Description
Screw cap for sample vials with silicone/PTFE septum is a polypropylene closure intended for chromatography sample vials with 9-425 thread. The silicone/PTFE septum is fixed to the cap so that it does not detach when blunt tips are used, supporting secure sealing during sample handling and injection. These caps suit routine analytical workflows where reliable vial closure and septum retention are required. Offered in a pack of 100 pieces from manufacturer Labbox within the METRIA range, they are positioned as chromatography accessories for laboratories working with standard 9-425 threaded vials. Net weight is 0,030 kg. Polypropylene construction combined with a bonded silicone/PTFE septum helps maintain consistent closure behaviour in sample preparation and chromatographic analysis. Use them wherever dependable screw caps with an attached silicone/PTFE septum are needed for sample vials in the laboratory.
This article belongs on Vial caps & septa, in Vials, caps & septa.

Questions about Screw cap for vials with attached silicone/PTFE septa,
What is this article?
Screw cap for vials with attached silicone/PTFE septa, is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Vial caps & septa, inside Vials, caps & septa, in Chromatography equipment.
A vial cap and a septum have to match the vial neck: crimp, screw or snap, and the diameter. The septum material, PTFE/silicone or rubber, decides chemical resistance and how many times a needle can pierce it. A septum that sheds into the solvent becomes ghost peaks.
An autosampler vial is the small closed bottle a chromatograph picks up. The neck is crimp, screw or snap, and the cap and the septum have to be that neck. The septum is the part the needle pierces. A soft septum reseals. A septum that is wrong for the solvent swells or sheds particles into the sample. Inserts reduce the volume when the sample is scarce. The separation they feed is described with IUPAC names and PubChem data.
