Nanjing Hjchem Offers Compact Benchtop High Pressure Reactors for Laboratory Research and Process Development

Nanjing, China, June 25, 2026 - Nanjing Hjchem Equipment Co., Ltd., a China-based manufacturer of laboratory and pilot process equipment, is offering compact benchtop high pressure reactors for research laboratories, universities, catalyst developers, material science teams, and small-scale process development projects. The equipment is designed for laboratories that need controlled pressure, temperature, stirring, and gas handling in a compact benchtop format.

The benchtop high pressure reactor can be used for high pressure chemical synthesis, hydrogenation studies, catalyst screening, hydrothermal synthesis, polymerization research, material development, corrosion testing, and other small-scale pressure reaction processes. Compared with larger floor-standing reactor systems, the benchtop design helps save laboratory space while still providing a pressure-rated vessel, heating, agitation, pressure monitoring, temperature measurement, gas inlet and vent connections, and safety protection devices.

For early-stage research and development, many laboratories need equipment that is compact, flexible, and suitable for repeatable testing. A benchtop high pressure reactor allows researchers to evaluate reaction conditions, compare catalysts, study gas-liquid reactions, collect process data, and optimize reaction parameters before moving to a larger pilot reactor. This makes it useful for feasibility studies, formulation development, material synthesis, and small-batch reaction optimization.

Hjchem's benchtop high pressure reactor platform can be customized according to the user's process requirements. Typical configurations include small-volume stainless steel pressure vessels, magnetic stirring, electric heating, digital temperature control, pressure measurement, gas inlet and exhaust valves, safety relief devices, and optional data recording. Reactor volume, pressure rating, temperature range, vessel material, stirring method, port arrangement, and control system can be adjusted based on the reaction media and operating conditions.

Available laboratory-scale volumes commonly include 10 mL, 25 mL, 50 mL, 100 mL, 250 mL, 500 mL, and 1000 mL. Standard materials include stainless steel 316L, while special materials or liners may be considered for corrosive media. Depending on the application, optional features may include high pressure feeding, isobaric feeding, internal cooling coil, condenser, gas mass flow control, sampling valve, customized electrodes for electrochemical work, and PLC or touch-screen control.

For many laboratories, the challenge is not only pressure and temperature, but also repeatability, safety, and usable process data. Hjchem's benchtop high pressure reactors are intended to help researchers run small-scale pressure reactions with better control while keeping the system compact and practical for laboratory use.

The company also supports customized reactor systems for users who need special pressure ratings, high-temperature operation, special alloy wetted parts, hydrogenation configurations, photocatalytic or electrochemical setups, and lab-to-pilot scale-up support. By discussing the reaction type, working volume, target temperature and pressure, medium composition, stirring requirements, and safety requirements, Hjchem can recommend a suitable configuration for each project.
