Description
Rotilabo® rolled edge vials ND20 are intermediate-volume glass vials built for chromatography sample handling with a defined rolled-edge ND20 finish. Each vial holds 10 ml, has a rounded bottom and external dimensions of Ø 22,5 × H 46 mm, offering a balanced height-to-diameter ratio for trays and heating stations. The rolled edge supports secure seating of compatible ND20 closures used in liquid chromatography and HPLC workflows. Available in packs of 100 pc(s) from manufacturer ROTH SELECTION, the format suits laboratories that standardise on ND20 consumables across multiple instruments. Pack weight is 1,107 kg, which is convenient for stock rotation and bench-side supply. The 46 mm height keeps the vial compact relative to larger headspace formats while still providing adequate working volume for sample dilution, extraction aliquots or intermediate storage prior to injection. Rounded-bottom geometry promotes uniform contact with heated surfaces. These Rotilabo® rolled edge ND20 vials integrate cleanly into established chromatography sample-preparation lines that specify 10 ml vessels.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Rotilabo® rolled edge vials ND20, rounded bottom, 10 ml, Ø 22.5 x H 46 mm
What is this article?
Rotilabo® rolled edge vials ND20, rounded bottom, 10 ml, Ø 22.5 x H 46 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.
