Modular device for fixedly arranging and interconnecting individual separation units and/or function units amongst one another

A modular device for a fixed arrangement and interconnection of individual separation units and/or first functional units for performing one or more unit operations in a biotechnological process,

• wherein the modular device comprises a plurality of distributor caps, of which at least one distributor cap is provided for attachment to a separation unit and one or more further distributor caps are each provided for attachment to a further separation unit or a first functional unit,
• wherein the distributor caps each have:
• a fluid distribution means having a working connection and at least two supply or discharge connections, wherein the fluid distribution means can assume at least two defined switching positions, wherein the at least two switching positions of the fluid distribution means enable:
• a selective opening or blocking of a flow communication between the working connection and at least one supply or discharge connection;
• and/or
• a selective opening or blocking of flow communications between the working connection and a plurality of specific or all supply or discharge connections;
• connection means for establishing a flow communication between a fluid inlet or outlet of the separation unit or the first functional unit and the working connection of the fluid distribution means;
• coupling means for establishing both a rigid mechanical coupling and a flow communication with an adjacent distributor cap, wherein a rigid connector serving as the coupling means between a first distributor cap an adjacent second distributor cap establishes the rigid mechanical coupling and at a same time the flow communication between a supply or discharge connection of the fluid distribution means of the first distributor cap and a supply or discharge connection of the fluid distribution means of the adjacent second distributor cap;
• and
• an interface for manually or automatically changing the switching positions of the fluid distribution means.
