Malvern Zetasizer Ultra

The Zetasizer Pro and Ultra are the ultimate companion for fast yet accurate particle and molecule sizing, particle charge (zetapotential) and particle concentration measurements, and represents the most intelligent and flexible instrument in the Zetasizer range. This powerful system has the unique capacity to perform calibration-free particle concentration measurements with ease, even deep into the nano size range. Fit to ISO 13321 and ISO 22412. Typical applications cover, inks, pigments, liposomes, micelles, polymers, carbon nano particles, gold ,biomolecules and vesicles.
