Abstract
A dissolution cell for determining the kinetics of dissolution of a solid substance in a particular liquid, includes (a) a housing receptacle having a closed bottom end and an open top end, an interior of such receptacle defining (i) a lowermost upwardly diverging conical zone provided with liquid inlet means extending from a tip of the conical zone through the bottom end of the receptacle, (ii) a first essentially cylindrical zone surmounting the conical zone and (iii) a second essentially cylindrical zone surmounting the first essentially cylindrical zone, having a cross-sectional diameter greater than that of the first essentially cylindrical zone and being in communicating relationship therewith, such conical zone (i) and such first essentially cylindrical zone (ii) defining a chamber for the dissolution of a solid substance in a liquid solvent, (b) a closure leak-proofedly secured to the open end of the receptacle and provided with a solute outlet means, and (c) filtration means secured between such closure and an area of communicating relationship between the first and the second essentially cylindrical zones, so as to be disposed in a pathway for the solute extending from the dissolution chamber to the solute outlet means.
