Overview
The Zhengxin ZX-YYG High-Pressure Stainless Steel Laboratory Reactor is an engineered pressure vessel designed for controlled chemical synthesis, catalytic studies, hydrothermal reactions, and high-temperature/pressure process development under inert or reactive atmospheres. Based on Couette-type mechanical integrity and static-seal architecture, the reactor operates on a fixed-volume, batch-mode principle, enabling precise regulation of internal thermodynamic conditions—including pressure, temperature, and gas composition—through integrated instrumentation interfaces. Its robust 316L stainless steel construction ensures long-term compatibility with aggressive reagents (e.g., strong acids, halogenated solvents, supercritical CO₂), while the dual-cone metal gasket sealing system delivers leak-tight performance up to 10 MPa at 300 °C. The unit is not a general-purpose container but a purpose-built reaction platform intended for integration into validated laboratory workflows requiring reproducible, auditable process parameters.
Key Features
- Structurally validated pressure containment per GB/T 25973–2010, with finite-element analysis (FEA) verification of stress distribution across flange, body, and closure assembly
- Torque-calibrated bolted flange system with DIN 2526-compliant conical seating surface for repeatable gasket compression and seal integrity
- Standardized 1/4″ NPT and M12×1.5 threaded ports for pressure transducer, thermocouple, gas inlet/outlet, and sampling valve integration
- Optional external heating/cooling jacket (steam, thermal oil, or circulating chiller compatible) supporting ramp-hold profiles via external PID controller
- Modular accessory support: magnetic drive stirrer (0–1200 rpm, sealed shaftless coupling), gas mass flow controllers (MFCs), and back-pressure regulators (BPRs)
- Surface finish Ra ≤ 0.8 µm electropolished interior for reduced catalytic residue retention and improved cleanability
Sample Compatibility & Compliance
The ZX-YYG accommodates heterogeneous, homogeneous, and multiphase reaction systems—including solid-catalyzed hydrogenations, hydrothermal crystallizations, supercritical fluid extractions, and acid-digestion protocols. It is routinely deployed in laboratories operating under ISO/IEC 17025-accredited quality frameworks and supports GLP-compliant documentation when paired with calibrated pressure/temperature loggers. While not certified to ASME U-Stamp or PED 2014/68/EU, its design adheres to fundamental safety principles outlined in ASME BPVC Section VIII Div. 1 and incorporates fail-safe elements such as burst disc compatibility (optional retrofit) and overpressure venting pathways. All units undergo hydrostatic testing at 1.5× maximum allowable working pressure (MAWP) prior to shipment.
Software & Data Management
The reactor itself is hardware-only and does not include embedded firmware or proprietary software. However, it is fully interoperable with third-party data acquisition systems (e.g., LabVIEW, MATLAB Data Acquisition Toolbox, or Delta Tau PMAC) via analog 4–20 mA or digital RS-485 outputs from externally mounted sensors. Users implementing 21 CFR Part 11 compliance may integrate the ZX-YYG into validated SCADA environments using FDA-auditable electronic loggers (e.g., Omega OM-DAQPRO-5300 series) that provide time-stamped, password-protected, and audit-trail-enabled records of pressure, temperature, and agitation status.
Applications
- Kinetic studies of Fischer–Tropsch, ammonia synthesis, and CO₂ hydrogenation under industrially relevant P–T conditions
- Hydrothermal synthesis of metal–organic frameworks (MOFs), perovskites, and nanocrystalline oxides
- High-pressure digestion of environmental matrices (soils, sediments, biological tissues) for trace metal analysis (ICP-MS/OES)
- Accelerated stability testing of pharmaceutical intermediates under oxidative or humidified pressurized atmospheres
- Material compatibility screening for nuclear fuel cycle chemistry (e.g., uranyl nitrate solutions in HNO₃/HF media)
- Geological simulation experiments involving carbonate dissolution, clay mineral transformation, and fluid–rock interaction
FAQ
Is the ZX-YYG reactor supplied with pressure and temperature sensors?
No. Sensors are selected and installed by the end user based on application-specific accuracy, response time, and chemical compatibility requirements.
Can the reactor be used for exothermic reactions requiring rapid cooling?
Yes—when equipped with a dual-zone jacket and connected to a recirculating chiller capable of sub-ambient operation (−20 °C to 200 °C), the unit supports controlled quenching down to 5 °C/min.
What certification documentation accompanies each unit?
Each reactor ships with a Material Test Report (MTR) for 316L SS, hydrostatic test report, dimensional inspection record, and GB/T 25973–2010 conformance statement.
Is custom port configuration available?
Yes. Zhengxin offers non-standard flange layouts, additional tapping points, and specialized viewports (sapphire or quartz) under OEM engineering agreement.
Does the reactor meet vacuum service requirements for solvent removal or degassing?
Yes—verified leak rate ≤ 1×10⁻⁹ mbar·L/s with helium mass spectrometry; suitable for high-vacuum drying and inert-gas purging protocols.
