Please note that this product is "made to order". Therefore an order cannot be canceled or returned even if delivery times are longer! Borosilicate glass vial with 300μL glass limited volume insert. Residual volume of only 4 µL, depending on the solvent, needle style and depth adjustment of the autosampler. Limited Volume Insert is fused to vial which prevents needle damage. 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. Writing patch on all vials. Purchase vials and caps separately or together in convenience packs.Meer tonenMinder tonen
