Abstract
A device for filling and suction of filter plates in a microtitration plate format which is comprised of a simultaneously working multipipette, two stacking elements, a plate transfer car with a suction station, four lifting drives, and an electric plate holder. The plates emanating from the dispensing stacking elements are filled by the pipettes or the pipette automatic machine and can be deposited on the suction station afterwards with the aid of the plate holder and the lifter. The plates are then lifted together with the weight such that the plate is sufficiently pressed hard on the seal in the suction station. As a result, a corresponding low pressure can be generated in the vacuum station.
