Description
PE cap N 20-abHS-L clear is a polyethylene crimp cap for roll-rim bottles with a beveled N 20 neck finish. The transparent open-top shell is combined with an unmounted beige butyl / grey PTFE septum of 1,3 mm thickness and 55° shore A hardness, intended for needle access in chromatography and sample-handling work. Packaged as 100 pieces, the closure supports routine sealing of N 20 crimp vials where a PTFE contact face and resilient butyl backing are preferred. From manufacturer Macherey-Nagel, this N 20 PE design suits analytical laboratories needing a clear PE housing with a centre hole for injection or withdrawal. The dual-layer septum helps maintain sample integrity during storage and transfer of organic or aqueous matrices on standard roll-rim glassware. Compatible with common N 20 beveled crimp necks, the unmounted septum format allows flexible assembly on matching bottles. Typical applications include GC and HPLC sample preparation, quality-control aliquots and general laboratory vial sealing where a non-sterile PE/butyl/PTFE combination is specified.
This article is part of Vial caps & septa, in Vials, caps & septa.

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