Assembly of fluid modules

An assembly that includes at least:

• a first fluidic module comprising a first block, the first block comprising:
• a first face of the first block, the first face of the first block configured so as to be assembled by contact with a face of another fluidic module block;
• one single central conduit opening onto the said first face of the first block or a plurality of central conduits opening onto the said first face of the first block, wherein the single central conduit or at least one of the plurality of central conduits of the first block also opens onto a face of the first block that is opposite to the first face of the first block;
• at least one lateral line connected to the single central conduit or to one of the plurality of central conduits and having at least one fluid access port on a second face of the first block not opposite to the first face of the first block, the said fluid access port being a fluid inlet or a fluid outlet;
• the said first fluidic module further comprising a first closure member configured so as to close or open the at least one lateral line;
• and
• a second fluidic module comprising a second block, the second block comprising:
• a first face of the second block, the first face of the second block configured so as to be assembled by contact with a face of another fluidic module block,
• a second face of the second block,
• a third face of the second block, and
• a fourth face of the second block, wherein said fourth face of the second block is configured so as to be assembled by contact with a face of another fluidic module block, and is opposite to the first face of the second block;
• a first central conduit with one end opening onto the first face of the second block, whereas a different end of the first central conduit does not open onto a face of the second block;
• a first lateral conduit connected to the first central conduit and having an opening on the third face of the second block;
• a second central conduit with one end opening onto the fourth face of the second block, whereas a different end of the second central conduit does not open onto a face of the second block;
• and
• a second lateral conduit connected to the second central conduit and having an opening on the third face of the second block;
• the said second fluidic module further comprising a second closure member configured so as to close or open the opening of the first lateral conduit on the third face of the second block and/or the opening of the second lateral conduit on the third face of the second block;
• wherein the first face of each of the first and second fluidic modules is assembled with a face of a block of another fluidic module by contact between the two faces and
• wherein the single central conduit or at least one of the plurality of central conduits of the first block is aligned with one of the first and second central conduits of the second block.
