Description
Short thread cap ND9 is a polypropylene closure designed for 9 mm vial necks in analytical sample handling. The blue PP short-thread body features a centre hole and is fitted with a 0,06 mm aluminium seal that is sealed by a transparent flat gasket, supporting reliable needle access during automated or manual sampling. Supplied in packs of 1000 pc(s), this configuration suits high-throughput chromatography workflows where consistent fit and seal integrity on ND9 short-thread vials are required. The aluminium sealing layer provides a defined barrier thickness of 0,06 mm for routine laboratory use. These caps from manufacturer Altmann Analytik are intended as consumable closures for laboratory sample vials and related analytical setups. The open-centre design allows penetration of the seal without removing the cap, which is typical for GC and HPLC sample introduction. Choose this ND9 short thread cap when a blue PP housing with hole and aluminium flat-seal construction is specified for your vial system.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about 9mm seal: PP short thread cap, blue, hole, Aluminum seal, 0,06 mm, 10 x 100 pc
What is this article?
9mm seal: PP short thread cap, blue, hole, Aluminum seal, 0,06 mm, 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.
