A stopped-flow apparatus is disclosed which includes one or a pair of flow systems mounted in separate thermostatically controlled baths and actuated by a single driving system thus permitting differential rate of determinations. The reaction or observation cell is easily changed to modify the apparatus without the necessity of changing the entire flow system. This is accomplished by screw threaded connection to the cell so that a variety of different cells can be inserted readily and easily into the thermostatically controlled bath. Stopping is accomplished by means of an adjustable block system on the main driving system or by a stopping syringe operatively connected to the cell. Efficient mixing is accomplished in a mixing chamber screw threadably secured to the cell and utilizing a double bifurcated feed block.
