| Abstract: | The continuous record of the apparent weight of a membrane-bounded small vessel immersed in a solution of different density as compared to that inside it, offers a cheap and reliable possibility to measure osmotic flows at 10?5 kg · m?2 · s?1 sensitivity. The method equally applies for diffusional (isotopic) water flows. |
