From: Rapid method for measurement of surface tension in multiwell plates
Validation of the method. Panels a–c: Comparison of data obtained by the novel optical method (———), expressed in absorbance units, with surface tension as determined directly (- - - - -), expressed in mN/m, for three detergents, C10E8 (a), DTAB (b) and AOT (c). Inset graphs show line fit plots of the two data sets. Panel d: Effect of different types of microwell plate upon the method, expressed as multiple R-values calculated by linear regression analysis. Darker outlining indicates the R-values for the selected data shown in panels a–c. Panel e: Photograph of the samples of C10E8 taken using the method shown in Figure 1a, showing the dependence of the lensing effect of the meniscus upon surface tension.
