Description
Pre-sealed 1,5 mL N 11 crimp-neck vials combine clear glass roll-neck bottles with factory-crimped aluminium closures for ready-to-use analytical sampling. Each vial (type 70201CG) has an outer diameter of 11,6 mm and an outer height of 32 mm, with a flat bottom and narrow opening. The matched N 11 aluminium crimp cap (type 70231) is silver with a centre hole and a natural rubber/butyl red-orange/TEF colourless septum, hardness 45° Shore A and septum thickness 1,3 mm. Units are supplied already crimped, reducing manual assembly steps before filling or injection. Packs of 100 pieces are available from manufacturer Macherey-Nagel for chromatography and laboratory workflows that specify N 11 pre-sealed clear vials. The narrow-mouth geometry and laminated septum support needle access while the aluminium crimp secures the seal on the roll neck. Clear glass allows visual checks of fill level and sample appearance during preparation and storage on the bench or in autosampler trays.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Pre-sealed: 70201CG + 70231
What is this article?
Pre-sealed: 70201CG + 70231 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.
