These large-opening vials feature a sealed-in, limited-volume insert that allows more consisent sample recovery from vial to vial and reduces the possibility of autosampler needle damage.

Inserts and clear vials are manufactured from ASTM Type I, Class A borosilicate glass. Amber vials are manufactured from ASTM Type I, Class B borosilicate glass. All LVI™ vials include a white ceramic write-on patch for easier sample identification and are compatible with all autosamplers that use 12×32 mm vials. Convenience packs feature caps with 5 mil PTFE septa bonded to another material.

The insert has a slight flare at the top that provides a larger needle target and the manufacturing process precisely controls the depth and position of the insert relative to the bottom of the vial. LVI vials have a 300 µl capacity with a residual volume of only 4 µl, depending on the solvent, needle style, and depth adjustment of the autosampler.
