Innovative closure technology. Unmatched performance.

The Thermo Scientific™ National Target™ DP™ 9mm C5000 series and the Thermo Scientific™ Chromacol™ K-Series vial closure systems are innovative, flexible and performance driven vial closure systems built on the Advance Vial Closure System (AVCS) technology platform.

Based on Advance Vial Closure System (AVCS) technology

Chromacol and National Target DP 9mm AVCS color closures help chromatographers achieve more reliable and efficient sample analysis. Designed to accommodate nearly all chromatography autosamplers fitted for 12 x 32cm vial trays, the Chromacol K-Series and National C5000 series closures effectively eliminate septa push-through and significantly enhance productivity and flexibility in the laboratory.


9mm Screw thread vial closure types

AVCS closures are offered in a larger assortment of cap colors and septum formulations than any other supplier providing unmatched flexibility in meeting laboratory needs. For easy visual identification of samples around the laboratory, select from a range of colors for use with clear, amber or plastic vials.


Features of 9mm Wide Opening, Integral Membrane and Solid Closures
  • Nearly eliminates septa push through due to AVCS technology
  • Increased sealing capability
  • Unlimited options in selecting the best septum for your instrument and applications
  • Cost efficient closure as current choices for resolving push through (bonded septa) become obsolete
  • Optimized ergonomics, fine texturing and evenly space ribbing for handling even with poorly fitting gloves

A wide opening vial deserves a wide opening closure, utilizing AVCS, providing greater area for injection needle penetration.

In addition to AVCS technology, the integral membrane provides a high value option for applications where the environment is more conducive to a polypropylene membrane.

AVCS technology provides maximum protection of samples during down to -80 °F.
