Condition: good (used), Features: • Accurate, Rapid, Easy to Use • No Cell Alignment or Calibration Pgedpfx Adeupafvelek • Temperature Control, 5 - 75° C • Customizable Reports, SP Charts, Two-Parameter Plots, Graphical Overlays • Integrated Computer The Brookhaven ZetaPlus is designed for rapid, accurate and, above all, straightforward determination of zeta potential and electrophoretic mobility of fine particles from around 5nm up to about 50µm. Its principle is the measurement of the Doppler shifted frequency spectrum of scattered laser light using a known reference frequency for maximum accuracy. The key attraction of the ZetaPlus is its simplicity of operation due to the innovative design of its sample cell – electrode assembly. Using low cost, disposable cuvettes and simple "plug-in" electrodes, it completely eliminates the problem of electroosmosis – for all samples. With this system, cell alignment with respect to the laser beam is no longer critical and therefore requires no periodic checking or adjustment. Bubble-free filling of the cell is easy and fast and the volume of sample required is minimal. Sample temperature is accurately controlled by a fast response dual-Peltier system operating in the range 50C to 750C. For most common liquid media, necessary physical constants are all pre-programmed throughout the temperature range. pH can be read directly into the ZetaPlus software. Zeta potentials can be automatically plotted against pH or any other variable of the user’s choice, such as surfactant or additive concentration.
