Fig. 1From: An inexpensive open source 3D-printed membrane feeder for human malaria transmission studiesAssembly and operation of the 3D-printed membrane feeder. a The membrane feeder was designed in two parts, a top chamber that connects to a circulating water bath and a bottom chamber holding a water reservoir and the RBC/gametocyte/serum sample on the underside. b Both pieces are glued together into a single, watertight unit. c When in operation, circulating warm water maintains the temperature of the gametocyte-infected blood sample that is injected through access holes and sits between a layer of stretched Parafilm® and the underside of the feederBack to article page
