Description
The Zeta Potential Analyzer ZPA 20 uses the patented bidirectional oscillating streaming potential analysis to measure the zeta potential of fibres, powders and plate shaped solid materials. Applications that depend on the adhesion between solids, the adsorption and chemical reaction of ions/molecules, surfactants, polymers etc. can all benefit from investigating the zeta potential and its changes depending on the pH value.
The Zeta Potential Analyzer ZPA 20 is a compact measuring instruments that utilizes the patented bidirectional oscillating streaming potential method. It is designed to measure the zeta potential of various macroscopic solid samples with highest accuracy and within shortest time.
Main features:
- patented bidirectional oscillating streaming potential method
- powerful stepping motor for oscillation frequencies of up to 0.5 Hz
- measuring probes for voltage, current, conductivity, pH value, pressure and temperature
- measuring duration for a single zeta potential typically under 1 minute
- optional liquid dosing unit LDU 25 for automated pH value changes
- measuring cells for fibres, powders & granulate materials or for plate shaped solid materials
