Zhengxin PS-200ML Explosion-Proof Laboratory Reactor

Overview

The Zhengxin PS-200ML Explosion-Proof Laboratory Reactor is an engineered pressure vessel designed for safe, controlled chemical synthesis and catalytic reaction studies under elevated temperature and pressure conditions. It operates on the principle of sealed batch reaction dynamics, where reactants are confined within a hermetically sealed, mechanically robust chamber while subjected to precisely regulated thermal and gaseous environments. Its explosion-proof architecture conforms to national safety standards for laboratory-scale pressurized systems (GB/T 150.1–2011), incorporating dual-layer mechanical overpressure protection—comprising a calibrated rupture disc and spring-loaded relief valve—to prevent catastrophic failure during exothermic or gas-evolving reactions. The reactor supports inert atmosphere purging, vacuum degassing, and controlled gas dosing, making it suitable for hydrogenation, oxidation, polymerization, hydrothermal synthesis, and solvent-free catalysis workflows in academic research labs and QC/QA facilities.

Key Features

• Pressure-rated stainless steel 304 body (optional 316L, Hastelloy C-276, titanium, or zirconium) with mirror-polished internal surface (Ra ≤ 0.4 µm) for corrosion resistance and easy cleaning
• Full-range pressure tolerance from –0.1 MPa (vacuum) to +6 MPa (gauge), validated per ASME Section VIII Div. 1 equivalent design criteria
• LCD-based PID temperature controller with real-time setpoint programming, auto-tuning, and ±1 °C steady-state accuracy across 0–400 °C operating range
• Modular gas handling interface: dual 1/8″ and 1/4″ VCR-compatible needle valves for high-purity gas introduction and venting; compatible with mass flow controllers and gas chromatography sampling lines
• Integrated safety system including certified rupture disc (set point adjustable between 4–6 MPa), redundant mechanical relief valve, and visual pressure indication via calibrated analog gauge (optional digital transducer)
• Thermal management flexibility: supports external oil bath, sand bath, or water bath immersion; optional finned aluminum heat sink for passive cooling during post-reaction quenching
• Configurable internal lining options—including fused quartz, PTFE-coated stainless steel, or custom metallurgical liners—for aggressive media compatibility (e.g., HF, molten alkalis, chlorine-rich environments)

Sample Compatibility & Compliance

The PS-200ML accommodates heterogeneous and homogeneous reaction mixtures up to 200 mL working volume, with recommended fill ratio of 50–70% to ensure adequate headspace for vapor expansion and agitation safety. It is routinely employed in ASTM E2892-compliant reaction calorimetry trials, ISO 11225 hydrothermal stability testing, and USP catalytic activity assessments. All wetted components meet FDA 21 CFR Part 11 traceability requirements when paired with validated data logging software. The reactor’s construction documentation includes material test reports (MTRs), non-destructive examination (NDE) records, and pressure test certificates—supporting GLP/GMP audit readiness and institutional safety office certification.

Software & Data Management

While the base unit operates via standalone PID hardware, optional RS485/Modbus RTU or USB-C interface enables integration with third-party SCADA platforms (e.g., LabVIEW, MATLAB, DeltaV). When configured with the Zhengxin DataBridge Module, users gain timestamped, encrypted logging of temperature, pressure, and heating power at 1 Hz resolution—with automatic CSV export, alarm event tagging, and electronic signature support aligned with 21 CFR Part 11 Annex 11 requirements. Audit trails include operator ID, parameter change history, and calibration certificate linkage.

Applications

• Catalytic hydrogenation of unsaturated organic compounds under H₂ (up to 4 MPa)
• Hydrothermal synthesis of metal–organic frameworks (MOFs) and nanocrystalline oxides
• High-boiling-point solvent reactions (e.g., DMF, NMP, sulfolane) requiring reflux suppression
• Corrosion-resistant testing of battery electrolyte formulations at elevated T/P
• Photochemical reactions using quartz-lined variants with UV-transparent windows
• Green chemistry process development: solvent-free esterification, transesterification, and amidation

FAQ

What certifications does this reactor carry for international laboratory use?
It complies with GB/T 150.1–2011 (Chinese pressure vessel standard), and optional CE marking can be provided upon request with EU Notified Body assessment.
Can the reactor be used under vacuum prior to gas introduction?
Yes—it achieves –0.1 MPa absolute vacuum and includes dedicated purge/evacuate cycles via the dual needle-valve manifold.
Is remote monitoring supported out of the box?
No—remote capability requires the optional DataBridge Module and compatible host software; basic operation is fully manual/local.
What is the maximum allowable fill volume for safe operation at 400 °C?
At full temperature rating, the recommended maximum liquid fill is 140 mL (70% of 200 mL capacity) to accommodate thermal expansion and vapor phase equilibrium.
Are replacement rupture discs available as consumables?
Yes—Zhengxin supplies certified, lot-traceable rupture discs calibrated for 4.5 MPa, 5.0 MPa, and 5.5 MPa set points, with recalibration service available every 12 months.
