JRY-F8/F10 Vertical Oscillating Liquid-Liquid Extractor

Overview

The JRY-F8/F10 Vertical Oscillating Liquid-Liquid Extractor is an engineered laboratory platform designed for reproducible, high-throughput liquid-liquid extraction (LLE) in environmental, food safety, pharmaceutical, and analytical chemistry laboratories. It operates on the principle of controlled vertical oscillation—applying precise, repeatable mechanical motion to standard glass or PTFE-lined separatory funnels—to facilitate phase separation, mass transfer, and efficient analyte partitioning between immiscible solvents. Unlike rotary shakers or horizontal orbital agitators, this system maintains consistent orientation of the funnel during agitation, minimizing emulsion formation and improving interfacial contact kinetics. Its operation is optimized for regulatory-compliant sample preparation workflows requiring adherence to standardized methods such as EPA Method 3510C (liquid-liquid extraction), ISO 17993:2004 (water quality analysis), and USP residual solvent testing protocols.

Key Features

• Vertical oscillation mechanism with infinitely variable speed control (0–300 cycles/min), enabling method-specific optimization for diverse solvent systems (e.g., dichloromethane/water, hexane/acetone, ethyl acetate/buffer).
• Dual-mode operation: programmable timed extraction (1–120 min) and continuous oscillation mode, supporting both routine QC and method development applications.
• Low-acceleration start-up buffer function reduces mechanical stress on glassware, extending funnel service life and minimizing risk of leakage or breakage during high-volume batch processing.
• Ultra-quiet DC motor drive system (<55 dB(A) at 1 m distance), suitable for shared laboratory environments where acoustic interference must be minimized.
• Modular sample platform accommodates 8, 10, 12, or 16 standard separatory funnels (up to 1000 mL capacity each), with universal clamping fixtures compatible with conical, pear-shaped, and cylindrical funnel geometries.
• Thermostatically stabilized chamber (0–25 °C operating range) supports temperature-sensitive extractions, including volatile organic compound (VOC) recovery and thermolabile pesticide isolation.

Sample Compatibility & Compliance

The JRY-F8/F10 is validated for use with common LLE-compatible materials—including borosilicate glass, PTFE-coated stopcocks, and chemically resistant rubber gaskets—and complies with general laboratory safety standards for pressure-rated equipment (max. 0.1 MPa). While not classified as a pressurized reaction vessel, its sealed-funnel configuration meets containment requirements for low-volatility solvent handling under ambient conditions. The system supports GLP/GMP-aligned documentation practices through manual logbook integration and is compatible with audit-ready SOPs referencing ASTM D3720 (oil-in-water extraction), ISO 11337 (pesticide residue analysis), and EU Directive 2009/128/EC (integrated pest management sampling protocols).

Software & Data Management

This model operates via front-panel digital interface with LED display; no embedded software or network connectivity is included. All operational parameters—including oscillation frequency, duration, and start/stop status—are manually set and visually confirmed. For laboratories requiring electronic recordkeeping, the device integrates seamlessly with external LIMS or ELN platforms via time-stamped operator logs and standardized parameter templates. Optional external data acquisition modules (e.g., USB-connected timer/logger units) may be deployed to generate 21 CFR Part 11–compliant audit trails when used in regulated environments.

Applications

• Environmental monitoring: extraction of PAHs, PCBs, organochlorine pesticides, and phenolic compounds from aqueous matrices (surface water, wastewater, leachates).
• Food and agricultural testing: determination of veterinary drug residues, mycotoxins, and lipid-soluble contaminants in milk, meat, and plant tissues.
• Clinical and forensic toxicology: isolation of drugs of abuse (e.g., benzodiazepines, opioids) from biological fluids prior to GC-MS or LC-MS/MS analysis.
• Pharmaceutical R&D: purification of active pharmaceutical ingredients (APIs) from reaction mixtures and removal of residual solvents per ICH Q3C guidelines.
• Soil and solid waste characterization: sequential extraction of heavy metals (e.g., Pb, Cd, Cr) using acid–solvent biphasic systems under controlled temperature.

FAQ

What types of separatory funnels are compatible with the JRY-F8/F10?
Standard glass separatory funnels ranging from 125 mL to 1000 mL capacity, including those with PTFE stopcocks and reinforced necks, are fully supported. Funnel diameters up to 120 mm are accommodated by the adjustable clamp assembly.
Can the unit operate unattended for extended periods?
Yes—when configured in timed mode with verified seal integrity and appropriate solvent compatibility, the system supports unattended operation for up to 120 minutes. Routine visual inspection before initiation is recommended for safety compliance.
Is temperature control integrated into the oscillation chamber?
The unit includes ambient temperature stabilization within 0–25 °C but does not feature active refrigeration or heating. External cold rooms or incubator cabinets may be used for sub-ambient or elevated temperature extractions.
How is maintenance performed on the DC motor and drive mechanism?
The brushless DC motor requires no scheduled lubrication. Annual inspection of belt tension (if applicable), mounting hardware torque, and clamp spring integrity is advised per manufacturer’s preventive maintenance checklist.
Does the system meet any international electrical safety certifications?
The JRY-F8/F10 conforms to GB 4793.1–2019 (Chinese equivalent of IEC 61010-1) for electrical safety in laboratory equipment. CE marking is not applied; users deploying the instrument outside China should verify local regulatory acceptance prior to installation.
