Microtrac - ZETACHECK
By measuring the electrostatic repulsion between particles, researchers can identify the stable zones of dispersions.
Powering the ZETA-check is a cylindrical PTFE beaker with an oscillating displacement piston that is used to agitate the sample. While the sample is agitated the particles are pushed towards the electrodes on each end of the piston, and a measurement can be produced in seconds.
