Feed rings and positioning tool. (A) Punched transparent ring without glucose crystals. (B) Punched white ring with encapsulated glucose crystals. (C) Punched transparent ring without glucose crystals sprayed with black lacquer. (D) Tool to position the polymer rings in the wells of a microtiter plate. (E) Illustration of the well geometries with a positioned feed ring. Ring configuration is determined by the ring inner diameter (dinner), the height of the ring (Zheight) and the vertical position of the ring in the well (Hposition). (F) Schematic view of how the positioning tool is applied to position a polymer ring in a well of a microtiter plate
