Stalagmometr ST-2 is designed to determine the surface tension of surfactant solutions by determining the amount of drops is squeezed out at the borders: the solution – SAW antipolyarnaya liquid or solution – SAS – air. Stalagmometriya – method of separation of drops is common in medical and pharmaceutical practice. The theoretical justification of this method is as follows. Formation of drops of liquid at flowing out of her small holes is the result of surface tension and gravity. For example, if the set of vertical tubes with a narrow capillary bore liquid seeping slowly, then at the end of the tube is formed slowly increasing in size drop. Increasing in size, the drop off when its weight becomes equal to the resistance to rupture the surface film, which supports the drop. Before the separation of drops at the end of the tube is formed constriction at which separation occurs drops.

Stalagmometr a glass tube with an extension of the middle and the bottom of the capillary, the extended portion is bounded by two marks. Put the tube in a beaker with test solution, using a rubber bulb delaying a solution to the instrument (the fluid level should be above the upper mark) and give a liquid drop by drop flow from stalagmometra in the cup. The exhaust velocity can be adjusted using a screw clamp. When the liquid level reaches the upper mark, start counting drops, counting continues until the bottom level of the label. Stalagmometr ST-2 is designed to determine surface tension of surfactant solutions by determining the amount of drops is squeezed out at the borders: the solution – SAS – antipolyarnaya liquid or surfactant solution – air.
