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)
