Description
Screw caps with bore hole, PP, ND9 are polypropylene closures intended for ND9 autosampler vials and related sample bottles in the laboratory. Each cap is supplied with a PTFE septum of 0,2 mm thickness and 53° hardness, giving a thin, chemically inert barrier over the bore opening for needle access during sampling workflows. The short description and manufacturer data specify screw caps with bore hole, PP, ND9, septum PTFE, 0,2 mm 53°, packed as 100 pc(s). These components sit in the labware range for laboratory glass, vessels, consumables and autosampler vials, where consistent neck finish and septum geometry matter for routine vial handling. Offered from manufacturer ROTH SELECTION, the set supports organised stocking of ND9-compatible screw closures beside matching vials. Pack weight is 0,025 kg, which keeps storage and bench handling straightforward for high-throughput benches. Polypropylene construction of the cap body pairs with the PTFE septum layer described above, matching the stated configuration without further grade claims. Use them wherever ND9 screw caps with a pre-bored opening and thin PTFE septum are required for sample bottles and autosampler vials in analytical and general laboratory practice.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Screw caps with bore hole, PP, ND9, Septum PTFE, 0.2 mm 53°, 100 unit(s)
What is this article?
Screw caps with bore hole, PP, ND9, Septum PTFE, 0.2 mm 53°, 100 unit(s) 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.
