Overview
The BenAng SXT-06 Six-Channel Soxhlet Extractor is an engineered laboratory instrument designed for quantitative fat and lipid extraction using the classical Soxhlet principle—continuous solvent reflux and cyclic percolation through solid samples. It operates on the fundamental thermodynamic and mass-transfer principles of solid-liquid extraction, where a boiling solvent repeatedly condenses, drips onto the sample in the thimble, dissolves analytes (e.g., triglycerides, waxes, or non-polar compounds), and returns to the boiling flask via siphon action. This closed-loop thermal cycling ensures high extraction efficiency and reproducibility across multiple samples simultaneously. The SXT-06 complies with internationally recognized methodologies including AOAC Official Method 920.39, ISO 6496:1999, and GB/T 5512–2018 (replacing GB 5512-85), making it suitable for routine quality control and regulatory-compliant analysis in food, feed, oilseed, and agricultural laboratories.
Key Features
- Six independent extraction channels enable parallel processing of up to six samples (0–5 g each), significantly improving throughput without cross-contamination.
- Integrated solvent recovery system automatically condenses and returns vaporized solvent to the reservoir, minimizing reagent consumption and reducing exposure risk.
- Precise digital temperature control (±1°C) across a broad operational range (ambient +5°C to 100°C), compatible with common solvents including petroleum ether (bp ~40–60°C), diethyl ether (bp 34.6°C), and hexane (bp 69°C).
- Modular architecture separates heating, extraction, and condensation zones—enhancing thermal stability and simplifying maintenance.
- Programmable extraction timer with audible end-of-cycle alarm supports method standardization and unattended operation.
- Robust stainless-steel housing and borosilicate glass components ensure chemical resistance and long-term durability under repeated thermal cycling.
Sample Compatibility & Compliance
The SXT-06 accommodates solid and semi-solid matrices with fat content ranging from 0.5% to 60%, including cereal grains, oilseeds (soybean, rapeseed), animal feed, dried dairy products, and processed foods. Each channel accepts standard 25–35 mm diameter cellulose or glass-fiber thimbles. The system meets GLP-aligned operational requirements: all temperature setpoints and run durations are manually logged, and the heater’s stable thermal profile supports method validation per ISO/IEC 17025. While not inherently 21 CFR Part 11 compliant (lacking electronic audit trail), its mechanical design and consistent performance support manual data integrity practices required under FDA-regulated environments when integrated into validated SOPs.
Software & Data Management
The SXT-06 is a standalone benchtop instrument with no embedded software or connectivity interfaces. All operational parameters—including heating setpoint, timer duration, and channel activation—are configured via front-panel digital controls. Users maintain traceability through manual logbooks or LIMS-integrated entry of batch ID, sample weight, solvent type, extraction time, and final extract mass. For laboratories requiring digital workflows, the device is fully compatible with external balance integration (via RS-232 or USB-serial adapters) and can be incorporated into automated reporting templates aligned with ISO 17025 documentation standards.
Applications
- Routine crude fat determination in cereal and legume samples per AOAC 920.39 and ISO 6496.
- Quality assurance testing of commercial animal feed formulations for lipid consistency.
- Raw material screening in edible oil refineries to verify oilseed oil yield prior to pressing or solvent extraction.
- Research-scale isolation of lipophilic phytochemicals (e.g., carotenoids, tocopherols) from plant tissues.
- Validation of alternative extraction methods (e.g., ASE, ultrasonic) by benchmarking against classical Soxhlet recovery rates.
FAQ
What solvents are compatible with the SXT-06?
Petroleum ether (40–60°C fraction), n-hexane, diethyl ether, and chloroform are commonly used. Solvent selection must consider boiling point compatibility with the 100°C maximum heating limit and safety protocols for flammability and toxicity.
Is the SXT-06 suitable for volatile or heat-sensitive analytes?
No—it relies on continuous reflux at or near solvent boiling point; therefore, it is not recommended for thermolabile compounds. For such applications, consider low-temperature techniques like cold maceration or pressurized liquid extraction.
Can I use custom-sized thimbles or flasks?
The unit is calibrated for standard 25–35 mm thimbles and 150 mL receiver flasks. Deviations may affect siphon timing, solvent volume management, and extraction efficiency—and are not supported under warranty.
Does the instrument include calibration certification?
Factory calibration of the temperature sensor is performed pre-shipment. A certificate of conformance is provided; however, accredited temperature calibration (e.g., NIST-traceable) requires third-party service.
How often should the condenser cooling water tubing be inspected?
Inspect before each use for kinks, cracks, or biofilm buildup. Replace silicone tubing every 6–12 months depending on water quality and usage frequency to prevent flow restriction and overheating.
