Honeycomb tube

A reaction tube comprising:

• a planar frame defining a fluidic path between a first planar substrate that encloses a first side of the planar frame and a second planar substrate that encloses a second side of the planar frame;
• a fluidic interface disposed at one end of the planar frame, the fluidic interface comprising a fluidic inlet of the fluidic path and fluidic outlet of the fluidic path;
• wherein the fluidic path further includes a well chamber including a well-substrate configured with a plurality of wells, the well chamber being arranged in the planar frame between the first substrate and a well-substrate on or within the second substrate, the well chamber being in fluidic communication between the fluidic inlet and the fluidic outlet and in fluid communication with the fluidic inlet and the fluidic outlet;
• wherein the well-substrate is planar and configured with a plurality of wells that open on one-side of the well-substrate into the well chamber;
• wherein the fluidic path includes an inlet passage extending from the fluidic inlet and in fluid communication with the well chamber and an outlet passage in fluid communication with the well chamber and extending to the fluidic outlet;
• and
• wherein fluidic path further includes an intermediate channel between the inlet passage and the well chamber, wherein the intermediate channel includes a plurality of elongated channel portions connected in a serpentine manner.
