Description
Crimp cap ND20 aluminium, plain rolled, with a 3,0 mm silicone white septum and silver aluminium foil provides a dependable seal for analytical vials in laboratory headspace and related GC applications. The septum is fully coated with silver aluminium foil and is temperature-resistant from −60 °C to 220 °C, supporting stable performance across common thermal conditions in sample handling. Plain-rolled aluminium construction pairs with the soft foil-backed silicone for straightforward crimping and needle access on ND20 necks. This product from manufacturer Altmann Analytik is frequently employed on PerkinElmer instruments and is positioned as an alternative to selected Finneran references used in similar setups. Packed as 10×100 pieces within a total of 1000 pieces, the format suits high-throughput laboratories that prefer organised multipacks for stock control. The combination of plain-rolled aluminium and silver-foil silicone septum supports consistent sealing when preparing samples for routine chromatographic analysis.

Questions about ND20 Al crimp seal, blank roll., 3,0mm, 10 x 100 pc
What is this article?
ND20 Al crimp seal, blank roll., 3,0mm, 10 x 100 pc 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.
