The invention is directed to an apparatus and method for feeding solution from a container with high accuracy. An embodiment of the apparatus is provided as a container hermetically containing a solution is made of a high polymer that permits the container to change its shape in accordance with the amount of its content. The container is removably connected to a tube for forming an isolated conduit extending from the container via a pump to the destination to which the solution is fed. The isolated conduit is provided with a gas-liquid separation tank for separating gas from the solution and a gas trap section communicating with the gas-liquid separation tank. The gas-liquid separation tank and the gas trap section are located between the container and the pump, and the gas trap section has a variable volume. Further, a desired number of isolated conduits may extend via respective pumps to the destination to which the solution is fed. Any one of the isolated conduits may selectively be operated by a respective gas detection sensor installed in the corresponding gas trap section. The gas trap section is preferably adapted to confine therein the gas separated in the gas-liquid separation tank, and has a variable volume, although the gas-liquid separation tank is ensured to maintain a constant volume until all the solution in the container is consumed.
