Abstract
An apparatus for determining transport characteristics across membranes and tissue sections comprises a plurality of cell blocks, where each cell block includes a pair of half-cells which hold the membrane or tissure section therebetween. A circulation path is provided in each half-cell block for exposing a fluid to one side of the membrane or tissue section. The cell blocks are maintained linearly within a base unit including a front plate and a back plate. The front and back plates are heated to maintain the cell blocks at a desired temperature.
