Description
Screw caps with bore hole manufactured from polypropylene (PP) for ND8 autosampler vials provide a practical closure solution for chromatographic and general laboratory sampling. The integrated septum is natural rubber/TEF, 1,3 mm thick at 60°, offering a resilient resealing surface suited to needle puncture during automated or manual injection. The bored centre allows direct access to the sample while the screw thread secures the cap on matching ND8 neck finishes. Packaged as 100 pc(s) and available from manufacturer ROTH SELECTION, these caps support standardised vial workflows in analytical chemistry, quality control and routine sample handling. Pack weight is approximately 0,050 kg, facilitating easy storage and bench use. They form part of the laboratory consumables range for autosampler vials and sample bottles, where a natural rubber/TEF septum combination is required for sealing performance and chemical compatibility with typical mobile phases and sample matrices. Pair with compatible ND8 vials to ensure a consistent seal throughout preparation, storage and analysis.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Screw caps with bore hole, PP, ND8, Septum Natural rubber/TEF, 1.3 mm 60°
What is this article?
Screw caps with bore hole, PP, ND8, Septum Natural rubber/TEF, 1.3 mm 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.
