1. Surface Energy analyzer.
Why do you need Surface energy & Contact Angle testing?
Water droplets bead up on a surface instead of spreading, leading to poor cleaning or coating performance.
Liquid does not wet surgical implants properly.
Microfluidic devices show poor fluid flow due to improper surface wettability.
A paint coating peels off from a metal or plastic surface because the surface energy is too low for proper adhesion.
A PVD coating cracks because of poor adhesion between the substrate and coating material which can be enhanced by proper surface treatment of the substrate.
So, if you face similar problems than surface energy analyzer can give you the solution for it.
SURFACE ENERGY ANALYZER (SEA-01) uses advanced contact angle measurement techniques to precisely determine the surface energy and wettability characteristics of your samples. This method provides quantitative, reproducible, and objective data, enabling reliable evaluation of surface quality.
Contact Angle vs. Wettability vs Surface Energy
As the contact angle increases, wettability decreases.
Low Contact Angle (< 90°): Indicates high wettability. The liquid spreads across the surface, often seen on hydrophilic (water-loving) materials.
High Contact Angle (> 90°): Indicates low wettability. The liquid "beads up" into droplets, characteristic of hydrophobic (water-repelling) surfaces.

𝛾𝑠g: Solid-gas tension
𝛾𝑙g: Liquid-gas tension
Surface Energy vs. Contact Angle Higher surface energy typically leads to a lower contact angle. High Surface Energy: The surface has a strong "pull" or attractive force, overpowering the liquid's internal cohesion and forcing it to spread out. Low Surface Energy: The surface lacks the energy to attract the liquid molecules strongly, allowing the liquid to maintain its droplet shape.
Surface treatments like plasma or chemical coatings can be used to increase surface energy for better adhesion. Better adhesion when surface energy is high.
