Bubble pressure tensiometer BP100

for surfactantdetergentfor wetting agents

The BP100 Bubble Pressure Tensiometer analyzes the mobility of surfactants based on the dynamic surface tension (SFT). This allows you to find out how quickly surface-active substances such as detergents or wetting agents achieve the required reduction of the SFT. With the help of this information, you can optimize formulations for dynamic processes such as spraying, coating, printing, or cleaning. Applications • - Use of surfactants in spray processes • - Formulation and optimization of detergents for washing and cleaning processes • - Wetting agents for coating and printing • - Surfactant research and development Measuring methods • - Dynamic surface tension using the Laplace pressure of a gas bubble at a capillary in a liquid Measuring results • - Dynamic surface tension (SFT) as a function of surface age • - Time-dependent SFT at a constant surface age • - Adsorption coefficient and diffusion coefficient • - SFT of the solvent and the equilibrium SFT (extrapolation in accordance with Hua & Rosen) • - Temperature of the liquid
