Description
Crimp caps with bore hole, Al, ND20 are aluminium crimp seals for ND20 neck-finish laboratory vials. This version is fitted with a Silicone/PTFE AGILENT HT septum of 3,25 mm thickness in a 45° arrangement, suited to autosampler vials and sample bottles in instrumental analysis. A central bore hole in the aluminium cap keeps the septum accessible for needle penetration during sample introduction. The pack comprises 100 pieces, supporting day-to-day sealing work in chromatography and related laboratory settings. Available from manufacturer ROTH SELECTION, the caps align with standard ND20 crimp-top vial systems used across many analytical platforms. The Silicone/PTFE AGILENT HT designation identifies the specific septum liner supplied with this article. Aluminium construction provides the mechanical shell for a conventional crimp closure on matching glassware. Pack weight is 0,171 kg. These ND20 crimp caps with bore hole form part of a focused selection of vial accessories for laboratories that standardise on aluminium crimp seals and the stated septum specification for routine sample handling.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Crimp caps with bore hole, Al, ND20, Septum Silic./PTFE AGILENT HT,3,25mm 45°
What is this article?
Crimp caps with bore hole, Al, ND20, Septum Silic./PTFE AGILENT HT,3,25mm 45° 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.
