PS: It is primarily used for auxiliary testing and preliminary screening. Its measurement results can serve as corroborative data for judgment, but cannot be used as the sole or final basis for decision-making.

Product Details
The ring method measures the surface tension of a liquid by measuring the force required for the platinum ring to detach from the liquid surface.
Application scenarios
1. Development and Quality Control of Daily Chemical Products
Shampoo/shower gel: The lower the surface tension, the stronger the cleaning power
Stability of lotion: oil-water interfacial tension affects emulsification efficiency
2. Pharmaceuticals and biomaterials
Compatibility of injection: The surface tension should be close to blood to avoid hemolytic reactions.
Pulmonary surfactant: simulates the surface tension of alveolar fluid (normal value 25-30 mN/m), used for drug development of respiratory distress syndrome.
3. Food industry
Beer/carbonated beverage: surface tension affects the stability of foam.
4. Petroleum industry
Oil displacement agent screening: reduce oil-water interfacial tension and improve crude oil recovery rate.
Fuel additive: Low surface tension promotes atomization and reduces engine carbon deposition.
5. Materials Science
Wettability study: Calculate the critical surface tension of solids through surface tension and predict coating adhesion.
