Description
Rotilabo® headspace vials ND20 provide a larger 20 ml capacity for chromatography sample preparation where greater headspace or liquid volume is required. The vials feature a rounded bottom and measure Ø 23 × H 75,5 mm, matching common ND20 autosampler and incubator formats used in liquid chromatography and HPLC environments. The taller profile accommodates extended sample equilibration while the rounded base supports even thermal contact. Packs contain 100 pc(s) and come from manufacturer ROTH SELECTION as part of the Rotilabo® laboratory consumables range. At a pack weight of 1,680 kg, the quantity suits medium-throughput analytical series as well as method validation work. ND20 neck compatibility allows laboratories to retain existing crimp or screw closure systems already validated for headspace-style sampling. Clear dimensional definition (Ø 23 mm diameter, 75,5 mm height) simplifies tray layout and instrument method setup. These vials are positioned for routine chromatography applications that call for a robust 20 ml ND20 vessel with a rounded bottom.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Rotilabo® headspace vials ND20, round. bottom, 20ml, Ø 23xH 75.5mm, 100 unit(s)
What is this article?
Rotilabo® headspace vials ND20, round. bottom, 20ml, Ø 23xH 75.5mm, 100 unit(s) 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.
