Description
Flange caps with bore hole, Al, ND11 are aluminium closures for ND11 autosampler and chromatography vials that require a pre-bored flange seal. These caps carry a silicone/PTFE Ultra Clean septum measuring 1,3 mm at 45°, chosen for clean sample contact and consistent piercing behaviour in HPLC and related liquid-chromatography workflows. The aluminium flange design locks securely onto matching ND11 welt-rim vials, supporting dependable sealing during storage and automated injection. Each pack contains 100 pc(s) and weighs 0,035 kg, making the format convenient for instrument stock and method-support benches. Available from manufacturer ROTH SELECTION, the caps address laboratories that specify ND11 aluminium flange caps with an Ultra Clean silicone/PTFE septum. Use them wherever a bored Al ND11 flange cap with a 1,3 mm 45° Silic./PTFE Ultra Clean septum is required for autosampler vial systems.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Flange caps with bore hole, Al, ND11, Septum Silic./PTFE Ultra Cl., 1.3 mm 45°
What is this article?
Flange caps with bore hole, Al, ND11, Septum Silic./PTFE Ultra Cl., 1.3 mm 45° is the article on this page. Luminix Health distributes Carl Roth 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.
