Description
Rotilabo® rolled edge vials ND20 are flat-bottom sample vials designed for liquid chromatography workflows, including HPLC sample handling and storage. Each vial offers a 10 ml working volume with outer dimensions of Ø 20 × H 54,5 mm and a rolled ND20 neck profile that accepts matching crimp or tear-off closures. The flat base supports stable standing on benches, racks and autosampler trays, helping laboratories organise standards, intermediates and prepared samples with consistent geometry. Supplied in packs of 100 pieces and weighing 0,500 kg per unit pack, these vials suit routine preparation of mobile-phase aliquots, calibration solutions and injection-ready fractions. The Rotilabo® line from manufacturer ROTH SELECTION is positioned for everyday chromatography consumable use where reliable neck finish and clear dimensional definition matter. Compatible ND20 aluminium or composite caps with suitable septa complete the closure system for short-term holding or transfer between preparation and analysis. Use these rolled-edge vials wherever standardised ND20 glassware is specified for LC, HPLC or related liquid-handling steps in analytical and quality-control laboratories.

Questions about Rotilabo® rolled edge vials ND20, flat bottom, 10 ml, Ø 20 x H 54,5 mm
What is this article?
Rotilabo® rolled edge vials ND20, flat bottom, 10 ml, Ø 20 x H 54,5 mm 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.
