ABSTRACT:
A liquid containing plasma proteins in solution and a liquid precipitant are intermixed by projecting through space a pair of convergent solid jets of respectively the solution and the precipitant so that the jets combine and the liquids thereof intermix, plasma protein being precipitated instantaneously on intermixing of the liquids and being subsequently separated from the liquid mixture; by creating miniature jets, especially jets with diameters in the range 0.5mm to 2mm, the intermixing can be effected in a small confined space whereof the temperature can be closely controlled to prevent denaturation of the mixture, intimate intermixing of the liquids can be attained practically instantaneously in said space, and jet flow can be transformed to film flow without denaturation of the mixture by foaming or turbulence.
