TRACKER software

Control and monitor experimental parameters: volume, temperature, pressure, time

Real time measurement and display: surface/interface tension (0.01-1000 mN/m/± 0.01 mN/m)

Real time measurement and display: Contact angle (0-180 °/± 0.1 °)/Contact angle measurement automatically determines baseline

Measurement of interface expansion rheology:

||Oscillation frequency: 0.001Hz-2Hz

||Droplet volume change: ± 0.1 µ l - ± 100 µ l

||Volume change rate: 0.01 µ l/s -20 µ l/s

||Time: The area of droplets or bubbles remains constant during oscillation for several hours, including at the gas-liquid interface

||Calculation of Viscoelastic Modulus and Stiffness Coefficient
