Abstract:
The invention relates to a test set for a photometric measuring device, comprising a mixing container (1) which receives a first fluid (5) in its interior (4) and a closing element which is removable from its filling opening (3), and a dosing container (8) which contains a second fluid (13) in a sealed hollow chamber (9), with the hollow chamber (9) being sealed on one side by a displaceable sealing plunger (11) and on the opposite side by a movable plug (10), and with the dosing container (8) being insertable in a sealing manner into the filling opening (3) of the mixing container (1). For the purpose of simplifying the input of the sample, the dosing container (8) comprises an integrated sample-taking device (21) which after the insertion of the dosing container (8) in the filling opening (3) of the mixing container (1) is in contact with the first fluid (5) present in the mixing container (1).
Abstract:
The invention relates to a test set (1) for a photometric measuring device, comprising a mixing container (2) which has a filling opening (3) and comprising a metering container (8) which can be sealingly inserted into the filling opening (3) of the mixing container (2) and which contains a liquid reagent (13) in a closed cavity (9). The cavity (9) has a closure plunger (11), which can be moved axially in the cavity (9), at a first end of the metering container (8), said closure plunger generating a specifiable filling pressure in the reagent (13), and the metering container (8) has a closure membrane (10) at a second metering container and which can be inserted into the mixing container (2). According to the invention, the closure membrane (10) is equipped with a predetermined breaking point (20) which breaks open when the filling pressure is exceeded in a defined manner as a result of an axial movement of the closure plunger (11), said predetermined breaking point (20) of the closure membrane (10) being formed as a linearly extending material taper of the closure membrane (10), wherein the taper is arranged eccentrically in the region of an opening (24) in the base (23) of the substantially cylindrical metering container (8).
Abstract:
The invention relates to a mixing container (1) for a photometric measuring device, comprising a closing element (2) that can be removed from a filling hole (3) and a first liquid (5) which is located in the interior (4) of the mixing container (1), with the mixing container (1) comprising a dosing element (8) which can be placed on the filling hole (3) of the mixing container (1) after removing the closing element (2) and adding a sample liquid, and with the dosing element (8) containing a second liquid (13) in a closed hollow space (9). In accordance with the invention, the hollow space (9) in the dosing element (8) is closed by a movable plug (10) which is discharged into the interior of the mixing container (1) along with the second liquid (13) once the second liquid (13) has been subjected to pressurization.
