Description
22 mm PE cap, transparent, with hole and a cap height of 8,4 mm is a polyethylene laboratory closure designed for vials and sample containers that require a pierced lid. The central opening supports needle or probe access while the PE construction offers a light, durable seal for general analytical and preparative work. Delivered as 10×100 pieces per pack (1000 pc(s) in total), the multipack format is practical for busy sample-prep benches, QC lines and research laboratories that consume large numbers of caps. Transparency allows rapid visual confirmation of fit and of any septum or liner beneath the cap. This version from manufacturer Altmann Analytik is specified for 22 mm necks with the lower 8,4 mm cap height, distinguishing it from taller PE variants in the same family. It is appropriate for routine chromatography vials, reagent vessels and similar labware where a simple PE snap-style or press-on lid with hole is needed. Match the neck finish and height to your vessel before use and handle according to standard laboratory practice for polyethylene consumables.

Questions about 22mm PE Cap, transparent, centre hole, cap height 8.4mm
What is this article?
22mm PE Cap, transparent, centre hole, cap height 8.4mm is the article on this page. Luminix Health distributes Altmann Analytik 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.
