Zeta-potential & Particle Size Analyzer ELSZneo
Here's the English translation for the ELSZneo instrument:
ELSZneo: High-End Particle, Zeta Potential, and Molecular Weight Analyzer
The ELSZneo is the high-end model of the ELSZ series. This instrument accurately measures the zeta potential and particle size of both diluted and concentrated solutions, as well as the molecular weight of polymers.
As new features, the ELSZneo offers multi-angle measurement to improve the separability of particle size distribution, particle concentration measurement, microrheology measurement, and gel network analysis.
Key Features:
- Particle size and zeta potential measurement across a wide concentration range, from diluted to concentrated solutions.
- Multi-angle measurement to achieve particle size distribution with higher separability.
- Zeta potential measurement of solid surfaces even in high salt concentrations.
- Particle concentration analysis using Static Light Scattering (SLS).
- Microrheology measurement using Dynamic Light Scattering (DLS).
- Gel network and gel heterogeneity analysis by measuring the intensity of scattered light and the diffusion coefficient of the sample at multiple points.
- Standard flow cell that can be used for two types of measurements (particle size and zeta potential) without replacing samples.
- Wide measurement temperature range from 0 ∘C to 90 ∘C.
- Temperature gradient function which enables denaturation (melting temperature) analysis for proteins.
- Electrophoretic mobility measurement and plot analysis for accurate zeta potential determination.
Zeta-potential & Particle Size Analyzer ELSZ-2000 series
The ELSZneo builds on its established capabilities for zeta potential and particle size measurement by adding a new molecular weight analysis function. It offers an impressive particle size range from 0.6 nm to 10 µm and accommodates a wide concentration range from 0.00001% to 40%.
Its innovative electro-osmosis measurement allows for highly precise zeta potential analysis using a mere 130 µL disposable cell. Furthermore, a new auto temperature gradient function, with an extended range between 0°C and 90°C, enables accurate melting point and phase transition point analysis.
Key Features:
- Higher Sensitivity & Faster Measurement: Achieved with a new Avalanche Photodiode (APD).
- Thermal Analysis Capabilities: Melting point and phase transition point analysis are now possible through the auto temperature gradient function.
- Wide Temperature Range: Operates across a broad spectrum from 0°C to 90°C.
- High-Precision Zeta Potential: Enhanced by electro-osmosis measurement and plot analysis.
- Salt-Tolerant Measurement: Supports zeta potential analysis even in salt-condensed samples.
- Surface Zeta Potential: Capable of measuring the surface zeta potential of smaller area samples.

Polymer Phase Structure Analyzer PP-1000
The PP-1000 utilizes small-angle light scattering with visible light to analyze polymer and film structures in real time and on-site. Unlike X-ray or neutron-based systems, it effectively captures larger structures (μm scale) due to its use of visible light.
It supports optical anisotropy evaluation and spherulite size analysis in crystalline films via Hv scattering with polarizers, and measures polymer blend correlation lengths through Vv scattering.
Key Features
- Scattering angle range: 0.33–45° in as fast as 10 ms (100 ms with HDR)
- Analyzes submicron to several hundred micron structures
- Compatible with solution samples via specialized cells
- Easy software switch between Hv and Vv scattering
- Compact tabletop design, ideal for laboratory use
- Dynamic Measurement Capabilities
- Polymer blend phase separation
- Polymer crystallization and growth rate
- Crystal size calculation
- Molecular orientation analysis
- Aggregation and thermosetting processes
- Structural changes due to temperature or stretching*
- UV-induced curing process*
