The distilled water transfer through a bentonite membrane into a vessel with tritium (HTO << H2O) and deuterium (99.84% of D2O)) water has been experimentally studied. The phenomenon of isotopic osmosis is observed in the series of experiments. It is shown that this effect is caused by the difference in the hydrogen isotopic composition of water in two conjugated vessels. The values of the rate constants and the osmosis pressure are assessed.
