The Adjustable Gap Cell
The elaborate measuring cells of SurPASS™ 3 suit any sample geometry, size or origin and give you the utmost flexibility for your quality control and investigations. The used measuring cell is recognized automatically.
The Adjustable Gap Cell extends the range of applications to small samples with a rectangular or disk shape. The smart cell design even enables zeta potential determination of porous materials or materials which swell strongly.
Unique and unsurpassed possibilities
- For rectangular and disk-shaped solid samples like polymer films, membranes, QCM sensors.
- Ideal for measurements on porous materials and materials which swell strongly.
|Sample size||20 mm x 10 mm|
14 mm or 15 mm in diameter
|max. 2 mm|
Detection of Native Oxide on Silicon Nitride Wafers
The zeta potential is a very sensitive parameter to detect traces of impurities on solid surfaces and their removal during surface cleaning.
Enhancement of Membrane Separation Performance
The zeta potential is sensitive to small changes in the surface chemistry and thus suitable for monitoring membrane performance.
Monitoring of Membrane Fouling with Zeta Potential
Zeta potential measurements elucidate the fouling behavior of membranes and contribute to the optimization of membrane performance.
Self-Disinfectant Surfaces - Correlation between Antimicrobial Activity and Zeta Potential
Zeta potential analysis enables the detection of functional groups introduced by additives in polymer compounds.
The Zeta Potential of Track-Etched PVDF Membranes
The zeta potential gives comprehensive information about the charging behaviour of inner and outer membrane surfaces.
Tuning of Solid Surface Properties by Self-Assembled Monolayers
The zeta potential measurement assists in tailoring the properties of technical and biomedical surfaces using self-assembled monolayers.
