Dynamic Surface Tensiometer 【BP-D5】

This special-use surface tensiometer measures the dynamic surface tension of surfactant solutions, using the maximum bubble pressure method. All the measurement processes are performed automatically with a single click on the start button.
What is Surface Tension?


square Elapsed time and surface tension lifetime charts are computed and plotted automatically
square Real time display of bubble pressure waveform to monitor conditions of bubble generation
square Applies the Rosen fitting technique to present maximum slope of surface tension lowering ability
square Built in jacket type stage and platinum resistance thermometer
square The bubble generation from the capillary is made visible by synchronized built-in stroboscopic lamp
square Ultrasonic cleaner for capillary cleaning is included
