Description
Opening pliers and crimping pliers for 28 mm crimp caps provide a practical hand tool for sealing and opening laboratory vials with matching crimp closures. The hand crimping pliers are simple and comfortable to operate, supporting controlled, repeatable work at the bench. Crimping pressure can be limited and fine-tuned with an adjusting screw integrated in the handle, so the force applied to the cap can be adapted to the application. A chemically resistant surface coating protects the tool during routine laboratory handling and helps maintain reliable performance when reagents and solvents are nearby. Supplied as a single piece from manufacturer Altmann Analytik, this dual-function pliers set is tailored to everyday lab workflows involving 28 mm crimp caps. It suits sample preparation, chromatography sample handling, and general analytical work where secure, consistent crimp seals are required. Compact and easy to grip, the tool supports efficient sealing and opening without complex setup, making it a dependable accessory for vial-based laboratory processes.

Questions about 28 mm Decapper
What is this article?
28 mm Decapper 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.
