Surface Tension
Contact Angle from Surface Electro Optics What is Contact Angle? The Contact Angle is well-known technique for investigating and controlling adhesion, surface treatments and cleaning, and polymer modification. The contact angle is the angle between the tangent to the drop’s profile and the tangent to the surface at the intersection of the vapor, the liquid...
Surface Tension
Digital Surface Tension DST Series from S-EO (Surface Electro Optics) The information of surface or the interfacial tension is critically important in applications such as detergency and emulsification and is also important for many biological processes. Especially, the Du Nouy Ring method and the Wilhelmy Plate method are commonly used for measuring surface / interfacial...
Measuring Machine
This advanced thermal conductivity measurement system offers two standardized methods: (1) Vertical (ASTM D5470) for steady-state measurements (0.1–80 W/m·K) using copper pillars, ideal for low-conductivity materials like insulators, and (2) Horizontal (Angström’s Method) for transient measurements (0.1–1,000 W/m·K), suitable for high-conductivity materials like metals. The vertical method requires two sample thicknesses for accuracy but eliminates contact resistance, while the horizontal method uses temperature wave analysis for faster results without thickness constraints. Both methods feature ±0.001°C resolution, automated pressure/positioning controls, and comply with international standards, ensuring precision and reproducibility unmatched by domestic alternatives.
