Zeta-potential & Particle size Analyzer ELSZneo

Model ELSZNeo

Manufacturer: Otsuka Electronics, Japan

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.

Features

Particle size and zeta potential measurement in a wide concentration range from diluted to concentrated solution (~ 40%)
Multi-angle measurement to carry out particle size distribution with higher separability
Zeta potential measurement of solid surface in high salt concentration
Particle concentration analysis using Static Light Scattering
Microrheology measurement using Dynamic Light Scattering
Gel network and gel heterogeneity analysis by measuring intensity of scattered light and diffusion coefficient of sample at multiple points
Standard flow cell which can be used for two types of measurement (Particle size and zeta potential) without replacing samples
Wide range of measurement temperature from０to 90℃
Temperature gradient function which enables denaturation (melting temperature) analysis for proteins
Electrophoretic mobility measurement and plot analysis for accurate zeta potential measurement
Band-pass filter (option)
