The measuring of the extreme corners of moistness foresees:1) horizontal fixing of the researched model of polemersc tape or membrane; 2) putting on it some drops of solution but strictly measured size; 3) keeping drops for making balance; 4) measuring the extreme corners of moistness; 5) statistic treatment of received results. The first technological scheme of the laboratory facilities consists of: 1) the horizontal table with a calibred microscrew for fixing the horizontal measures of the base of the drop; 2) the cateter which measures the vertical size of the drop (its height). The second technological scheme consist of the horizontal microscope with the photographic facilities and projection of the drop's shape on the external screen. After measuring the tangents the statistic treatment of received rezults can be made.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
