Description
Pre-sealed N24 screw-neck bottle is a ready-to-use 60 mL amber glass container supplied with a factory-fitted bonded closure for sample storage and transport. The bottle has an outer diameter of 27,5 mm and an outer height of 140 mm, a flat bottom and brown glass that helps shield light-sensitive contents. It is pre-assembled with a white N24 PP screw cap with centre hole and a bonded silicone white/PTFE beige septum, 3,2 mm thick at 45° Shore A hardness. Offered in packs of 100 pieces from manufacturer Macherey-Nagel, the combination cuts assembly time and supports consistent seal quality across a batch. The bonded septum design aids reliable resealing after needle access in sampling workflows. Suitable for laboratory storage, sample preparation and chromatography-related work that needs amber glass with an N24 thread, this pre-sealed format streamlines handling of larger sample volumes on the bench and in transit.

Questions about Pre-sealed: 702131 + 702058
What is this article?
Pre-sealed: 702131 + 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.
