PURPOSE: To have a large filtration surface by providing a dissolution cell with a tubular filter.
CONSTITUTION: A vessel 1, which is closed at the bottom end part 4 and is opened at the top end part 5, is provided with an inlet means 9 for a liq. and a conical zone 6 incorporating packings 10 for dispersing the liq. Then, a cylindrical first zone 7 is connected to a cylindrical second zone 8 having a larger section area than that by a shoulder part 11 and a dissolution chamber 24 is formed by the zones 6, 7. Further, a stopper 2 provided with an outlet means 15 for a soln. is attached to the top end part 5 in a liq. leak-proof condition. Then, a filtration means 3 held between the stopper 2 and the shoulder part 11 is formed by the tubular filter 20 and is arranged within a soln. path between the dissolution chamber 24 and the outlet means 15. Consequently, it is possible to provide the large filtration surface.
