Description
Crimping pliers for 20 mm crimp caps are a manual crimping tool intended for 20 mm aluminium closures used in laboratory sealing work. Hardened closing jaws made from a special alloy provide chemical resistance for routine bench use. Crimping pressure and height are individually adjustable, so the seal can be matched to the closure and application. Handling is simple and comfortable for repeated sealing of vials and similar containers. Supplied as one piece from manufacturer Altmann Analytik, this tool is positioned as an alternative to VWR 548-0073, Labhut Cronus VTC-20 and Agilent 5040-4669. It supports secure aluminium crimp seals in sample preparation, chromatography and general analytical workflows where consistent manual crimping of 20 mm caps is required. The combination of adjustable settings, chemically resistant jaws and straightforward operation makes it a practical choice for laboratories standardising on 20 mm aluminium crimp closures.
This article is part of Crimpers & decappers, in Vials, caps & septa.

Questions about Manual Crimper for 20 mm caps
What is this article?
Manual Crimper for 20 mm caps is the article on this page. Luminix Health distributes Altmann Analytik for laboratory use. It sits in Crimpers & decappers, inside Vials, caps & septa, in Chromatography equipment.
A crimper closes a crimp cap onto a vial neck. A decapper takes it off. The jaw size, 11 mm or 20 mm, has to match the cap. A crimp that is too tight cracks the neck. One that is too loose leaks in the tray. Electronic and manual tools differ in how repeatable the squeeze is.
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.
