A storage canister for process liquid includes a receptacle having a top side formed with two apertures. The receptacle houses two leakage proof pouches of elastic material each having an opening closed by a control valve. An upper part of respective valve housing projects through the aperture and is secured thereto while the lower part of the valve housing within the corresponding pouch extends up to the bottom of the receptacle. The pouches are arranged one above the other between the top cover and the bottom of the receptacle and being extendable to such an extent that their combined volumes correspond approximately to the volume of the receptacle. Preferably, the receptacle has the form of a flat parallel epiped so that a plurality of equal storage canisters are inserted into a drawer of wet processing apparatus and the normally closed control valves are activated by suction or by over-pressure from suction or pressure devices in the processing apparatus.
