11mm Crimp Top Autosampler Vial for GC and HPLC. Vials have a 40% larger opening than standard opening aluminum seal vials, manufactured of Clear or Amber borosilicate glass. The standard 12x32mm profile is compatible with 11mm aluminum seal closures. The precision-shaped bottleneck can improve the processing capacity of the autosampler. In order to ensure good function, it can be slit in advance to facilitate needle penetration, designed for single injection or short sampling cycle, and especially suitable for liquid chromatography.
