Description
Pre-sealed combination 702132 + 702058 comprises clear 30 mL N 24 screw-thread bottles already closed with bonded polypropylene screw caps for ready-to-use laboratory sample handling. Each bottle has an outer diameter of 27,5 mm, an outer height of 72,5 mm and a flat bottom, giving a stable footprint on the bench and in racks. The matching N 24 PP screw cap is white, open-top and bonded, with a white silicone and beige PTFE septum at 45° Shore A hardness and 3,2 mm septum thickness for dependable sealing and needle access. Supplied as a pack of 100 pre-assembled units from manufacturer Macherey-Nagel, this set reduces manual capping steps before storage, transport or chromatographic sample work. Clear glass allows visual inspection of contents, while the PTFE-faced septum supports chemical resistance toward many common solvents. Ideal as labware for workflows that specify N 24 thread geometry, defined bottle dimensions and a bonded silicone/PTFE closure without separate assembly of vials and caps.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Pre-sealed: 702132 + 702058
What is this article?
Pre-sealed: 702132 + 702058 is the article on this page. Luminix Health distributes Macherey-Nagel 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.
