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.
An apparatus for metering a substance, having a metering head and having a metering tool releasably attached to the metering head for taking up and dispensing a substance, wherein the metering tool is configured as a cylindrical tubule having a punch slidably disposed therein, and forming a seal therewith, wherein the punch is longer than the tubule and projects out of the tubule at an upper end thereof, wherein the metering head is provided with a first gripping tool adapted to open and close for releasable clamping of the tubule and with a second gripping tool adapted to open and close for releasable clamping of the punch, and wherein the metering head is provided with a first raising and lowering device for raising and lowering the second gripping tool relative to the first gripping tool, thereby raising and lowering the punch in the tubule.
A metering tool for use in an apparatus for metering a substance, configured as a cylindrical tubule having a punch slidably disposed therein, forming a seal therewith, wherein the punch is longer than the tubule and projects out of the tubule at one of its ends.
