Zetasizer Nano ZS (Malvern)

This equipment can provide information about the size and the colloidal stability (if it’s based on electrostatic repulsion) of particles, vesicles, micelles, proteins, etc. that are suspended in a liquid medium. Applications: determination of the size (0.6nm to 6μm) and zeta potential (for particles whose sizes are between 5nm to 10μm) of colloids.

A micro volume (12 μl) quartz cell for DLS and an universal dip cell for the determination of zeta potential in organic solvents are available.
