Homogeneous Reactor

The YanZheng Instrument Homogeneous Reactor is a laboratory- or industrial‑grade reaction device used in fields such as chemistry, pharmaceuticals, and food processing. It is primarily employed for chemical reactions, synthesis, catalysis, and other processes conducted under homogeneous mixing conditions. Through efficient stirring, temperature control, and a sealing system, the reactor ensures that reactants are thoroughly mixed in a uniform phase—such as a liquid phase or a gas–liquid phase—thereby enhancing reaction efficiency.

Tri-element precursor reactor

The co-precipitation reactor for ternary precursors is a core piece of equipment in lithium-ion battery production. The automated pH-controlled co-precipitation reactor for ternary precursors has undergone further improvements in areas such as stirring, gas protection, and overflow mechanisms. When the reaction feedstock enters the reactor, it mixes rapidly and exhibits excellent dispersion, resulting in uniform elemental distribution, strong solid-solution homogeneity, good sphericity, and technical performance metrics—including tap density—that all meet superior standards. The size of the reactor vessel can be customized according to specific requirements. The reactor interior can be equipped with either 2D or 3D cameras to capture real-time images of the material’s forming process.

All‑transparent, visible high‑pressure reactor

Shanghai Yanzheng Company has meticulously crafted a fully transparent high‑pressure reactor, utilizing two exceptional materials: sapphire, as hard as stone, or pure, crystal‑clear quartz glass—both boasting outstanding pressure resistance, capable of withstanding up to 10 MPa (sapphire) or 2 MPa (quartz glass), offering users a wide range of options. Customized, non‑standard services further expand its application scope. This equipment employs magnetic coupling mechanical stirring technology, achieving static sealing with zero leakage, thereby ensuring the purity and safety of experimental processes. This reactor not only boasts a unique charm thanks to its all‑transparent design, but also excels in its excellent light transmission, allowing a clear, unobstructed view of reaction processes under high pressure. Throughout the experiment—from initial ingredient preparation to final product formation—the temperature remains fully controllable, while the observation window enables users to take samples for analysis at any time or conduct meticulous observations of multiphase behavior. In addition, it is well suited for the spray preparation of supercritical particles, in-depth investigations of thermodynamic properties, and precise monitoring of long‑term dissolution processes.
