{"product_id":"zeta","title":"Zeta","description":"\u003cp\u003eProduct Name Zeta Product Overview English Introduction: Zeta potential analysis is a core detection technology for characterizing the electrostatic stability of colloidal and nano-suspension dispersion systems. By testing the electrokinetic potential of particles in a liquid phase system, it accurately evaluates the electrostatic repulsion, agglomeration tendency and dispersion stability of particle systems, serving as an authoritative index for judging the stability of nanomaterials, emulsions, colloids and suspensions. A higher absolute value of Zeta potential indicates better dispersion stability of the particle system with less tendency of agglomeration and sedimentation, while a lower absolute value means the system is prone to flocculation and stratification. Equipped with the British Malvern Zetasizer Lab multi-functional potential and particle size analyzer, this testing service adopts pure water as the default dispersion medium and supports customized tests under specified pH conditions (value-added detection). It is highly suitable for various water-phase nanopowders, colloidal solutions, polymer emulsions and biological suspensions. With high data repeatability and strong industry recognition, the test results are widely applied in new material modification, chemical emulsion R\u0026amp;D, biomedical preparations and environmental catalytic system stability research, and can be directly used for academic papers, patent applications, project conclusions and industrial product quality inspection reports.

The test data complies with international specifications and can be directly used for SCI papers, project conclusions, patent applications and industrial quality inspection reports. High-precision potential detection with excellent sensitivity: The potential test accuracy reaches 0.5mV, which can accurately capture subtle charging differences of the system, effectively distinguish the stability differences before and after modification, under different pH environments and different formula systems, and meet the needs of refined scientific research analysis. Dual-mode test service with flexible adaptation to demands: Provides two services including standard pure water system test and customized specified pH test. The basic package delivers high cost performance for conventional systems, while customized working conditions are available for special acid-base environment systems, fully covering various scientific research and industrial scenarios. Non-destructive trace detection with high sample utilization: Full-process liquid-phase non-destructive testing causes no chemical damage or component loss to samples. Only 3-5mg powder or 1-2mL solution is required for testing, adapting to rare, trace and high-value nano and colloid samples. Comprehensive data dimensions and intuitive conclusions: A single test outputs average potential value, distribution curve and mobility parameters, which can directly judge the system dispersion, anti-agglomeration and anti-sedimentation performance, providing intuitive data support for formula optimization, process modification and stability mechanism research. Fully automatic intelligent detection with extremely low manual error: The equipment automatically adjusts temperature, voltage and collects signals without complex manual debugging. The standardized test process ensures far better data repeatability and consistency than manual detection equipment. Transparent and standardized pricing with clear value-added services: Unified pricing for basic tests without hidden charges, and clear surcharge rules for specified pH working condition value-added services. The open and transparent charging standard allows users to select appropriate services on demand and control test costs.
