The invention relates to a test set (1) for a photometric measuring device, comprising a mixing container (2) having a filling opening (3) and a metering container (8) which can be inserted sealingly into the filling opening (3) of the mixing container (2) a sealed cavity (9) containing a liquid reagent (13), wherein the cavity (9) at a first end of the dosing (8) in the cavity (9) axially displaceable sealing piston (11), which has a predetermined filling pressure in the reagent (13) generated. To simplify the production and handling of the dosing (8) at its second, in the mixing container (2) usable end of a closure membrane (10) which is equipped with a predetermined breaking point (20), which at a defined exceeding of the filling pressure - triggered by an axial displacement of the closure piston (11) - breaks. |
