Great Wall GFY-10L Borosilicate Glass Separatory Funnel Reactor

Overview

The Great Wall GFY-10L Borosilicate Glass Separatory Funnel Reactor is a purpose-engineered laboratory-scale reaction system designed for controlled liquid–liquid phase separation, solvent extraction, and small-batch synthesis under vacuum or inert atmosphere. Unlike conventional separatory funnels, the GFY-10L integrates a sealed, jacketed glass vessel with integrated mechanical stirring, standardized ground-glass interfaces, and vacuum-rated construction—enabling reproducible, operator-safe handling of volatile, moisture-sensitive, or thermally labile reagents. Its core architecture follows the Couette flow principle in stirred batch operation, where the impeller-driven fluid motion ensures uniform mixing while preserving interfacial integrity during settling phases. The reactor operates within a rigorously defined pressure envelope (−0.1 MPa to ambient), supporting applications ranging from acid–base extractions and catalyst recovery to multi-step purification workflows compliant with GLP-aligned laboratory practices.

Key Features

• Borosilicate glass 3.3 body (DIN ISO 3585 compliant) offering exceptional thermal shock resistance (ΔT ≥ 160 °C), chemical inertness against organic solvents, strong acids (e.g., HCl, HNO₃), and alkalis up to 10 mol/L NaOH at room temperature.
• Stainless steel 304 support frame with adjustable height and vibration-damping feet, ensuring mechanical stability during high-speed agitation (up to 500 rpm) and long-duration vacuum operations.
• Integrated frequency-controlled DC motor (90 W) delivering precise, stepless speed regulation between 50 and 500 rpm—optimized for both gentle phase coalescence and vigorous emulsification without cavitation.
• Dual 34/35 standard taper ground joints for modular integration of addition funnels, reflux condensers, or inert gas inlets; one 50# DIN flange port accommodates PTFE-coated stirrer shafts with magnetic or mechanical coupling options.
• Vacuum-rated sealing system validated to maintain −0.1 MPa (≤10 mbar abs) for ≥12 h with no measurable leakage—certified per ASTM E2500-13 Annex A3 for equipment qualification in regulated environments.

Sample Compatibility & Compliance

The GFY-10L is compatible with aqueous, polar aprotic (e.g., DMF, DMSO), and nonpolar organic media (hexane, toluene, chloroform), as well as low-concentration hydrogen peroxide (85 wt%), or supercritical CO₂. All glass components meet ISO 17799:2000 for dimensional tolerance and surface finish. The system supports IQ/OQ documentation packages aligned with FDA 21 CFR Part 11 requirements for electronic records and signatures when paired with validated data acquisition modules.

Software & Data Management

While the base GFY-10L operates as a manually supervised unit, optional digital retrofit kits enable RS-485 Modbus RTU connectivity to third-party SCADA or LIMS platforms (e.g., LabWare, Thermo Fisher SampleManager). Real-time logging of stirrer RPM, elapsed time, and vacuum setpoint (via external Pirani gauge interface) is supported. Audit trails comply with ALCOA+ principles—attributable, legible, contemporaneous, original, accurate, complete, consistent, enduring, and available—when configured with timestamped event recording and user-access controls.

Applications

• Multi-stage solvent extraction of natural product isolates (e.g., alkaloids from plant matrices using CHCl₃–NH₄OH partitioning).
• In-process monitoring of esterification kinetics via periodic sampling through side-arm ports under nitrogen blanket.
• Recovery and recycling of palladium catalysts from Suzuki coupling filtrates using controlled pH-shift precipitation.
• Preparative-scale chiral resolution via diastereomeric salt formation and selective crystallization under reduced pressure.
• Teaching laboratories: Demonstrating partition coefficients (log P), density-driven phase inversion, and mass transfer limitations in immiscible systems.

FAQ

Can the GFY-10L be used for exothermic reactions requiring cooling?
Yes—its double-jacketed borosilicate glass vessel accepts circulating coolant (e.g., ethylene glycol/water mixtures) at temperatures down to −80 °C when connected to an external chiller with ≥1.5 bar delivery pressure.
Is the stirring system explosion-proof?
The standard 90 W motor is not ATEX-certified; however, intrinsically safe (IS) motor variants with IECEx/ATEX Zone 2 rating are available upon request with lead-time extension.
What calibration documentation is provided?
Each unit ships with a Factory Calibration Certificate traceable to NIST standards for vacuum transducer linearity (±0.5% FS) and rotational speed accuracy (±2 rpm at 300 rpm).
How is cleaning validated for GMP pilot runs?
Residue limits (e.g., ≤10 ppm API carryover) can be verified using swab testing per USP and TOC analysis—glass surface area and port geometry are fully accessible for visual inspection and rinse sampling.
