摘要： An apparatus for producing a highly uniform mixture of a first solution with two or more solute-containing solutions comprises a reaction vessel with a porous member located therein. The porous member, whic may be a membrane or a plurality of fine tubes, is located within the vessel below the surface of the first solution. One or more solute-containing solutions are rapidly and uniformly introduced into the first solution through the porous member. The solute containing solutions diffuse rapidly into the first solution through the openings in the porous member, mixing evenly to produce a uniform composition.
