Description
Magnetic crimp caps with borehole in aluminium for ND20 neck finishes provide a practical sealing option for laboratory autosampler and sample-vial workflows. Each cap is supplied with a silicone/PTFE septum of 3,0 mm thickness cut at 45°, and features a central hole diameter of 8 mm to support needle access during sampling or injection steps. The magnetic aluminium construction suits magnetic transport and handling systems commonly used with ND20 crimp-neck vials in analytical laboratories. These ROTILABO® ND20 magnetic crimp caps with borehole are intended for routine sample containment, chromatography sample preparation, and related laboratory glassware applications where a reliable crimp seal and defined borehole geometry are required. Offered from manufacturer ROTH SELECTION as a pack of 100 pieces, the set supports high-throughput vial preparation and consistent sealing practice across multiple runs. Clear dimensional definition of the septum and hole helps match the caps to compatible ND20 vials and autosampler configurations without guesswork. Suitable for general laboratory consumable stock covering autosampler vials and sample bottles, they integrate straightforwardly into standard crimp-capping procedures used in chemical, pharmaceutical, and environmental analysis environments.

Questions about Crimp caps ROTILABO® ND20 magnetic with borehole
What is this article?
Crimp caps ROTILABO® ND20 magnetic with borehole is the article on this page. Luminix Health distributes Carl Roth 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.
