JRY-XZ10 Oil-in-Water Extraction Rotational Oscillator

Overview

The JRY-XZ10 Oil-in-Water Extraction Rotational Oscillator is an engineered solution for standardized liquid–liquid extraction of petroleum hydrocarbons and animal/vegetable oils from aqueous environmental matrices. It operates on the principle of controlled rotational agitation—applying consistent torque and orbital motion to separatory funnels—to facilitate efficient partitioning of target analytes into organic solvents (e.g., CCl₄, C₂HCl₃, or alternative IR-transparent solvents) in compliance with HJ 637–2012, the official Chinese national standard for infrared spectrophotometric analysis of oil content in water. Unlike vortex mixers or reciprocal shakers, this device maintains stable angular momentum across all 10 sample positions simultaneously, minimizing inter-sample variability and ensuring reproducible phase separation kinetics essential for quantitative IR absorbance measurement at 2930 cm⁻¹, 2960 cm⁻¹, and 2870 cm⁻¹. Its rigid mechanical architecture supports high-mass loading (up to 10 × 1000 mL funnels), enabling batch processing without compromising rotational fidelity or thermal equilibrium.

Key Features

• Hermetically sealed extraction chamber with integrated polycarbonate viewing window—eliminates volatile organic compound (VOC) leakage and operator exposure during CCl₄-based extractions.
• High-torque, brushless AC motor delivering stable 0–300 rpm rotation with <±1 rpm speed repeatability over extended duty cycles (≥8 h continuous).
• Programmable timing interface supporting discrete forward/reverse intervals (JRY-XZ-MF variant), enabling optimization of emulsion breakdown for viscous or surfactant-laden wastewater samples.
• Full stainless-steel (AISI 304) enclosure with electropolished finish—resistant to corrosion from halogenated solvents and compatible with laboratory-grade disinfection protocols.
• Interlocked safety shield with microswitch-driven cut-off circuitry—power disengages instantly when shield is lifted, meeting IEC 61010-1 electrical safety requirements.
• Leak containment base featuring recessed drainage grooves and sloped geometry—prevents solvent pooling and facilitates rapid spill cleanup.
• Real-time temperature monitoring with PID-regulated ambient compensation—maintains thermal stability within ±1.5 °C across full load, critical for solvent density consistency and phase separation reproducibility.
• Dedicated universal clamp assembly accommodating 50 mL to 1000 mL glass or PTFE-coated separatory funnels (standardized neck diameters: 24/40, 29/32, 45/50).

Sample Compatibility & Compliance

The JRY-XZ10 is validated for use with standard volumetric separatory funnels compliant with GB/T 12805–2011 (Chinese national standard for laboratory glassware). It supports both single-phase and multi-phase aqueous samples—including turbid surface water, saline groundwater, activated sludge effluent, and oily industrial discharges—as defined in HJ 637–2012 Annex A. Device operation adheres to GLP-aligned documentation practices: all time/speed/temperature parameters are manually logged or exportable via optional RS-232 interface (JRY-XZ-MF). While not intrinsically 21 CFR Part 11 compliant, its mechanical design and traceable operational parameters support audit-ready workflows under ISO/IEC 17025-accredited environmental testing laboratories.

Software & Data Management

The base JRY-XZ10 model features a front-panel digital interface with LED display and tactile membrane keys for direct parameter entry (speed, duration, pause intervals). For enhanced traceability, the optional JRY-XZ-MF configuration includes USB/RS-232 connectivity and companion Windows-based software enabling method storage, run history logging, and CSV-formatted export of timestamped operational records—including start/stop events, speed deviations, and thermal drift alerts. All firmware revisions undergo version-controlled validation per ISO 9001 clause 7.5.2, with calibration certificates available upon request.

Applications

• Regulatory monitoring of petroleum hydrocarbon discharge limits in municipal wastewater treatment plants (WWTPs) per HJ 637–2012 and local environmental protection bureau mandates.
• Pre-extraction conditioning for EPA Method 1664B (n-hexane extractable material) and ASTM D7066–17 (oil and grease by infrared).
• Research-scale extraction of bio-oils from algal cultivation media or fermentation broths.
• Method development for solvent-free or low-solvent alternatives requiring precise agitation kinetics.
• Quality control of industrial cooling water systems where hydrocarbon ingress must be quantified at sub-ppm levels.

FAQ

Is the JRY-XZ10 compatible with non-standard funnel geometries (e.g., pear-shaped or pressure-rated)?
Yes—custom clamping fixtures are available as OEM accessories for specialized glassware, provided neck dimensions and center-of-gravity constraints fall within mechanical stability thresholds (max. 1200 g per funnel at 300 rpm).
Can the unit operate unattended overnight?
Yes—timer settings up to 99 hours support fully automated batch runs; however, solvent compatibility and lab safety protocols must be verified prior to extended operation.
Does the device meet international electromagnetic compatibility (EMC) standards?
It complies with GB/T 18268.1–2010 (equivalent to IEC 61326-1:2012 Class A for laboratory equipment) for conducted/radiated emissions and electrostatic discharge immunity.
What maintenance is required for long-term reliability?
Biannual inspection of drive belt tension, bearing lubrication (grease type: NLGI #2 lithium complex), and verification of interlock switch functionality is recommended; no routine motor servicing is needed due to brushless design.
Is third-party calibration certification available?
Yes—NIST-traceable speed and temperature calibration reports (per ISO/IEC 17025) can be issued by authorized service centers upon request.
