ABSTRACT:
A process and apparatus for the precipitation of human blood plasma components characterized in that the initial blood plasma and the precipitating agent are continuously introduced into a precipitation container in an adjusted relationship but separated with simultaneous control of the required pH values. The suspension of the individual precipitants is conveyed across a delay station and then separated. The delay station includes a flow passageway connecting the precipitation container to a separating means, with the flow passageway being so constructed as to permit substantially laminar flow of fluid therethrough. Means are also present in the flow passageway for changing the residence time of fluid therein by permitting selective variation of the length of the flow passageway.
