The SurPASS 3 series provides fully automated zeta potential analysis of macroscopic solids in real-world situations. As electrokinetic analyzers, they use the classic streaming potential and streaming current methods to directly examine the surface zeta potential.
The zeta potential, connected to the surface charge at a solid/liquid interface, is an important metric in understanding surface characteristics and designing new specialized materials.

The SurPASS 3 series enables direct investigation of the zeta potential at the solid/liquid interface via streaming potential and current measurement. This allows access to the entire spectrum of zeta potential of technical materials, down to a few millivolts, with unparalleled reliability and repeatability. Gain fast access to surface charge data without complicated evaluation or expert knowledge.
Measuring Solutions from Tiny Particles to Large Wafers

The vast range of SurPASS 3 measurement cells covers everything. Elaborate measurement cells can handle materials of any shape, from powders and fibers to planar solids. Sample-specific measuring cells for contact lenses, hollow fiber membranes, flexible tubings, syringes, and vials enable surface charge measurement on complicated geometries.
The “plug-in and start” capability rapidly swaps measuring cells. The software automatically detects the measuring cells and shows the zeta potential.
Fully Automated Measurements in Less Than Two Minutes

The user-friendly SurPASS 3 software walks users through the measuring process and displays all essential metrics in real-time. The SurPASS 3 series gives zeta potential data in less than two minutes, allowing maximum sample throughput.
SurPASS 3 automatically enables users to investigate zeta potential's pH dependencesand displays the isoelectric point for a thorough understanding of the sample's chemistry. Liquid-on-solid surface adsorption kinetics can be monitored in real time on both model surfaces and actual samples.
Modular Setup Tailored to User’s Needs

The SurPASS 3 series is as flexible as the user’s applications. Membrane applications, biomaterials, cosmetics, detergents, and semiconductors all benefit from specialized solutions.
The user has no constraints when dealing with porous or non-porous materials, particles larger than 25 µm, granular materials, fibers, or conductive materials. The device's and measuring cells' modular design enables users to readily expand their zeta potential studies to meet future demands.
