Description
Rotilabo® rolled edge vials ND20 are flat-bottom vials sized for larger liquid chromatography sample volumes, including HPLC-related handling. Each vial offers a 50 ml capacity with outer dimensions of Ø 31 × H 101 mm, providing a spacious format with a stable flat base for bench and rack use. The ND20 rolled-edge neck finish supports standard ND20 sealing practices common in chromatographic sample preparation and intermediate holding of bulkier aliquots. Packed as 100 pc(s), these vials belong to the Rotilabo® line from manufacturer ROTH SELECTION and fit routine LC, HPLC and LC-MS laboratory environments where higher working volume is needed. The flat bottom promotes secure standing during filling, mixing and transfer operations. Clear volume and dimensional specifications help match the vial to method scale and storage or handling constraints. At a pack weight of 3,120 kg for 100 pc(s), the unit quantity supports laboratories with steady demand for larger ND20 vials. These rolled edge vials address HPLC sample-container needs when ND20 compatibility, a 50 ml working volume and Ø 31 × H 101 mm geometry are required.

Questions about Rotilabo® rolled edge vials ND20, flat bottom, 50 ml, Ø 31 x H 101 mm
What is this article?
Rotilabo® rolled edge vials ND20, flat bottom, 50 ml, Ø 31 x H 101 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.
