Description
ND9 PE cap in red, fitted with a slit silicone white/PTFE red septum, is designed for use with 96-well block inserts in high-throughput chromatographic sample preparation. The polyethylene short-thread closure combines a coloured PE shell with a pre-slit silicone/PTFE laminate so needles can penetrate consistently while the PTFE face limits analyte interaction at the sample interface. Intended for block-insert formats rather than single-vial racks, the red ND9 geometry supports organised handling across multi-well workflows in GC and HPLC environments. The slit septum configuration facilitates injection access and helps reduce vacuum build-up compared with fully closed laminates when repeated sampling is required within a run. This product from manufacturer Altmann Analytik is packed 960 pieces per unit and is offered as an alternative to corresponding Agilent (5188-5322), Waters (58959) and Chromacol ND9 block-insert closures. It suits laboratories standardising red PE short-thread caps on 96-position inserts where clear visual coding and reliable silicone/PTFE sealing are required.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about ND9 PE cap, red, for 96er Block-ins.
What is this article?
ND9 PE cap, red, for 96er Block-ins. 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.
