Description
Spotting guide for TLC plates, biostep (DESAGA), 5 x 5 cm, is a precision accessory for sample application on thin-layer chromatography plates in the compact 5 x 5 cm format. Spotting guides help operators place starting spots at consistent positions along the origin line, which supports reproducible Rf evaluation and orderly multi-sample runs on small TLC plates. This guide is specified for biostep (DESAGA) TLC workflows and is suited to laboratories that routinely develop 5 x 5 cm plates in analytical screening, teaching practicals, or method scouting. Offered as one piece from manufacturer Bionis, it belongs to the biostep (DESAGA) thin-layer chromatography accessory range. The unit weight is 0,024 kg, so it is light to position on the plate, easy to clean between uses, and simple to store with other TLC tools. When used during manual sample spotting, the guide assists alignment before chamber development and subsequent visualisation. It is a practical addition for labs standardising plate loading on small-format TLC systems without altering established DESAGA-oriented working practices.
This article belongs on TLC & HPTLC plates, in TLC.

Questions about Spotting Guide for TLC plates, biostep (DESAGA), 5 x 5 cm
What is this article?
Spotting Guide for TLC plates, biostep (DESAGA), 5 x 5 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.
