<p>An electrophoresis device (30) is disclosed which separates cells, particles, proteins, and other separands by collecting samples of decreasing electrophoretic mobility in a train of inverted collection cavities while an electric field is applied between said inverted cavities and one or more sample cuvettes containing a mixture of cells, particles, proteins or other separands. One circular plate (40) is provided for the one or more sample cuvettes, and one circular plate (38) is provided for the train of collection cavities. The invention utilizes an innovative purification method that combines free electrophoresis and multistage extraction in an instrument capable of separating living cells, particles, and proteins in useful quantities at high concentrations. The purification method includes a method for dealing with electrolysis products, a technique for controlling the electrical energy input, and an approach for keeping the process isothermal. The invention solves many separation applications problems on earth and also in reduced gravity in space flight.</p> |
