AELAB BZY100 & BZY200 Surface Tensiometer for Liquid Interface Analysis

The AELAB BZY100 and BZY200 Surface Tensiometers are designed for accurate measurement of surface tension and interfacial tension of liquids in laboratory and industrial environments. The instruments support independent operation without an external computer and provide fast, repeatable results through automated measurement control.

The BZY Series surface tensiometers are widely used in quality control testing related to surfactants, emulsifiers, wetting agents, oils, and cleaning agents. Equipped with a high-resolution touchscreen and motorized sample stage, the AELAB BZY100 and BZY200 ensure reliable performance for routine and research-based interface chemistry analysis.

⚙️ Design & Construction

The AELAB BZY100 and BZY200 Surface Tensiometers feature a rigid enclosed frame with a precision motorized sample stage. The open sample area allows convenient preparation, while the magnetic lock air shield minimizes airflow disturbance during measurement. High-precision mechanical sensors ensure stable force detection during ring and plate testing.

🔬 Working Principle / Testing Method

The AELAB BZY Series measures surface tension and interfacial tension using the Du Nouy ring method and Wilhelmy plate method. The instrument automatically raises and lowers the sample stage while monitoring force changes on the ring or plate. Measurement programs control motion and data acquisition to ensure repeatable and interference-free testing, including manual determination of critical micelle concentration.
