Automatic Soxhlet Extractor - Efficient Fat Analysis System

The automatic Soxhlet extractor is based on the classic Soxhlet extraction principle, and achieves efficient, safe, and accurate fat extraction through automated temperature control, solvent recovery, and integrated design, becoming an important analytical tool in modern laboratories.

The importance of automatic Soxhlet extractor

Fat content is a core indicator for food nutrition labeling, agricultural product quality grading, and quality control of pharmaceutical excipients. The importance of an automatic Soxhlet extractor is reflected in:

Improve detection efficiency: Shorten the traditional manual extraction time of 8-24 hours to 2-4 hours, and batch process 6 samples.

Ensure data accuracy: Relative standard deviation ≤ ± 1% (5-100% fat range), meeting the requirements of standard methods.

Reduce safety risks: Fully enclosed system and automatic solvent recovery (recovery rate ≥ 85%) to reduce exposure to toxic solvents.

Cost saving: Reduce solvent usage by more than 50% and lower waste liquid treatment costs.

Technical principles

The automatic Soxhlet extractor is based on the Soxhlet extraction principle, and its core workflow includes:

Hot soaking stage: The sample is soaked in a heated solvent, and the fat is initially dissolved.

Extraction cycle: solvent evaporation → condensation reflux → sample rinsing → fat enrichment → solvent recovery, repeated multiple times.

Solvent recovery: After extraction, the solvent is automatically distilled to reduce waste and pollution.

Drying and weighing: Dry the residue directly and calculate the fat content.

The instrument is equipped with a well type electric heating module (adjustable from room temperature to 200 ℃) and a PTFE sealing system to ensure precise temperature and safe operation.

Technical advantages

The automatic Soxhlet extractor integrates precision temperature control, automation, and safety design:

Precision temperature control system: Six stage programmed heating (temperature and time can be set for each stage), adapted to different sample characteristics; The temperature control accuracy is ± 0.2 ℃ to avoid the decrease in extraction efficiency caused by solvent boiling point fluctuations.

Intelligent operation: 2.5-inch color LCD screen, real-time display of set temperature, actual temperature, and insulation countdown; One click start of multi-stage program without manual intervention.

Safety and Environmental Protection: Non plug condenser tube design to avoid glass wear and solvent leakage; Automatic solvent recovery function, with a recovery rate of ≥ 85%, reducing environmental pollution.

Durability and compatibility: The electrolytic mirror stainless steel body is corrosion-resistant and easy to clean; Supports sample sizes of 0.5-15g, covering common testing needs.

Application Fields

The automatic Soxhlet extractor is widely used in the following scenarios:

Food industry: Fat content testing for meat, dairy products, edible oils, nuts, etc.

Agricultural Product Processing: Quality Analysis and Trade Grading of Grain and Oil Crops.

Environmental monitoring: determination of oil and fat content in soil and sludge.

Drugs and cosmetics: Extraction of fat soluble components from excipients and raw materials.

Research and Education: Used by universities and research institutes for teaching and research in nutrition and chemical analysis.

The automatic Soxhlet extractor solves the pain points of efficiency, safety, and consistency in traditional fat extraction methods through automation, precise temperature control, and safety design. Its efficient, reliable, and environmentally friendly characteristics make it an important tool in the fields of food, environmental, and drug testing. With the increasing demand for laboratory automation, automatic Soxhlet extractors will further develop towards intelligence and high-throughput, providing stronger technical support for quality control and scientific research.
