Description
Snap ring caps in hard version, made from polyethylene (PE) for ND11 neck finish, provide dependable closures for autosampler vials and sample bottles in analytical laboratories. They are fitted with a Natural rubber/TEF septum of 1,0 mm thickness at 65°, offering a controlled sealing surface for sample containment during storage, transport and instrument injection sequences. The hard PE construction aids firm, repeatable snap-on seating on matching ND11 vials and supports everyday use in chromatography sample preparation and related labware applications. Each pack contains 100 pc(s) and weighs 0,040 kg, convenient for shared stocks and continuous autosampler operation. Natural rubber/TEF septa are selected when a resilient elastomer with a fluoropolymer contact layer is preferred for the intended solvent and matrix range. These snap ring caps from manufacturer ROTH SELECTION align with common ND11 snap-ring vial formats used in laboratory glass, vessels and consumables. They enable tool-free capping for workflows that specify hard PE ND11 closures with Natural rubber/TEF septa and help maintain sample integrity through defined septum thickness and hardness characteristics.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Snap ring caps, hard version, PE, ND11, Septum Natural rubber/TEF, 1.0 mm 65°
What is this article?
Snap ring caps, hard version, PE, ND11, Septum Natural rubber/TEF, 1.0 mm 65° 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.
