Description
9 mm PP short thread caps, blue, with hole and a 9 mm natural rubber red-orange septum are laboratory closures designed for secure sealing of compatible sample vials. Each cap is moulded from polypropylene and finished in blue for clear visual identification on the bench or in autosampler trays. The open-hole design works together with the fitted 9 mm natural rubber septum, allowing syringe access while maintaining a reliable seal around the needle path. Supplied as a matched cap-and-septum combination, the assembly supports routine sample handling, storage and chromatographic workflows where consistent thread geometry and septum performance matter. These components from manufacturer Altmann Analytik are packed in units of 1000 pc(s), making them practical for high-throughput laboratories that standardise on 9 mm short-thread vial systems. The red-orange natural rubber septum provides the elastomeric sealing surface specified for this configuration. Use the caps with matching 9 mm short-thread vials according to your method requirements. The straightforward colour coding, defined thread size and ready-fitted septum help streamline vial preparation and reduce handling steps in analytical and general laboratory environments.

Questions about 9 mm PP short thread cap, blue, w/ hole, Septum, natural rubber red-orange/TEF
What is this article?
9 mm PP short thread cap, blue, w/ hole, Septum, natural rubber red-orange/TEF is the article on this page. Luminix Health distributes Altmann Analytik 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.
