A filter for preparations including a sheet form filter frame made of flexible material and a porous filter sheet, in which said filter frame has an external size suitable to set on a slide glass and is slit to form an open-sided presser part with an opening bored therethrough and parallel framing parts. The filter sheet is applied to the under surface of the presser part, passed through both slits between the presser part and the parallel framing parts and adhered on the upper surface of the parallel framing parts. When using this filter, specimens are mounted on the filter sheet which is then sheared off between the presser part and the parallel framing parts. Subsequently, the filter frame is placed on a glass slide and then removed from the glass slide so as to only leave said filter sheet with the specimens mounted thereon.
