Abstract

A metering apparatus including a scale on which a metering head is disposed in such a manner that the scale measures the weight of the metering head, and a metering tool for taking up and dispensing substance, attached to the metering head. The metering tool is configured as a glass tubule having a glass punch slidably disposed therein, forming a seal. The metering head is provided with a first gripping tool for clamping the glass tubule in place and with a second gripping tool for clamping the glass punch in place. The metering head furthermore has a raising and lowering device for raising and lowering the second gripping tool relative to the first gripping tool, such that the glass punch can be raised and lowered in the glass tubule of the metering tool.
