  • Patent number: 11291968
    Abstract: The invention refers to a reactor and a method respectively for performing, by means of solid reaction members, a biological or chemical transformation, or physical or chemical trapping from, or release of agents to, a fluidic media, and a subsequent cleaning of the reactor, said reactor comprising a vessel (11) in which a transformation device (100) has been mounted. The invention also refers to a reactor kit comprising such reactor. The reactor comprises at least one nozzle (15) arranged on the longitudinal inner wall of the vessel (11). The at least one nozzle (15) is arranged to direct a flow of a cleaning fluid (CF) in a direction towards a longitudinal centre axis (L1) of a flow distributor (1) arranged in the vessel (11).
