Description
Rotilabo® headspace vials ND20 are compact glass sample vials designed for chromatography workflows that require a reliable ND20 neck format. Each vial offers a 5 ml working volume, a rounded bottom and external dimensions of Ø 22 × H 38,2 mm, giving a stable footprint on autosampler trays and in heating blocks. The ND20 geometry supports standard crimp or screw closures commonly used in headspace and related HPLC sample preparation. Supplied in packs of 100 pc(s) from manufacturer ROTH SELECTION, the set is intended for routine liquid chromatography and HPLC laboratories that process multiple samples per run. The rounded base aids uniform heating and reduces dead volume at the bottom of the vessel, while the short overall height of 38,2 mm keeps the assembly compact in crowded sample racks. With a pack weight of 0,925 kg, the unit quantity is practical for both method development and day-to-day analytical series. These Rotilabo® ND20 headspace vials fit established laboratory consumable lines for chromatography sample handling without unnecessary complexity.

Questions about Rotilabo® headspace vials ND20, rounded bottom, 5ml, Ø 22xH 38.2mm, 100 unit(s)
What is this article?
Rotilabo® headspace vials ND20, rounded bottom, 5ml, Ø 22xH 38.2mm, 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.
