Description
ND15 PP screw caps in black, closed design with a 1,3 mm septum (silicone white / PTFE red) are laboratory closures for ND15 vial necks. The polypropylene screw cap provides a robust threaded seal, while the white silicone face bonded to red PTFE offers a chemically resistant septum surface for sampling and injection workflows. Closed-top construction suits applications where a solid cap with integrated septum is required rather than an open-hole design. Packaged as 10 × 100 pieces per pack (1000 pieces), the unit supports high-volume chromatography and sample-preparation environments. Septum thickness of 1,3 mm balances ease of penetration with resealing performance in routine use. These ND15 screw caps from manufacturer Altmann Analytik are positioned as an alternative to corresponding closures from Agilent, Waters, Chromacol, National Scientific, Wheaton, Finneran and SUN/SRI International ranges. Black PP bodies give a clear visual identity on the bench and in autosampler trays. Suitable for laboratories standardising on ND15 screw-thread vial systems with Si/PTFE septa.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about ND15 PP screw cap, black, closed,1,3mm, 10 x 100 pc
What is this article?
ND15 PP screw cap, black, closed,1,3mm, 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.
