Zeta Potential Microspheres

Polymer microspheres with controlled zeta potential for colloid science, electrokinetic separation, and particle-stability research. Lab261 produces zeta-potential-controlled microspheres across multiple polymer systems and size ranges, with characterized surface charge from highly negative through neutral to highly positive. Standard products include carboxyl (–COOH, negative) and amine (–NH₂, positive) functionalized variants, with custom intermediate charge states available. Used for electrophoretic mobility studies, dielectrophoresis, capillary electrophoresis calibration, and DLVO-theory experimental validation. Each batch ships with measured zeta potential values. Custom charge specifications and polymer combinations developed on request.

Please contact Lab 261 for beads with positive and negative zeta potential, along with preferred size, CV and quantity.
