CF-series temperature equalizing modules andCoolCell alcohol-free cell freezing containers. Packed 500 per case (10 x 50/pack).
