A discharge device (30) for centrifuging a reaction vessel unit comprising reaction vessels, for example a microtiter plate, is proposed, as is a corresponding centrifuge and a method for cleaning the discharge device (30). The discharge device (30) has a discharge plate (31), which can be arranged in a centrifuge opposite the openings of the reaction vessels. During the centrifuging, liquid exiting the reaction vessels owing to the centrifugal acceleration is collected by the discharge plate (31) and discharged. Fins (40) which are arranged approximately parallel to the axis of rotation of the rotor and transverse to the movement direction of the discharge plate (31) are present on that side of the discharge plate (31) which faces towards the openings of the reaction vessels. The discharge device (30) keeps liquid that is ejected from the reaction vessels during the centrifuging away from the rest of the device. The fins (40) ensure that ejected liquid is optimally discharged. Corrosion and / or chemical interactions with the ejected liquid are prevented, and the formation of aerosols is also greatly reduced. Cross-contamination of reaction vessel units during the centrifuging is largely prevented, as is the wetting of the reaction vessel unit. Furthermore, the cleaning effort is considerably reduced.
