The SOX406 Fat Analyzer Soxhlet Extractor is designed to accurately measure fat content in various samples. Ideal for use in food, feed, and medicine industries, this reliable equipment is simple to operate and provides precise results. With its adjustable temperature range and high solvent recovery rate, it ensures efficient extraction and analysis.
The SOX406 Fat Analyzer Soxhlet Extractor is an essential tool for anyone needing accurate fat content analysis in various materials. Its high precision and efficiency make it a top choice for labs and production facilities.

Introduction:
SOX406 Fat Analyzer is based on the Soxhlet extraction principle and integrates such functions as soaking, extraction, leaching, heating, condensation, and solvent recovery. It features sealed metal bath heating with automatic temperature control, ensuring uniform heating and safe operation; six samples can be tested at the same time, and optimal temperature can be selected according to the difference between reagent boiling point and ambient temperature to achieve quick analysis; reagents can also be recycled to reduce test cost; and soaking, extraction and solvent recovery can be done in one step. Therefore, this device is characterized by reasonable design, stable performance, good reproducibility, high accuracy, easy operation, saving time and effort, and so on.
Feature
1. Integral metal heating, while the scope and high precision of temperature control
2. The electric circuit is isolated from the extraction space, ensuring devices security
3. Over-temperature alarming and timer reminding functions are available
4. The timer circuit is isolated from the extraction space, ensuring device security
5. Triple alarms i.e. sound, light, LCD screen word prompts are available
6. Abundant interface contents give simultaneous display of given temperature, actual temperature, given time, and heating time
7. The lifting connection of linear bearing conduction technique gives smooth and comfortable lifting operation
8. Intelligent man-machine dialogue control system
9. Exclusive air insulation technique leaves the case in room temperature, has thermal insulation and temperature maintenance two functions
10. 4.3" LCD screen and microcomputer control system are adopted
- 360 degree all-round safety design
The instrument adopts the design of complete isolation between the circuit and the extraction space, and the air insulation
technology effectively improves the thermal insulation characteristics of the machine, to keep the equipment shell at room
temperature. Built-in multiple warning function, in case of over-temperature, timeout, etc., it can give an alarm by means of
sound, light signal and screen display.
- Integral metal heating
The instrument adopts automatic temperature control and fully sealed metal bath heating method, and can test 6 samples at the same time. The intelligent man-machine dialogue control system can display the set temperature, actual temperature, set time and
heating time synchronously through rich interface content. The optimal temperature can be selected according to the difference of the boiling point of the reagent and the natural temperature, so as to achieve the purpose of rapid determination.
- Durable design concept
SOX406 Soxhlet extractor has precise timing reminder function. The specially equipped alarm system will remind users through multiple alarm systems such as voice and LCD text prompts when over temperature occurs. The whole machine adopts unique anti-corrosion technology to effectively avoid the influence of the environment on the machine. The integrated metal bath heating module makes the temperature control range wider and effectively prolongs the life of the heating plate. The built-in professional PID temperature control system can make the temperature control accuracy less than 1℃.

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.
