1. A sampling and analysis device comprising:
a control unit for controlling the sampling and analysis device;
a tape wound on a tape reel carrying the tape, said tape comprising a base material with a series of reagent pads, the reagent pads arranged to provide a detectable response in the presence of at least one substance in the sample;
a tape mover, arranged to move and unwind the tape;
a dosing device arranged to provide a part of the sample onto one of the reagent pads; and
an optical sensor device arranged to detect optical radiation from said reagent pad supplied with said part of the sample, and to analyze the detected optical radiation to provide an indication of a presence or concentration of said at least one substance,
wherein the dosing device comprises:
a displaceable nozzle having an opening and a supply line for supplying a portion of the milk sample to the nozzle, the nozzle being adjacent to and below the reagent pads for supplying the part of the sample upwardly to the reagent pad, wherein the dosing device further comprises a nozzle mover arranged to move the displaceable nozzle towards and away from the tape, and an overflow device comprising a wall at least partly surrounding the nozzle, an overflow space being provided between the wall and the nozzle, and a discharge connected or connectable to the overflow space.
