Description
Septa Ø 8 mm, thickness 1,3 mm, hardness 60° are laminated sealing discs for ND8 autosampler vials, built as natural rubber orange-red with a transparent TEF face. The 8 mm diameter and 1,3 mm thickness at hardness 60° provide a robust, resealable interface for repeated needle entry in chromatographic sample introduction. The natural rubber body supports elasticity and sealing force, while the TEF contact layer offers chemical resistance toward many analytical solvents used in GC and HPLC sample preparation. These ND8 septa are intended for laboratories that need a thicker, firmer liner than ultra-thin films when closing screw-cap vials for storage, transport, or autosampler operation. Available from manufacturer ROTH SELECTION, the product is packed as 1000 pc(s) with a total weight of 0,083 kg, suited to continuous analytical throughput. Within the autosampler vials and sample-bottle consumables range, the defined geometry and dual-layer construction help maintain consistent vial closure performance across routine series.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Septa Ø 8 mm, thickn. 1.3 mm, hard. 60°
What is this article?
Septa Ø 8 mm, thickn. 1.3 mm, hard. 60° is the article on this page. Luminix Health distributes Carl Roth 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.
Which category should I open next?
