Measurement Cell
combines particle size, zeta potential and molecular weight measurement
The Zetasizer Nano ZS, which combines particle size, zeta potential and molecular weight measurement of nano-sized particles in a three-in-one measurement system, features a fully disposable cell for zeta potential measurement. The cell can be used repeatedly if required, or discarded after a single use. The disposable cell is also suitable for particle size measurement for a range of sample types, and so allows size and zeta potential determination in the same cell. With similar dimensions to a 12mm square particle sizing cuvette, the new cell features integral gold-plated electrodes at each end of a capillary tube that has been designed as a 'U' shape for convenience and to reduce size. Its patented compact design allows zeta potential measurement of samples with volumes as low as 0.75 ml. It is easy to fill and easy to load into the instrument.
