Description
Crimp cap, 20 mm aluminium, red lacquered, centre tear-off, is a laboratory sealing cap for 20 mm neck vials that combines aluminium strength with a clearly visible red lacquer finish. The centre tear-off design allows controlled opening after crimping, supporting workflows where rapid access to the vial contents is required after sealing. Each pack contains 1000 pieces, making the product suitable for busy analytical and quality-control laboratories with steady consumable demand. Red lacquer aids quick visual differentiation on the bench or in storage, reducing mix-ups between closure types. These 20 mm aluminium crimp caps are used to secure vials in chromatography sample preparation and related laboratory sealing applications. From manufacturer Altmann Analytik, the caps fit standard 20 mm crimp systems when applied with an appropriate crimping tool. The combination of aluminium body, red lacquer coating, and centre tear-off feature provides a practical closure option for laboratories that need identifiable, easy-open 20 mm seals in bulk pack size.

Questions about 20mm Aluminum flanged cap, red lacquered, Mittelabriss, 1000/PAK
What is this article?
20mm Aluminum flanged cap, red lacquered, Mittelabriss, 1000/PAK 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.
