Description
N 20 PE cap for roll-rim bottles with beveled crimp neck is a transparent, open-hole polyethylene closure equipped with a natural rubber / TEF colourless septum. Designed for N 20 crimp-neck bottles that use an abgeschrägt (beveled) roll rim, it provides a practical sealing option for laboratory sample handling. Septum hardness is 45° Shore A and septum thickness is 1,3 mm, dimensions suited to standard piercing and resealing steps in analytical workflows.
This article is part of Vial caps & septa, in Vials, caps & septa.
Supplied in packs of 100 pieces, the clear PE cap with centre hole allows visual checks of the septum and vial contents while remaining compatible with beveled N 20 roll-rim geometry. The natural rubber/TEF liner combination is a familiar choice for many routine laboratory sealing applications on crimp-style bottles. This PE cap from manufacturer Macherey-Nagel addresses laboratories that standardise on N 20 beveled crimp necks and need a transparent, holed cap with defined septum hardness and thickness. The open-hole design supports needle access through the septum without removing the cap, which is useful during sample preparation, aliquoting and instrumental introduction steps where repeated access to the vial headspace or liquid is required.

Questions about PE-Cap N20-bevT-H, tr, NR or/TEF,45°,1.3
What is this article?
PE-Cap N20-bevT-H, tr, NR or/TEF,45°,1.3 is the article on this page. Luminix Health distributes Macherey-Nagel 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.
