Description
Short thread cap ND9 in pink with a white silicone / blue PTFE slit septum is intended for secure sealing of analytical sample vials in chromatography workflows. The slit septum supports needle entry and helps avoid vacuum build-up inside the vial when multiple injections are performed. Screw-cap geometry follows a crimp-cap design, which makes the closure suitable for robotic gripper arms on automated samplers. Soft elastomeric sealing promotes reliable penetration, while the PTFE face provides the sample-contact barrier. Pre-cut style septa in this product area cut only the silicone carrier in a Y-shape and leave the PTFE lamination intact, limiting concentration fluctuations that can occur with conventional slits. Closures of this short-thread type are offered as a cost-effective match to instrument-manufacturer quality levels. From manufacturer Altmann Analytik, the article is packed as 10×100 pieces, corresponding to 1000 caps per pack, for efficient stocking of ND9 short-thread vial lines in high-throughput laboratories.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about ND9 Short Thread Cap, pink
What is this article?
ND9 Short Thread Cap, pink 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.
