Surface Tensiometer BP-D5

• “One-click” fully automated operation
• Surface tension against surface age (from 20 to 5,000ms) chart is computed and plotted automatically
• Measurement of the dynamic surface tension at a specific surface age from 20 to 1000ms.
• Real-time display of the bubble pressure waveform to monitor the conditions of the bubble generation
• Extrapolation of the averaged raw data according to a method suggested by Hua & Rosen
• The bubble generation from the capillary is made visible by a synchronized built-in stroboscopic lamp
• Built-in jacket type stage and platinum resistance thermometer for measurements in the range of +10 to +70℃
• Ultrasonic cleaner for cleaning of the glass probes

Hardware

• Air tank for a surface age range from 20 to 15000ms.

• Determination of the characteristics of surfactants, such as concentration, lifetime, and dynamic surface tension
• Dynamic surface tension and instant wettability of inks and coating fluids
• Determination of the absorbing rate of surfactants to control the dynamic surface tension
• Instant forming of microdroplets with regards to aerosols and emulsifiers
• Determination of instant foaming of detergents and fire extinguishing fluids
