Material: borosilicate glass 3.3. 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.

Not suitable for use with reagents. Simultan TLC Developing Chamber biostep ® (DESAGA) TLC separation chamber with smooth edges and flat base for the simultaneous separation of 5 TLC/HPTLC plates. This chamber is often used for washing TLC plates before use and then for protected storage of the plates. This method is used in particular for quantitative trace analysis. The vertical grooves in the cross walls hold up to five 200 x 200 mm plates. The chamber has a flat bottom. The lid can be used during pre-washing.
