Research group:
CF: CEITEC Nano
Description:
The ZetaSizer Ultra from the Malvern company provides the ability to measure the size and zeta potential of particles, molecules or micelles in a liquid medium. The unique features of the ZetaSizer for measurements over a wide concentration range and precise temperature control give reproducible, repeatable and accurate results. This device utilizes Multi-Angle Dynamic Light Scattering (MADLS®) technology for the highest resolution of sizing data.
The ZetaSizer works in the sample temperature range of 0–120 °C. The minimum sample volume is 3 μL for the particle size and 20 μL for the zeta potential measurement. The minimum sample concentration for particle size measurement depends on the technique used, starting from 0.1 mg/mL for Dynamic light scattering (Non-Invasive Back-Scatter) to 1 mg/mL for MALDS, the same concentration as for zeta potential. The size range is 0.3–10 μm for size determination and 3.8 nm–100 um for zeta potential measurement.
