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.
