Dynamic Surface Tensiometer: BP-D5
The BP-D5 is a specialized instrument designed to measure dynamic surface tension at very short surface ages, capturing surfactant behavior under real process conditions such as spraying, coating, printing, and foaming.
Key Features:

Maximum Bubble Pressure Method
• Measures surface tension from 20 ms to 5000 ms surface age
• Captures surface tension before surfactant equilibrium is reached
• Provides direct insight into adsorption kinetics
This method reflects real-world conditions far better than static measurements.
