Applications
Surface tension testers are widely applied in scientific research, industrial production, and quality control fields. Their main applications include:
- Materials Science: Measuring surface tension of liquids like coatings, inks, and adhesives, and evaluating their wettability and spreadability.
- Chemical & Petroleum: Analyzing surfactant performance and crude oil interfacial tension to optimize process flows.
- Pharmaceutical Industry: Testing surface tension of solutions to ensure stability and dispersion.
- Food Industry: Researching surface characteristics of emulsifiers, beverages, etc., to improve product quality.
- Biomedicine: Measuring surface tension of biological fluids (e.g., blood, cell culture media) to assist in disease diagnosis and research.
Key Features
- Adopts advanced strain or electromagnetic force balance sensor, featuring high precision and excellent repeatability.
- Digital tube display mode for real-time display of current weight and surface tension value.
- Integrates both platinum plate and platinum ring test methods, allowing single or simultaneous selection.
- Real-time collection of surface tension values with full-process curve recording.
- Convenient lifting bracket for platinum plate and ring, enabling easy loading/unloading.
- One-key peeling function ensures stable readings without zero drift or numerical jumps.
- Smooth ball screw lifting system operates noiselessly with stable up/down speeds.
- Provides data collection and management software.
- Complies with multiple international standards including GB/T6541-86, ISO1409-1995, and others.
