Description
PE cap N20-DIN-L, clear is a polyethylene closure designed for roll-rim bottles with a flat DIN crimp neck N 20. The transparent open-top (holed) design supports secure sealing in chromatography and general laboratory sample handling while allowing access through the aperture when a matching septum is used. Manufactured from PE, the cap combines light weight with chemical resistance suitable for routine analytical workflows. This N 20 DIN-L style fits standard flat DIN roll-rim geometry and is supplied transparent for easy visual checks of the seal area. Offered from manufacturer Macherey-Nagel in practical laboratory packaging, the article is intended as chromatography accessory hardware for vial and bottle systems that require a reliable PE crimp-style cap. Each pack contains 100 pieces, supporting efficient stocking of sample-prep and storage lines. Use alongside compatible N 20 septa and bottles where a clear PE open-top cap is specified for method or workflow consistency.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about PE-Cap N20-DIN-H, tr
What is this article?
PE-Cap N20-DIN-H, tr 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.
