Description
Screw caps for sample tubes 9-425 with a white silicone/red P septum are polypropylene closures designed for chromatography vials that use the 9-425 thread. They provide a reliable seal for sample handling and injection workflows in analytical laboratories. The septum construction supports consistent needle penetration during sample introduction, while the Pre-Slit configuration features a pre-perforated septum to promote smooth, controlled injection and reduce coring risk. Suitable for routine vial work in chromatography accessories setups, these caps help maintain sample integrity from preparation through analysis. Supplied in a practical pack of 1000 pc(s) with a net weight of 0,300 kg, they are convenient for high-throughput environments that consume large numbers of closures. The product type is METRIA and originates from manufacturer Labbox. Use them wherever 9-425 threaded sample tubes or vials require a polypropylene screw closure with a silicone/P septum for liquid chromatography and related sample-introduction applications.

Questions about Screw cap for 9-425 vials with white silicone/PTFE septa, 10x100 pcs
What is this article?
Screw cap for 9-425 vials with white silicone/PTFE septa, 10x100 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.
