Abstract: The present invention relates to a method for the production of bodies in plastic comprising two portions hinged to each other by a single rotation pin. The method comprises the steps: a) predisposing a mold with two distinct forming chambers for the two portions; the mold comprises a third chamber for the single pin, made and positioned in such a way that the pin is formed already aligned along the hinge axis; the mold is provided with a pair of pegs axially distanced from each other to form the third chamber and sliding along the axis between a first and a second operating position; b) positioning the pegs in the first position; c) injecting plastic material inside the chambers; d) shifting the pegs from the first to the second position, bringing the pin to engage inside the seats; e) opening the mold and extracting the two assembled portions.

Abstract: A slide for use in microscopic examination of biological fluid is constituted by two plates of transparent material, one plate being a bottom and the other plate being a cover, the plates forming wells which are filled by capillarity with the biological fluid to be examined. A plurality of reliefs form a plurality of computation chambers in each well. The reliefs which define each computation chamber sectioned along a plane perpendicular to the bottom of the well have a shaped section along a profile assimilable to a polygon having at least one right angle.
