(54) Sealing device for analytical slide


(57) A sealing device for analytical slide encasing a multilayer analytical element within a frame having an opening on each of upper and lower surfaces thereof for use in a process for analysis of a liquid sample comprising steps of applying the liquid sample onto the analytical element, incubating the element and detecting a reaction occurring in the element, said sealing device being to be so arranged adjacently to the analytical slide as to substantially cover the surface of the element on which the liquid sample is applied, for serving to reduce evaporation of the liquid sample from the analytical element during the incubation step, characterised in that at least a part of the surface of the sealing device to face the surface of the element on which the liquid sample is applied is made of an inert material such as a fluorine-containing polymer.
