Description
Crimp cap ND20 aluminium headspace with a 3,2 mm silicone white/PTFE beige septum is a colourless sealing solution intended for critical headspace analyses. Pure ultra-clean septa are fully PTFE-coated and temperature-resistant from −60 °C to 200 °C, while the soft construction supports easy needle penetration during automated or manual sampling. The white/beige septum profile corresponds to the Agilent HT septum style, helping laboratories align consumables with established instrument methods. Supplied from manufacturer Altmann Analytik in a 10×100 multipack (1000 pieces total), this cap is suited to PerkinElmer and other headspace platforms that use ND20 aluminium crimp closures. It is offered as an alternative to selected Agilent, National Scientific, Wheaton, Finneran and VWR article references listed for comparable applications. Fully PTFE-faced silicone combines chemical resistance at the sample interface with a soft core for reliable piercing, making the cap a practical choice for routine and demanding headspace GC workflows.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about ND20 Al Headspace crimp seal, 3,2mm, 10 x 100 pc
What is this article?
ND20 Al Headspace crimp seal, 3,2mm, 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.
