Description
Caps for storage vials, ND15 are polypropylene screw closures equipped with a closed sealing pad of Butyl/PTFE for reliable sealing of compatible laboratory storage vials. The ND15 geometry and closed-cap format help maintain sample integrity during storage, handling and intermediate holding before analysis or further processing. A PP shell combined with a Butyl/PTFE liner offers a practical sealing option widely used in analytical and research laboratories. Packs of 100 pc(s) from manufacturer ROTH SELECTION supply a convenient quantity for high-throughput benches, QC laboratories and facilities that standardise on ND15 storage vials. These caps align with Rotilabo®-style autosampler and sample-bottle workflows and support consistent manual or assisted capping. Uniform construction aids reproducible sealing performance across batches of vials. Pack weight is 0,110 kg. Choose this closed PP cap with Butyl/PTFE sealing pad when your protocols call for that liner combination on ND15 storage vials used for routine sample retention and laboratory logistics.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Caps for storage vials, ND15, PP, sealing pad, closed, Butyl/PTFE, 100 unit(s)
What is this article?
Caps for storage vials, ND15, PP, sealing pad, closed, Butyl/PTFE, 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.
