Abstract
An apparatus for the gravimetric calibration of multi-channel pipettes contains a balance that has a load receiver configured to support receptacles containing a substance to be weighed. The apparatus has a holder device to support a certain number of the receptacles into which a test liquid is dispensed from the multi-channel pipette. The apparatus further has a transport device for advancing the holder device towards the load receiver. The receptacles are seated in the holder device at equally spaced positions and are one by one delivered to and subsequently removed from the measuring device.
