Description
neochrom® Septum ND8 virgin PTFE is an unmounted septum intended for ND8 screw-thread vials used in chromatography and routine laboratory sample handling. Made from virgin PTFE, it offers a chemically resistant sealing surface for small-volume sample containers where solvent compatibility and clean closure performance matter. The ND8 format matches standard screw-thread bottles widely employed in analytical chemistry, quality control and sample preparation. These septa are supplied unmounted, so they can be paired with compatible ND8 screw caps according to method needs. A pack of 1000 pieces supports high-throughput work and economical stocking of consumables. Products in the neochrom® line from manufacturer neolab - Labor are aimed at everyday laboratory use with common vial systems. Virgin PTFE construction suits many organic solvents and reagents encountered in GC and HPLC sample introduction. Suitable for autosampler and manual sampling setups that specify ND8 closures, and for laboratories that prefer to select septum and cap components separately for flexible method configuration.
This article belongs on Vial caps & septa, in Vials, caps & septa.

Questions about neochrom® Septum ND8 PTFE virginal, 1000 Stck./Pack
What is this article?
neochrom® Septum ND8 PTFE virginal, 1000 Stck./Pack is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Vial caps & septa, inside Vials, caps & septa, in Chromatographie.
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.
