ABSTRACT:
An apparatus for generating a continuous solution gradient wherein solutions of differing concentrations are layered in a tube and the tube disposed at an angle with respect to the vertical and is rotated for a predetermined period of time thereby to generate a continuous solution gradient, i.e. continuous variation in concentration between the concentration of the initial solutions.
