ELSZneo is the high-end model of the ELSZ series. This instrument measures zeta potential and particle size of both diluted and concentrated solutions, and molecular weight of a polymer. As new features, ELSZneo provides a multi-angle measurement to improve the separability of particle size distribution, particle concentration measurement, microrheology measurement, and gel network analysis.
The zeta potential flat surface cell adopted a newly developed coating which enables measurement in a high salt concentration such as physiological saline. With the brand-new flat surface cell and ultra-micro volume cell that can measure particle size with a 3 μL of sample, ELSZneo is expanding the potential in the life science field
