Improvement to the development stage of thin film chromatography, development device for implementing such improvement and installation comprising this device. The thin layer chromatography development process entails contact being made under relatively even pressure between the chromatography developing plate and a suitable material impregnated with a suitable substance or developing reagent. The developing device for thin layer chromatography includes: porous material (20, 20', 72), which resists the ordinary chromatography development reagents and is absorbent enough to impregnate completely a chromatography plate without immersing it at the time of contact under pressure and to reabsorb the surplus reagent when the porous material is withdrawn from the chromatography plate; and a handling support (10, 11, 10', 11', 70) which is inert in relation to the development reagents and rigid enough to allow for suitable pressure to be placed on a thin layer chromatography plate and on which the porous material is mounted or fixed.
