Description
The Spotting Guide for TLC plates is a practical accessory for precise sample application on large-format thin-layer chromatography plates of 20 x 20 cm. It helps operators place samples reproducibly at the starting line prior to development, supporting consistent TLC results in analytical and preparative workflows. Supplied as a single piece weighing 0,200 kg, the guide is dimensioned for standard 20 x 20 cm plates widely used in laboratories that require greater separation distance or higher sample capacity. The biostep (DESAGA) design from manufacturer Bionis belongs to the established DESAGA TLC accessory family. It is suited to routine spotting operations that precede chamber development, visualisation and documentation. With a unit quantity of one piece, the guide is easy to keep on hand for dedicated 20 x 20 cm plate work. Use it in research, quality control or teaching environments where controlled sample placement on full-size TLC plates is essential.
This article is part of TLC & HPTLC plates, in TLC.

Questions about Spotting Guide for TLC plates, biostep (DESAGA), 20 x 20 cm
What is this article?
Spotting Guide for TLC plates, biostep (DESAGA), 20 x 20 cm is the article on this page. Luminix Health distributes Bionis for laboratory use. It sits in TLC & HPTLC plates, inside TLC, in Chromatography equipment.
A TLC plate is a backing, glass, aluminium or plastic, coated with silica or alumina of a stated thickness. HPTLC uses a finer particle and a thinner layer. Indicator plates fluoresce so a dark spot shows under UV. Plate size and layer thickness are the specification.
Thin-layer chromatography runs a liquid up a plate coated with a sorbent. The compounds move different distances and are seen as spots. HPTLC is the same method with a finer layer. The plate, the solvent mixture and the chamber saturation decide the result. It is the quick look before, or beside, a column method. The substances are on PubChem, named by IUPAC.
