The SOX406 is a Soxhlet-style fat analyzer designed to determine fat (lipid) content in foods, animal feeds, medicines and other solid or semi-solid samples (also suitable for soils, polymers, textiles, etc.). It integrates soaking, extraction, heating, condensation and solvent recovery in one unit.
Sample weights between 0.5 g and 15 g can be analyzed (2–5 g is typical for accurate results). The unit processes up to 6 samples per batch.
Temperature is adjustable from room temperature +5°C up to 280°C. Built-in PID control provides temperature accuracy of ±1°C.
Common Soxhlet solvents such as petroleum ether, hexane and ether may be used—choose solvent appropriate for your method and safety rules. Each solvent cup has an 80 mL volume. Always follow solvent compatibility and safety guidance.
The SOX406 has a high solvent recovery rate of ≥80%, which reduces solvent consumption and operating cost. Actual recovery depends on solvent type and operating conditions.
Extraction time depends on sample matrix, solvent and method parameters. The design can shorten extraction time by approximately 20%–80% compared with some conventional procedures, depending on conditions.
Safety features include complete isolation between electrical circuits and extraction space, air-insulation to keep the cabinet near room temperature, over-temperature alarm and timer reminders. The unit provides triple alarms (sound, light and LCD text) and has an all-around 360° safety design.
The SOX406 uses a 4.3-inch LCD with microcomputer control. The interface displays set temperature, actual temperature, set time and elapsed heating time simultaneously and supports intelligent man–machine dialogue control.
Measurement range is 0–100% fat. Reproducibility relative error is approximately 1%. Rated power consumption is 1 kW and the unit requires 220 VAC ±10%, 50 Hz.
Regularly clean extraction glassware (thimbles, condensers, solvent cups), check and replace seals/gaskets if worn, inspect electrical connections and the heating bath for corrosion, and ensure vents are clear. Follow solvent-specific cleaning procedures and drain/dispose solvent residues per local regulations.
Validate using certified reference materials or standard test samples and follow your laboratory's method validation procedures (precision, accuracy, recovery). Periodically verify temperature accuracy and timing and run control samples to monitor performance.
The SOX406 is based on the Soxhlet extraction principle and can be used to perform Soxhlet-based methods. To ensure compliance, set method parameters (sample weight, solvent, extraction time, temperature) according to the specific AOAC/ISO standard you follow.
Keep spare solvent cups (80 mL), extraction thimbles, seals/gaskets, condensers, tubing, and common replacement fuses or sensors. Maintain appropriate quantities of your chosen solvent and personal protective equipment.
Collect and store used solvents in appropriate, labeled containers and dispose of or recycle them according to local hazardous-waste regulations. Use proper ventilation, grounding and explosion-proof equipment when handling flammable solvents.
SOX606 is listed as a related model; differences typically include capacity, feature set or performance improvements. For exact comparisons (batch size, power, dimensions, advanced features), refer to the technical datasheets for each model or consult the manufacturer/supplier.
