Device for performing a chemical transformation in fluidic media

A device for performing biological or chemical transformation, or physical or chemical trapping in fluidic media comprising:

• a. a hollow tubular flow distributor having at least one central fluid medium inlet, at least one peripheral fluid medium outlet, and at least one confinement wherein said transformation or trapping is performed;
• and
• b. a means for rotating, rocking, wagging, or oscillating the device,
• wherein the at least one confinement of the flow distributor houses one or more solid members that participate in or facilitate(s) a biological or chemical transformation involving at least one agent distributed with the flow, or causes said agent to become physically or chemically trapped by the one or more solid members, and
• wherein the at least one confinement is in a form of two or more confinements that are connected in parallel and that are filled with different solid members capable of carrying out different chemical transformations.
