Material: PTFE. In thin-layer chromatography, the separation of the components of a mixture is the most delicate step, as it is subject to different and variable parameters. Some are perfectly controlled (chemical nature of the stationary and mobile phase), others are more random (degree of humidity, ambient temperature, pre-saturation). All require precise and rigorous protocols to achieve correct, repeatable and reproducible separations. The quality of the migration separation chamber and the choice of its size and shape are very important.

Horizontal Developing Chamber for TLC biostep ® (DESAGA) For analysing small-format plates. The H separating chamber optimally utilises the advantages of the high-performance TLC coating: small grain size 5 µm better packing more theoretical plates faster migration of the HPTLC optimum separations even with the shortest runs Anywhere, especially where time is limited and clear results must be achieved, is the ideal place to use the H separation chamber: in the laboratory and in the pharmacy. The chambers are made of solvent-resistant PTFE, precisely milled and sealed with a 4 mm thick glass cover disc. Easy-to-clean glass frit rods guide the superplasticiser to the layer. Delivery incl. frit rods and cover plate.
