Abstract
Abstract An analytical device for distributing equal portions of a certain liquid volume into a plurality of vessels, the device having a groove-shaped circular channel with the partially communicating vessels attached to its outer rim. Sufficient liquid is fed to the channel and allowed to overflow into the communicating parts of the vessels from where the individual portions of the liquid are forced into the non-communicating parts of the vessels by rotation of the device.
