The LVI Vials are 12 x 32 mm large opening vials with a sealed-in, limited volume insert. The manufacturing process precisely controls the depth and position of the insert relative to the bottom of the vial. This allows more consistent sample recovery from vial to vial and reduces the possibility of autosampler needle damage. The insert has a slight flare at the top, providing a larger needle target area, which prevents needle damage. The 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. All LVI Vials are supplied with a white ceramic "write-on" patch for easier sample identification and are compatible with all autosamplers that use 12 x 32 mm vials. Inserts and clear vials are manufactured from ASTM Type I, Class A borosilicate glass. Amber vials are manufactured from borosilicate glass. The LVI Vials are available with either an 11 mm crimp top finish, which can be used with all standard 11 mm aluminum seals, or with Wheaton's special 9 mm ABC screw thread.
