The Chromatogram Immersion Device 3 is used for automated dipping. TLC/HPTLC plates are immersed with uniform vertical speed into derivatization reagents or solutions for plate impregnation.
For proper reagent transfer, the chromatogram must be immersed and withdrawn at a controlled uniform speed. By maintaining a well defined vertical speed and immersion time, derivatization conditions can be standardized and «tide marks», which can interfere with densitometric evaluation, are avoided.
