Snap Seal Vials

The Snap Seal vial has a patented neck design that simplifies vial and cap selections, and assures reliable use with autosamplers with robotic arms.
Snap Seal vials have more glass in the neck area that a Snap Ring vial, minimizing breakage during the decapping procedure. The neck design also provides for a tight seal using any liner thickness.
