ABSTRACT:
A detecting device in the form of a testing tube or dosimeter having a carrier indicating a color reaction requires a reagent liquid for carrying out a measurement. The reagent liquid is contained in a separate reagent supply vessel and the carrier is impregnated with a color indicator. For carrying out a measurement, the reagent supply from the supply vessel must be brought into contact with the porous carrier. A uniform wetting of the surface of the carrier subjected to the reagent solution is achieved after the reagent solution is emptied from the supply vessel. This is achieved by providing a reagent collection chamber between the carrier and the reagent supply vessel into which the reagent solution pours when the supply vessel is opened and wherein the reagent solution is accommodated and into which the carrier extends so that its end face is subjected to the reagent solution so that this end face can be wetted at the same time.
