EcoPure brand caps for chromatography vials offer an economical, very clean, contaminate-free closure designed to fit most 12 x 32mm (2ml) HPLC and GC vials.

Their proprietary one piece polymer blend and unique sealing cone assures the lightest puncture force and best sealing system for a low cost, single piece cap.  Since there is no split septa, the caps can be used for either analysis or for long term storage with no evaporative loss.  No septa means no failed samples due to septa dislodging into vial. And no silicone means no worries about potential unidentifiable peaks from silicone layer contaminants, especially using LC/MS.
