These Wheaton LVI Vials are 12 x 32 mm large opening vials with a sealed-in, limited volume insert.  The depth and position of the insert relative to the bottom of the vial is precisely controlled during the manufacturing process, allowing more consistent sample recovery from vial to vial, and reducing the possibility of autosampler needle damage.  The insert has a slight flare at the top, providing a larger needle target area, which also prevents needle damage.  Inserts and clear vials are manufactured from ASTM Type 1, Class A borosilicate glass.  Amber vials are manufactured from borosilicate glass.  Available with an 11 mm crimp top finish, which can be used with all standard 11 mm aluminum seals.
