Abstract

An apparatus for metering a substance into a target container includes a gripping tool, with which a metering tool can be picked up and released, and a scales. The metering tool is configured as an adhesive body which is wetted by a substance so that a small amount of substance measurable by the scales remains adhering to the metering tool. Once the desired amount of substance has been picked up with the metering tool, the latter, including the substance adhering thereto, is released into the target container. A controller controls the scales and the gripping tool and decides whether the amount of substance picked up by the metering tool is usable or whether more substance should be picked up or whether the metering tool should be discarded and somewhat less substance picked up with a fresh metering tool.
