Apparatus and Equipment

The Digital Soxhlet Extractor is comprised of high-quality components that ensure reliable performance and durability. It includes a heating unit with multiple hot plate-type heaters, a condenser assembly, and a collection flask. The apparatus is equipped with digital controls and displays, allowing for precise temperature and time settings. The Soxhlet extraction method involves the repeated cycle of solvent extraction and reflux, facilitated by the efficient design of the apparatus.


  • Heating Unit: The apparatus features a heating unit with multiple hot plate-type heaters, providing uniform and controlled heating.
  • Condenser Assembly: The condenser assembly efficiently cools and condenses the solvent vapors, preventing their escape into the laboratory environment.
  • Collection Flask: A collection flask is provided to collect the extracted fat or oil for further analysis.
  • Digital Controls: The digital controls enable precise temperature and time settings, ensuring accuracy and reproducibility.
  • Safety Features: The apparatus incorporates safety features such as overheating protection and a built-in safety circuit.


  1. Prepare the sample: Grind or finely chop the sample to increase the surface area for extraction.
  2. Weigh the sample: Accurately weigh the sample and place it in a filter paper.
  3. Assembly: Set up the Soxhlet extraction apparatus by connecting the condenser, collection flask, and sample holder.
  4. Solvent selection: Choose an appropriate solvent for the extraction process, considering the solubility of fat or oil in the selected solvent.
  5. Start the extraction: Fill the extraction flask with the selected solvent, set the desired extraction temperature and time on the digital control panel, and initiate the extraction process.
  6. Reflux and extraction: The solvent vapor rises, condenses in the condenser, and drips back onto the sample, facilitating the extraction of fat or oil.
  7. Collection: The extracted fat or oil accumulates in the collection flask.
  8. Analysis: Once the extraction is complete, the collected fat or oil can be further analyzed using suitable analytical techniques.
