The present disclosure relates to a method for metering a liquid into a wet chemistry analytical device wherein a specified volume of individual liquids is placed in a metering unit consisting of a metering container and at least one dose measuring device. During the filling of the metering container with the respective liquid, after the activation of the dose measuring device, an additional volume of the liquid is drawn into the metering tube beyond the position of the dose measuring device, wherein during this procedure and afterwards the status of the dose measuring device is checked, and a conclusion is drawn from this regarding the presence of an air bubble-free liquid in the metering tube.
