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.

This invention discloses a gene sequencing pipetting assembly, including a pipetting module and a cleaning assembly. The pipetting module includes a reagent compartment for storing reagents, a reagent needle assembly for drawing or injecting reagents, and a pipetting drive assembly for driving the movement of the reagent needle assembly. The reagent needle assembly includes a reagent needle and a pipetting pump connected to the reagent needle. The reagent needle draws reagents from the reagent compartment and injects the reagents into a flow cell assembly under the action of the pipetting pump. The cleaning assembly includes a cleaning tank for storing cleaning solution, an inner wall cleaning unit for cleaning the inner wall of the reagent needle, and an outer wall cleaning unit for cleaning the outer wall of the reagent needle. This invention also proposes a gene sequencing system and a gene sequencing pipetting method. The gene sequencing pipetting assembly, pipetting method, and gene sequencing system of this invention utilize a reagent needle to transfer all reagents, which not only effectively simplifies the structure but also facilitates cleaning.
