Description
Screw cap for sample vials 9-425 with a pre-perforated silicone/PTFE septum is a polypropylene closure matched to vials that use the 9-425 thread. In the pre-slit configuration the septum is already perforated to support smooth needle passage and consistent injection performance during chromatographic sample introduction. The polypropylene cap body provides a durable, laboratory-ready housing, while the silicone/PTFE septum delivers a sealing interface suited to analytical workflows. These closures are intended for sample tubes and vials with 9-425 threading commonly found in chromatography sample preparation. Available as a pack of 100 pc(s) from manufacturer Labbox, the format fits method development, routine QC and smaller batch runs where controlled consumable quantities are preferred. Net weight is 0,030 kg. Classified as product type METRIA, the item belongs to chromatography accessories focused on reliable vial sealing and injection access.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Screw cap for 9-425 vials with white pre-slit silicone/PTFE septa, 100 pcs
What is this article?
Screw cap for 9-425 vials with white pre-slit silicone/PTFE septa, 100 pcs 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.
