PURPOSE:To enable not only easy continuous accumulation of monomolecular films but also cleaning up of the liquid in a liquid tank by controlling the surface pressure of the monomolecular films so as to obtain desired surface density and interposing additionally a filter means in a liquid circulating system. CONSTITUTION:A circulating path 12 for a liquid and a filter means 16 are added to a liquid tank 3 contg. the liquid for spreading molecules for film forming. For example, a filter 16 which removes >=0.5mu dust is inserted into said tank. As a result, the visible dust is not admitted even after the device is used >=100 times, while in the prior art the visible dust is admitted in the tank 3 after just about 2-5 times (5-10hr in time) of use of said device. The easy continuous accumulation of the monomolecular films and the simultaneous cleaning up of the water in the water tank are made possible by the simple constitution of inserting the filter into the circulating system of the water flow path. The labor and time required for preparation for the accumulation are thus reduced. |
