The AcoustoSizer IIs™

AcoustoSizer IIs

The new AcoustoSizer IIs provides thorough characterization of concentrated colloidal dispersions. Directly measuring particle size, zeta potential, pH, conductivity, and temperature, it furnishes the most comprehensive analysis available in a single, turnkey instrument. Based on a flow-through sensor design, the AcoustoSizer IIs can be used in a laboratory batch analysis mode or connected directly to a process slipstream. Built-in syringe pumps provide automated potentiometric and volumetric titration capabilities for accurate isoelectric point and surfactant addition determination.
