An automatic dynamic surface tension meter equipped with a built-in thermostat and thermometer, designed for ease of use.
The automatic dynamic tensiometer BP-D5 is a system that continuously measures dynamic surface tension from the moment the interface is formed by adopting the maximum bubble pressure method. Various controls and measurements are performed using the FAMAS software, which is also well-regarded for contact angle measurements in cooperative interfacial science. 【Features】 ○ Continuous measurement while varying the lifetime (20 to 5,000 ms) → Measurement up to 15,000 ms is possible as an option ○ Dynamic surface tension measurement at a constant lifetime is possible ○ Real-time display function of bubble pressure waveforms and LED strobe lighting function allow for monitoring the state of the bubbles ○ A series of operations from adjusting the probe depth to starting the measurement can be performed with the push of a button ○ During surface tension measurement, the temperature (°C) of the liquid sample can be recorded, allowing for temperature correction of surface tension for liquid samples with known temperature coefficients For more details, please contact us or refer to the catalog.

Company information
Our contact angle meters and surface tension meters have a wealth of delivery records and publications. We also provide equipment related to interfaces, such as friction meters, zeta potential meters, adhesive film peeling analysis devices, and LB film production devices, contributing multifacetedly to our customers' research, development, and quality control. ★ We accept commissioned measurements. Our commissioned measurements utilize high-performance equipment, and dedicated measurement personnel handle everything from measurement to reporting. We strive to provide reliable data that serves as evaluation criteria for material assessment. - Static/Dynamic/Contact Angle (wetting properties, liquid repellency, cleaning evaluation, surface free energy analysis) - Static/Dynamic Surface and Interfacial Tension (permeability, emulsification, solubility, wettability, foaming) - Lamella Length (foam stability, coating pickup, liquid drainage, wicking evaluation) - Powder Wettability (wettability of powders, wettability due to surface treatment and roughness of powders, wettability evaluation based on powder penetration speed) - Static/Dynamic Friction Wear Analysis (friction wear, lubricity, stickiness, slip properties) - Tensile Testing (adhesion, angle dependence, light peeling, high-speed peeling) - Zeta Potential (particle size distribution, dispersion stability, aggregation, sedimentation) - Anti-fogging Evaluation (degree of fogging, transparency, condensation)
