The invention relates to a centrifuge for cleaning a reaction vessel unit and to a method for cleaning such a centrifuge. The centrifuge has a rotor and a rotor chamber, in which the rotor is arranged and mounted, the rotor features a receiving area for receiving the reaction vessel unit. The rotor chamber is limited by a housing, the housing having an outlet to drain the liquid discharged from the reaction vessels and being provided with an inlet for filling the rotor chamber with a cleaning solution in such a way, when the rotor rotates, the rotor 2 is at least partially immersed in the cleaning solution and distributes it in rotor chamber and/or the inlet is designed in such a way that the cleaning solution is distributed in rotor chamber when it is supplied by the rotating rotor.

The invention discloses a beverage making device that includes a brew chamber that enables a beverage brewing process. The brew chamber has a beverage outlet that lets out a brewed beverage at the end of the beverage brewing process. A rinsing procedure is performed in which the brew chamber is rinsed with water prior to or after the beverage brewing process. During the rinsing procedure, a discharge of rinsing water from the brew chamber takes place at another position on the brew chamber than a position of a beverage outlet. The other position on the brew chamber than the position of the beverage outlet is an upstream position on the brew chamber as seen in a direction of water and brewed beverage through the beverage making device associated with the beverage brewing process. The rinsing water is discharged based on a control of operation of the beverage making device.
