A self-contained disposable package including a container of diazo copy developer liquid and an ammonia vapor absorber canister is disclosed for use with diazo type copy machines. The container of developer liquid and an absorber canister are adapted to be readily hooked into the supply and exhaust lines of the copy machine developer chamber and to the exhaust line of a machine degassing chamber. The absorber canister includes a quantity of ammonia vapor absorber material such as a mixture of excelsior and activated carbon, both treated with phosphoric acid, into which is extended a flow tube adapted to be connected to the degassing exhaust chamber with the exhaust flow directed to emanate from the lower region of the canister an flow upwardly through the absorber material and then out through openings in a top cap. The construction of the canister minimizes flow channelization through the absorber material.
