SurPASS 3 determines the zeta potential at the surface of a macroscopic solid in contact with an aqueous solution. The compact instrument design with plug-in sample holders gives easy access to material surface charge to everyone – from scientists in academia to technicians in industrial labs.
With SurPASS 3, Anton Paar has achieved another milestone in the company’s efforts to commercialise the surface zeta potential method for material characterisation.
The compact design of SurPASS 3 is one of the most obvious improvements. Within this instrument Anton Paar combines a proprietary method for liquid transport with a higher time resolution for collecting measuring data. This enables a better sensitivity for the zeta potential analysis at a significantly shorter measuring time.
For the first time, SurPASS 3 offers the determination of the isoelectric point at a single click. Mounting sample holders was never that easy. The measuring cell in use is automatically detected by the SurPASS 3 software.
With the extension to higher applicable pressure SurPASS 3 opens up new applications in the fields of membranes, biomaterials or semiconductors.
