WHEATON® LVI™ VIALS manufactured by DWK Life Science are converted from USP Type I borosilicate glass tubing with 300µL glass limited volume insert. Insert fused to vial has a slight flare at the top to provide a larger needle target area. 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.
