In the given work results of experiments on a hysteresis of wetting on various capillaries - cylindrical by diameter 0,8 are resulted; 2; 2,5 mm and flat in the width 1 and 2 mm. Experiments were made with various liquids (distilled water, spirit, glycerin, oil RAPS). Experiments on a hysteresis of wetting on various liquids and capillaries of different geometry have revealed, that the height of a raising of a liquid in capillaries is defined not only a superficial tension, but also the layer of adsorption covering an internal surface of a capillary. Therefore direct proportional dependence of height of a rising on a regional corner is not carried out.
