Certified vials are tested to confirm that the vials, cap, and septa have been properly manufactured, handled, and packaged for quality results. Snap-top vials come with snap caps that provide a secure seal to minimize evaporation, even with volatile samples. An audible click ensures a secure seal has been formed.

Glass vials are made of Type I, Class A 33-expansion borosilicate glass. High-recovery vials deliver maximum sample capacity (1.5 mL) with minimal residual volume (<4 µL)—use with bottom draw-port needles.

Please Note: Vials, caps, and septa formerly under the Kinesis brand have now been rebranded Cole-Parmer. All the same great features and specifications, just with a new and improved look.
