Description
PE cap N20-DIN-L clear is a polyethylene closure for crimp-neck bottles with a flat DIN roll rim N 20, supplied as an open-hole cap with an unmounted septum. The septum combines beige butyl rubber with grey PTFE and is specified at 55° Shore A hardness with a septum thickness of 1,3 mm, supporting reliable sealing and sampling access in chromatography and general analytical sample handling. The transparent PE shell allows easy visual orientation during preparation of vials and bottles that use the N 20 DIN-L geometry. Designed for roll-rim bottles with a flat DIN crimp finish, this cap format is widely used where butyl/PTFE septa are preferred for chemical resistance and reseal behaviour. Offered from manufacturer Macherey-Nagel in packs of 100 pieces, the unmounted septum arrangement gives laboratories flexibility when assembling closures to match their workflow. Net and gross pack weight are both indicated at 0,17 kg in the source data, reflecting a compact bulk pack for routine stocking. This N 20 PE cap is a practical consumable for sample storage, transfer and instrumental analysis setups that require clear PE caps with butyl/PTFE septa.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about PE-Cap N20-DIN-H tr, Bu/PTFE 55° 1.3 na
What is this article?
PE-Cap N20-DIN-H tr, Bu/PTFE 55° 1.3 na 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.
