Description
Headspace caps with bore hole, Al, ND20 are aluminium headspace crimp closures for laboratory vials with an ND20 neck finish. Each cap carries a Butyl/PTFE septum of 3,0 mm thickness and is intended for headspace and autosampler vial applications where a sealed aluminium crimp is required. The bore hole in the cap face leaves the septum free for needle access during headspace sampling or injection. Supplied in packs of 100 pieces, the product gives laboratories a convenient stock quantity for series work with ND20 headspace vials and sample bottles. This article comes from manufacturer ROTH SELECTION as part of its autosampler vial accessory range. The Butyl/PTFE septum type is the liner specified for this headspace-cap variant. Aluminium ND20 geometry matches standard crimp-neck headspace glassware of that size when used with appropriate crimping tools. Pack weight is 0,183 kg. These headspace caps with bore hole are described solely by material, neck finish, septum and pack size as given in the manufacturer data, for laboratories that specify Butyl/PTFE liners on ND20 aluminium headspace seals.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Headspace-caps with bore hole, Al, ND20, Septum Butyl/PTFE, 3,0 mm, 100 unit(s)
What is this article?
Headspace-caps with bore hole, Al, ND20, Septum Butyl/PTFE, 3,0 mm, 100 unit(s) is the article on this page. Luminix Health distributes Carl Roth 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.
