[Apparatus for studying the surface properties of pulmonary extracts]. 1975

Biul'EV

The author describes a unit for studying the surface properties of the pulmonary extracts by Wilhelmy's principle; the unit consists of a two-coordinate self-recorder, compensatory amplifier, modified Wilhelmy's balance, a rectifier and a stabilizer. The unit permits automatic recording of the dependence of surface tension of the extract upon the area of its surface.
