Product Description
Autosampler runs that need multiple injections from one vial demand a septum that reseals after each puncture. These pre-assembled caps combine a polypropylene shell with a red PTFE/silicone septum, reducing handling and contamination while standing up to repeat sampling runs.
This listing is for Kimble catalog number 73813WH-13425: Polypropylene Screw Thread Caps, 13-425, White Slit, Case of 1,000. Caps are molded from polypropylene with the septum already installed, in standard or pre-slit configurations. Pre-slit septa ease needle penetration and reduce vacuum formation. Threads include 8-425, 9-425 and 13-425 for common autosampler vials, in black, blue or white. The caps are autoclavable. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
