Elevating High-Pressure Reactor

The touch screen offers simple, intuitive operation with a clear user interface, eliminating the mechanical and cumbersome issues associated with traditional button-based controls. It can record and collect all real-time data and display it graphically on the touch screen in an online format—such as reaction temperature, pressure, time, and stirring speed—allowing users to easily review and analyze the data at any time and export it via USB drive. The system can generate temperature, pressure, and speed curves, and supports unattended operation.

High‑pressure hydrogen generator

The YZHG-500 / YZHG-500H pure water–based high‑purity hydrogen generator employs transition metal element catalysis in its electrolytic cell and undergoes multi‑stage purification, with a built‑in trace oxygen scavenger (which requires no activation), resulting in high‑purity hydrogen gas.

CO2 Adsorption Visual Reactor

The CO2 adsorption visual reactor employs oven heating, a gas buffer tank, and a jacketed reactor design, equipped with high‑temperature oil heating for rapid temperature rise. All valves and pressure sensors are located outside the oven and are fitted with heated piping. The reactor body is equipped with a strip-shaped viewing window, whose flange is engraved with scale markings and allows light to pass through. It is outfitted with high‑precision pressure sensors to accurately monitor and record changes in carbon dioxide pressure within both the gas buffer tank and the reactor. Stirring is performed using an imported, high‑temperature–resistant magnetic stirrer.

Intelligent High-Pressure Reactor

The pilot-scale intelligent reactor manufactured by Shanghai Yanzheng Company integrates the advantages of high‑temperature, high‑pressure reactors with automation and intelligent technologies. With a capacity ranging from 500 ml to 5000 ml, it features a touch screen that offers simple, intuitive, and straightforward operation, along with a clear user interface—solving the mechanical and cumbersome issues associated with traditional button‑based controls. It can record and collect all real‑time data, displaying it graphically on the touch screen in an online format, including reaction temperature, pressure, time, and stirring speed. Users can easily view and analyze this data at any time and export it via USB drive. The system can generate temperature, pressure, and rotational speed curves, and it supports unattended operation.

Acetylene Hydrogenation to Formaldehyde Coupled with Methanol Liquid-Phase Oxidation to Formaldehyde: Batch Reactor Experimental Setup

The acetylene hydrogenation to formaldehyde coupled with methanol liquid-phase oxidation to formaldehyde batch reactor experimental setup allows for homogeneous, long‑cycle batch reactions under medium–high pressure and at relatively low laboratory temperatures. After the long‑cycle reaction, the liquid-phase products can be quantitatively collected from the bottom of the reactor. The system’s operating control is implemented via PLC and a touch‑screen computer. Customized, non‑standard modifications can also be carried out according to different user requirements. This setup is a highly practical long‑cycle catalyst evaluation device for universities and research institutions, boasting excellent practicality.

Autoclave

The PTFE hydrothermal reactor manufactured by Shanghai Yanzheng consists of a high‑quality 304 stainless steel outer vessel with a PTFE inner liner. Its safe operating temperature is below 220°C, and its maximum pressure rating is 3–6 MPa. Featuring an aesthetically pleasing design, a rational structure, simple operation, and excellent corrosion resistance, it is an ideal product for sample digestion in research fields such as university laboratories, environmental monitoring, public health and disease prevention, and quality control.

Microscopic Reaction Kettle

The micro-scale reaction vessel is equipped with strip-shaped viewing windows on adjacent sides and a circular viewing window on the top, featuring a high‑definition camera that can capture real‑time images of the reaction. This ensures the personal safety of laboratory personnel. The reaction vessel comes with software that allows the camera’s recorded video to be displayed directly on a computer screen, automatically generating video files that are saved on the computer—and the videos can be easily exported.

Polymerization Reactor

In modern industrial production, the synthesis of polymeric materials is of paramount importance. Our polymerization reactors, through precise control of reaction conditions, can facilitate the synthesis of a wide variety of polymeric materials, not only enhancing production efficiency but also reducing energy consumption and waste emissions. Polymerization reactors are primarily used in the production of plastics and rubber, playing a crucial role in the development and research of polymeric material applications. Their outstanding performance and reliable quality have earned widespread recognition and high praise from users.
