Description
13 mm polypropylene screw caps in black, supplied with a centre hole and a natural rubber red-orange / TEF transparent septum of 1,3 mm thickness, are intended for sealing compatible chromatography or sample vials in routine laboratory use. The open-hole design allows needle access through the septum for injection or withdrawal while the screw thread provides a secure closure on matching 13 mm neck finishes. The laminated NR/TEF septum combines an elastomeric sealing layer with a chemically resistant fluoropolymer contact face toward the sample. These caps from manufacturer Altmann Analytik are packed in units of 1000 pc(s) for high-throughput or stock replenishment needs. Black PP construction offers a standard, easily identified closure for analytical workflows. The 1,3 mm septum thickness supports reliable resealing under typical autosampler conditions. Suitable as a replacement or bulk accessory for laboratories standardising on 13 mm screw-thread vials with pierced-cap sampling.

Questions about 13 mm PP screw cap, black, with hole, NK red-orange/TEF transparent, 1.3 mm
What is this article?
13 mm PP screw cap, black, with hole, NK red-orange/TEF transparent, 1.3 mm 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.
