Description
11 mm magnetic crimp cap, silver lacquered, with hole and PTFE red/silicone white septum is a sealing closure for ND11 roll-rim vials used in chromatographic sample handling. The silver-lacquered magnetic shell supports automated crimping and magnetic transport on compatible autosamplers, while the centre hole allows syringe or needle penetration through the septum. The septum stack is specified as PTFE red facing the sample side with silicone white as the backing layer, combining chemical contact resistance of PTFE with the elasticity of silicone for a dependable seal. Packaged as 1000 pc(s), the caps suit high-volume laboratory preparation lines. Offered by manufacturer Altmann Analytik, this 11 mm magnetic crimp cap integrates into standard ND11 workflows for HPLC and GC sample introduction, method development, and routine analysis where magnetic handling and a defined PTFE/silicone septum orientation are required. Use with matching ND11 vials to maintain consistent headspace sealing and instrument compatibility across analytical batches.

Questions about 11 mm magnetic flare cap, silver painted, w/ hole, PTFE red/silicone white/PTFE
What is this article?
11 mm magnetic flare cap, silver painted, w/ hole, PTFE red/silicone white/PTFE is the article on this page. Luminix Health distributes Altmann Analytik 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.
