Description
Rotilabo® screw neck ND8 vials are clear glass chromatography vials with a conical base and a nominal volume of 1,1 ml for liquid chromatography sample handling. The ND8 screw-neck design is intended for use with matching screw closures in HPLC and related LC workflows, supporting secure sealing during autosampler runs and short-term sample holding. Clear glass enables easy visual checks of fill level and sample appearance before injection. The conical base helps concentrate residual liquid when working with limited sample volumes, which is useful in routine HPLC and LC-MS sample preparation. Packaged as 100 pc(s) with a pack weight of 0,300 kg, these vials suit everyday analytical laboratory consumption. Offered under the ROTH SELECTION range, they align with standard ND8 vial formats used in liquid chromatography (LC, HPLC, LC-MS). Laboratories can deploy them for sample storage, transfer, and instrument loading where clear glass ND8 screw-neck vials with a conical base are specified. The combination of clear glass, conical geometry, and 1,1 ml capacity supports consistent handling in chromatography benches and autosampler trays.

Questions about Rotilabo®-screw neck ND8 vials, clear glass, conical base, 1.1 ml, 100 unit(s)
What is this article?
Rotilabo®-screw neck ND8 vials, clear glass, conical base, 1.1 ml, 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.
