LCMS certified vials are manufactured using a process that reduces surface activity, improving analytical quantification and minimizing pH shifts in the samples. Surface metals such as sodium and boron that can contaminate samples and interfere with trace analysis are effectively removed. Screw vials feature 9-mm short thread with a unique thread design that allows you to screw on the caps and still use them in a robotic autosampler. The thread sits much higher on the vial allowing space between the bottom of the thread and the shoulder of the vial.

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.
