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.
