A80 Series Surface Tension and Interfacial Tension Meters are fully automatic dynamic and static interfacial chemical analysis systems based on the weighing method. They are specifically designed to meet the needs of a wide range of users for research and development, as well as high-quality and high-precision testing during interfacial chemical testing. These instruments can be used to measure surface tension (ST)/interfacial tension (IFT), contact angle (CA)/hydrophilic angle (DCA)/wetting angle of solid materials, powders, and fibers, and the analysis of solid surface free energy (SFE). They also determine critical micelle concentration (CMC) and other key indicators that characterize interfacial chemical properties in the preparation of surfactants.
The instrument employs high-speed (92 Data/S) microbalance analytical technology (one ten-thousandth precision) and a high-precision positioning platform controlled by stepping motors (precision vertical travel positioning).Ning Stage) and digital semiconductor temperature sensors, offering higher measurement accuracy, faster speed, more sensitive response, and precise positioning with a resolution of 0.007um.
The A80 series features the CAST®1.0 software module for interface chemical analysis based on weighing principles. The main software module, SM01, incorporates three different surface/interfacial tension testing principles: the third-generation Young-Laplace semi-circular plate method (Modified Wilhelmy Plate method), the platinum ring method (DuNoüy Ring Method), and the classical platinum plate method (hanging plate method, classical Wilhelmy Plate method). It boasts powerful data management capabilities and is suitable for testing key indicators such as high viscosity (10,000CP), dynamic surface/interfacial tension, surfactants and their micelle concentration (CMC). Optional contact angle analysis module SM02 and other software modules further enable testing of dynamic/static surface tension, interfacial tension of liquid materials, contact angles of solid materials, and various complex applications such as contact angle using the Wilhelmy Plate method, single fiber contact angle, and powder contact angle by the modified and extended Washburn method. Additionally, it measures the free energy and its components of solid surfaces (dispersive forces, polar forces, hydrogen bond values, etc.), density and sedimentation velocity, single fiber tensile strength, sediment particle size, and other quantities, as well as Langmuir-Blodgett films, analytical balances, thermal analysis, and water absorption analysis.
The A80 series, based on the principle of weighing method and at the level of interface chemical analyzers, offers a significant advantage, providing researchers with a comprehensive solution for interface chemical measurements.
