A multi-unit, dynamic flow, inhalation exposure system which is capable of accommodating 12 mice per unit has been described. Components of the system include a mixing board, one or more glass distributing tubes, and detachable glass chamber tubes. The flow of a specified concentration of test gas exits from the mixing board, enters a distributing tube, and is then distributed equally to 12 chamber tubes housing one mouse each. Advantages includes quick equilibration time (10 min), relatively low flow rates (20 l/min per distributing tube), ease of disassembly for cleaning, compact size, modest expense and minimal temperature, pressure and physico-chemical effects.
