Description
Rotilabo® screw-neck ND18 vials are clear-glass sample containers designed for liquid chromatography workflows, including HPLC sample handling and storage. Each vial offers a 20 ml working volume with external dimensions of Ø 23 × H 75,5 mm and an ND18 screw neck for secure closure compatibility in routine laboratory use. The transparent glass body supports visual inspection of sample level and clarity during preparation, transfer, and short-term holding steps common in LC and LC-MS environments. Supplied as a practical multipack of 100 pieces, the format suits high-throughput chromatography benches where consistent vial geometry and neck finish help standardise autosampler and manual handling practices. These Rotilabo® vials from manufacturer ROTH SELECTION fit established ND18 screw-thread accessories and are intended for general laboratory sample containment rather than specialised reaction chemistry. Clear glass construction aids identification of contents and residual volume at a glance, while the defined height and diameter support organised racking and transport within chromatography suites. The pack weight is approximately 1,680 kg, reflecting the robust glass build of the full 100-piece unit suitable for shared lab stocks and method-development work.

Questions about Rotilabo®-screw-neck ND18, clear glass, 20 ml, Ø 23 x H 75.5 mm, 100 unit(s)
What is this article?
Rotilabo®-screw-neck ND18, clear glass, 20 ml, Ø 23 x H 75.5 mm, 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.
