Abstract
A microprocessor-based, control unit for analysis of a fluid sample, and for especially biomedical analysis of a body fluid, is provided. Also provided is the combination of a roller assembly and a compartmentalized pouch containing certain chemicals, with the rollers functioning to break rupturable seals of compartments and to push fluids from one compartment to another. Apparatus in accordance with the present invention, is useful, for example, in monitoring urea concentration during dialysis.
