Hanon SOX606 Soxhlet Extractor (Fat Analyzer)

Overview

The Hanon SOX606 Soxhlet Extractor is a precision laboratory instrument engineered for quantitative fat and lipid extraction based on the classical Soxhlet principle—continuous solvent reflux and cyclic percolation through solid samples. It operates by repeatedly washing ground or homogenized samples with boiling organic solvent (e.g., petroleum ether, diethyl ether, hexane, chloroform, or acetone), followed by condensation and return of solvent to the extraction thimble. This thermally driven, closed-loop extraction process ensures high recovery efficiency of non-polar and moderately polar lipids while minimizing operator intervention. Designed for compliance with international gravimetric and volumetric fat determination protocols, the SOX606 supports method flexibility across regulatory frameworks including AOAC Official Methods, ISO 6496, ISO 1444, and ASTM D7213—all of which reference Soxhlet-based procedures for fat quantification in food, feed, environmental matrices, and pharmaceutical excipients.

Key Features

• Five programmable extraction modes: Standard Soxhlet (ISO/GB-compliant), Hot Soxhlet, Hot Extraction (non-cyclic), Continuous Flow Extraction, and CH-Standard Hot Extraction—enabling method optimization for diverse sample matrices and solvents.
• Integrated embedded metal heating system with rapid thermal response, uniform temperature distribution, and energy-efficient operation (rated power: 2.0 kW).
• Six independent extraction channels with all-wetted parts constructed from borosilicate glass and PTFE—ensuring chemical inertness, minimal contamination risk, and compatibility with aggressive solvents (aromatics, ethers, ketones, halogenated hydrocarbons).
• Wall-mounted vertical touchscreen controller featuring Android-style UI—intuitive navigation, preloaded solvent profiles, one-touch start/pause, real-time status feedback, and customizable method templates.
• Comprehensive safety architecture: integrated ether vapor leakage detection with audible/visual alarm, cold water inlet/outlet temperature and flow monitoring, real-time condensate level sensing, and automatic shutdown upon anomaly detection (dry-heating, coolant failure, overtemperature).
• High-efficiency solvent recovery system achieving ≥85% recovery rate—reducing reagent consumption, disposal costs, and environmental impact.

Sample Compatibility & Compliance

The SOX606 accommodates solid and semi-solid samples ranging from 0.5 g to 15 g per thimble, including but not limited to cereal grains, meat products, dairy powders, oilseeds, animal feed, soil, sludge, activated carbon, and pharmaceutical tablets. Its design conforms to GB 5009.6–2016 (China’s National Food Safety Standard for Fat Determination), GB/T 9695.1–2008 (Meat and Meat Products – Free Fat), GB/T 6433–2006 (Feed Crude Fat), and GB/T 5512–2008 (Cereals and Oilseeds – Crude Fat). The instrument supports GLP-aligned workflows through audit-trail-capable method logging, user access control (via controller login), and timestamped run records—facilitating traceability during internal QA audits or regulatory inspections under ISO/IEC 17025 or FDA 21 CFR Part 11 requirements.

Software & Data Management

The embedded controller runs a deterministic real-time OS with persistent local storage for ≥10,000 method files and run logs. Each extraction cycle stores metadata including start/stop time, setpoint temperature profile, actual chamber temperature history (sampled at 2-second intervals), solvent type, channel activation status, and any triggered alarms. Data export is supported via USB flash drive in CSV format for downstream analysis in LIMS or statistical software (e.g., JMP, Minitab). No cloud connectivity or remote access is implemented—ensuring data sovereignty and alignment with institutional IT security policies governing analytical instrumentation.

Applications

The SOX606 serves as a primary fat quantification tool in accredited food testing laboratories (e.g., AOAC-certified labs performing routine QC on edible oils, infant formula, or processed meats); agricultural research institutes evaluating oilseed cultivars; environmental labs analyzing total petroleum hydrocarbons (TPH) in contaminated soils per EPA Method 9071A; and pharmaceutical R&D units extracting lipid-based drug carriers or residual solvents from granules. Its broad solvent compatibility also enables applications beyond fat analysis—including alkaloid isolation from plant material, wax extraction from beeswax or crude petroleum, and leaching studies of plasticizers from polymeric packaging.

FAQ

What solvent types are compatible with the SOX606?
All common low-boiling organic solvents are supported—including petroleum ether (bp 40–60°C), diethyl ether (bp 34.6°C), n-hexane (bp 69°C), chloroform (bp 61°C), and acetone (bp 56°C)—provided appropriate ventilation and explosion-proof infrastructure are in place.
Does the SOX606 meet ISO/IEC 17025 documentation requirements?
Yes—each extraction run generates a tamper-evident digital log with method parameters, operator ID, timestamps, and deviation flags, supporting traceability and method validation per ISO/IEC 17025:2017 Clause 7.7.
Can the instrument be validated for GMP environments?
While the SOX606 itself is not 21 CFR Part 11–certified out-of-the-box, its deterministic controller architecture, audit trail capability, and configurable user roles enable qualification (IQ/OQ/PQ) within GMP-compliant facilities when integrated into a documented validation protocol.
What maintenance is required for long-term reliability?
Routine maintenance includes quarterly verification of temperature sensor calibration (using NIST-traceable dry-block calibrator), biannual inspection of PTFE seals and glass joints for wear, and annual cleaning of condenser coils and solvent reservoir filters.
Is method transfer from older Soxhlet systems feasible?
Yes—the SOX606 replicates classical Soxhlet kinetics with enhanced thermal stability and reduced solvent loss; method equivalence studies typically demonstrate <1.5% relative difference in fat recovery versus AOAC 920.39 or ISO 6496 reference methods.
