Description
Screw caps with bore hole in PP for ND9 vials are laboratory closures equipped with a Silic./PTFE UltraCl. septum rated 1,0 mm and 55°. The polypropylene screw shell includes a centre bore so autosampler needles can pass through the silicone/PTFE UltraCl. septum while the cap remains fitted to the vial. These components sit within the autosampler vial and sample-bottle consumables group used for sealed sample storage and instrumental injection. Each pack contains 100 pc(s) and weighs 0,125 kg, aligning with standard ND9 short-thread vial systems. This configuration from manufacturer ROTH SELECTION pairs a PP bore-hole cap with a Silic./PTFE UltraCl. septum for routine chromatography sample handling. The 1,0 mm thickness and 55° specification identify the sealing disc supplied on this article. Laboratories running ND9 autosampler vials can deploy the closures wherever a silicone/PTFE UltraCl. septum and screw closure are required together. Cap material, ND9 neck size, septum type and pack quantity fully describe the product for laboratory glass and vial accessory inventories.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Screw caps with bore hole, PP, ND9, Septum Silic./PTFE UltraCl., 1.0 mm 55°
What is this article?
Screw caps with bore hole, PP, ND9, Septum Silic./PTFE UltraCl., 1.0 mm 55° 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.
