Abstract
An assay device in which to carry out a fluid-phase chemical assay, comprising means for supporting a test substrate, a sample chamber for receiving a fluid sample and at least one fluid control device for controlling the movement of fluid into and/or out of the sample chamber, wherein the fluid control device comprises a fluid outlet chamber in fluid communication with the sample chamber, and a displaceable flexible diaphragm the displacement of which alters the volume of the outlet chamber so as to allow and/or restrict fluid flow between the outlet and sample chambers. The invention also provides assay apparatus incorporating such a device, an assay station for use as part of such apparatus, a fluid control unit for use as part of the assay device and a method of conducting an assay which may involve the use of such apparatus and devices.
