Description
neochrom® aluminium crimp caps ND11 with hole and PTFE red/silicone/PTFE red septum are chromatography closures designed for reliable vial sealing in analytical workflows. These colourless lacquered aluminium crimp seals feature a central opening of 5,5 mm and are supplied as a pack of 100 pieces for routine laboratory use. The multilayer PTFE red/silicone/PTFE red septum supports controlled needle penetration and is suited to single-injection applications; silicone/PTFE-type septa of this family are specified for a working range from −60 °C to +200 °C with a typical septum thickness of 1,3 mm. Aluminium ND11 crimp caps of this design are established standard closures for gas chromatography and HPLC sample preparation, where a secure mechanical seal and defined pierceable barrier are required. Offered from manufacturer neolab - Labor under the neochrom® line, the caps integrate cleanly with matching ND11 vials and common crimping tools. They are intended as consumable accessories for chromatography sample handling rather than as general-purpose laboratory stoppers, supporting consistent sealing performance across analytical sequences.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about neochrom® Alu-Bördelkappen ND11 mit Loch, Septum PTFE rot/Silikon/PTFE rot, 100
What is this article?
neochrom® Alu-Bördelkappen ND11 mit Loch, Septum PTFE rot/Silikon/PTFE rot, 100 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.
