Description
Rotilabo® rolled edge vials with long neck are ND20 flat-bottom vials for liquid chromatography sample handling, including HPLC applications. Each vial provides a 20 ml capacity with outer dimensions of Ø 22,5 × H 75,5 mm, offering a taller long-neck format and a flat standing base for secure placement. The ND20 rolled-edge neck finish is aligned with standard ND20 closure approaches used in chromatographic sample preparation and holding of larger liquid aliquots. Delivered as 100 pc(s) per pack, the vials form part of the Rotilabo® assortment from manufacturer ROTH SELECTION and support everyday LC, HPLC and LC-MS laboratory workflows. The combination of long neck, flat bottom and 20 ml volume suits preparation, dilution and transfer steps that need more headspace or working volume than smaller vials. Explicit dimensional data help laboratories select the correct geometry for method and instrument fit. With a pack weight of 1,675 kg for 100 pc(s), the unit quantity is practical for continuous use. These rolled edge vials meet standard HPLC sample-container requirements where ND20 compatibility, 20 ml capacity and Ø 22,5 × H 75,5 mm long-neck geometry are specified.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Rotilabo® rolled edge vials, long neck, ND20, flat bottom, 20ml, Ø 22.5xH75.5mm
What is this article?
Rotilabo® rolled edge vials, long neck, ND20, flat bottom, 20ml, Ø 22.5xH75.5mm 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.
