Description
neochrom® Septum ND20 silicone blue transparent/PTFE transparent is a septum for ND20 crimp closures, combining blue transparent silicone with a transparent PTFE face. The silicone/PTFE construction is temperature resistant from −60 °C to 200 °C and is formulated for easy needle penetration, which supports smooth autosampler operation and reduced coring risk during repeated injections. It is intended for critical analyses where septum inertness and clean penetration behaviour matter. Each pack contains 1000 pieces, enabling efficient stocking for high-sample-throughput chromatography laboratories. These ND20 septa from manufacturer neolab - Labor are matched to standard crimp-cap vial systems and suit workflows that specify silicone/PTFE laminates for demanding analytical conditions. The blue transparent silicone body with transparent PTFE layer offers clear visual identification on the bench while maintaining the sealing and chemical-contact properties expected of PTFE-faced septa. Choose this format when ND20 crimp septa with wide temperature range and easy penetration for critical analyses are required.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about neochrom® Septum ND20, Silikon blau transparent /PTFE transparent, 1000 St./Pack
What is this article?
neochrom® Septum ND20, Silikon blau transparent /PTFE transparent, 1000 St./Pack is the article on this page. Luminix Health distributes neolab 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.
