Our Bubble Pressure Tensiometer – BP100 measures dynamic surface tension with high accuracy. It reliably analyses the mobility of surfactants, thus enabling high-speed processes such as spraying, coating, printing and cleaning to be optimized. BP100 measures the behavior of a surfactant over a wide speed range as part of a single, fully automatic measuring process. This enables you to find out how quickly a surfactant acts and when the required surface tension has been reached. In this way, the BP100 assists in the development, selection and dosing of surfactants for optimum speed

Our Force Tensiometer – K11 measures the surface tension and interfacial tension based on the force which acts when a measuring probe is wetted. The instrument features a high-quality force sensor which ensures accurate results and high reproducibility. In the interests of precision, the probes are also manufactured with highly accurate contours. Our instrument therefore provides equally reliable results for measurements carried out using the ring, plate or rod method
Our Force Tensiometer K20 is a robust, semi-automatic instrument for the precise measurement of surface tension and interfacial tension. Using the ring and plate method as the main tensiometric methods, it produces reliable measurements for the routine quality assurance of your surfactant solutions and interfacial processes
Our universal Force Tensiometer K100C performs high-precision, automatic and reliable measurements of surface tension and interfacial tension, critical micelle concentration CMC and contact angle on solids, fibers and powders. With high-quality components and a uniquely wide range of methods, the instrument carries out many tasks in the field of surfactant analysis and wetting measurement for your quality assurance or research. The simple changeover between different measuring methods takes place entirely without reconfiguring the instrument
