Force Tensiometer K100
Our universal Force Tensiometer – K100 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. High-quality components for precise measurements The principal measuring methods used by the K100 are based on the precise measurement of the force which occurs when wetting a measuring probe or a solid sample. We use a special force sensor with a particularly high resolution for the instrument in order to obtain reliable, accurate measurements, for example for determining surface and interfacial tension or contact angle. To ensure accurate measuring results, we use measuring probes such as rings and plates with highly accurate contours. This guarantees an exact correlation between measured force and the surface or interfacial tension. The software-controllabl e sample stage moves in a wide speed range and communicates its exact position to the software with a resolution of 0.1 μm. This adds to the accuracy of results where position control is essential, e.g. for Du Noüy ring or contact angle measurements. The option of saving standard positions supports you in preparing the analyses. An integral, automatic stirring function ensures optimum homogenization of dispersions before measuring or rapid equalization of concentration or temperature. The ionizer inside the sample chamber ensures reliable contact angle measurements on solid samples and single fibers. The ionizer automatically removes the troublesome effect of static charge before the measurement is carried out. Otherwise, this could falsify the result in the form of an additional force. As an addition to software control, the easy-to-use keypad for controlling the sample stage and other components such as the illumination or the stirrer, saves even more time. Thanks to the large sample chamber, the sample is loaded quickly, conveniently and safely into the instrument. Magnetically locking glass swing doors shield the sample chamber from troublesome air currents.
