Description
Silicone septa soft, N 12 are soft silicone sealing discs sized for N 12 closures used with laboratory vials and related sample containers. Each septum has an outer diameter of 12 mm and a thickness of 3 mm, giving a compliant soft seal for routine analytical and sample-handling setups that specify the N 12 format. The pack contains 50 pieces, convenient for stocking chromatography, sample preparation, or general vial workflows that consume septa regularly. Soft silicone construction supports reliable resealing performance typical of this consumable class, while the defined 12 mm diameter and 3 mm thickness allow straightforward matching to compatible caps and necks. These septa from manufacturer Macherey-Nagel are supplied non-sterile as standard laboratory sealing components. Compact packaging keeps the 50-piece unit easy to store beside autosampler vials and manual sample bottles. Choose soft N 12 silicone septa when a precise 12 mm × 3 mm soft seal is required in packs sized for ongoing laboratory demand.

Questions about Silicon septa soft, N 12
What is this article?
Silicon septa soft, N 12 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.
