Field ESA Options
optional extensions for the Field ESA
Viscometer
The Viscosimetry Option is operated as a Stand Alone Version or in conjunction with a Combined Zeta - Visco - Cell (see picture).
| Shear Rate | 10 to 1000 1/s |
| Viscosity Ranges | |
| Stand Alone Version | 0,1 to 100mPA*s |
| Combined Cell Shear Rate | 0,02 to 20Pa*s |
| High Viscosity Cell | 1 to 100Pa*s |
Non-Aqueous Systems
This option is characterised by a very high measurement sensitivity which enables a directly, very accurate and reproduceable measurement of zeta potential in apolar media.A very flexible software accepts different calibration standards.
Flocculation
The flocculation cell is used to investigate the particle flocculation at small sample concentrations (wastewater) and zeta potentials. Sedimentation profiles give valuable informations about the efficency of different flocculants and permit a rapid and accurate optimization of the flocculation processes.
Surface Acoustic Potential
The SAP Membrane Zeta-Meter measures zeta potential of filter membranes directly under real sample conditions. It is extremly easy to use, compact and portable. The automatic titration determins quickly and accurately the isoelectric point. As an alternative the instrument can be used without PC for data logging over 2 days; this makes it suitable also for industrial environment use.
