ABSTRACT:
A method for handling a microplate, in which liquid (22) is dosed into a sample well (21) and the liquid is removed and, if necessary, the sample wells are further washed and/or rinsed. According to the invention, the liquid to be dosed is dosed into the sample well (21) of the sample plate (10), after which the sample plate is centrifuged so that the centrifugal force is exerted towards the bottom of the sample well to remove air bubbles, and/or the sample plate is centrifuged so that the centrifugal force is exerted away from the bottom of the sample well to empty the sample plate. The device relating to the invention comprises a dosing device and at least one centrifuge (24). In dosing, a distributing valve (14) and a dosing nozzle (12) are usually needed, and where necessary, a vibrator device (32, 33) to bring the liquid (22) in the sample well (21) of the sample plate (10) into a motion. According to one embodiment, the vibrator device (33) comprises a needle (34) that is dipped into the liquid (22) in the sample well (21) of the sample plate (10), and by means of the vibration of the needle air bubbles can also be removed from the liquid.
