Soxhlet Extractor

The Soxhlet extractor is a laboratory apparatus used for continuous solvent extraction of solid samples. It operates on the principle of solvent reflux and siphon action, enabling efficient and solvent-saving extraction of compounds from solid matrices. The system consists of a condenser, extraction tube, and extraction flask, all connected via standard taper joints. Available in volumes from 60 ml to 2000 ml, it supports both ball-shaped and snake-shaped condensers for different application needs.

Continuous extraction with minimal solvent use, reducing reagent cost and waste
High extraction efficiency due to repeated solvent reflux and siphon cycles
Standard taper joint compatibility ensures secure, leak-free assembly across all components
Available in multiple sizes (60 ml to 2000 ml) to match sample volume and throughput requirements

Comparison

Compared With The Alternatives

Versus Batch solvent extraction

Soxhlet provides continuous extraction with lower solvent use and higher recovery efficiency, reducing time and material costs

Versus Ultrasonic extraction

Soxhlet offers better reproducibility and higher yield for thermally stable compounds, though it requires longer run times

Versus Soxhlet with non-standard joints

Standard taper joints ensure compatibility and leak resistance, unlike improvised or non-precision fittings

Versus Single-use extraction kits

Soxhlet is reusable and cost-effective for high-volume or repetitive extraction tasks

Use Guide

How To Use It

Assemble components using standard taper joints, ensuring a tight fit without over-tightening
Fill the extraction flask with solvent and place the solid sample in the extraction tube
Attach the condenser and ensure the siphon tube is correctly positioned
Heat the flask gently to initiate solvent reflux; monitor for consistent siphon action
Run the extraction for the required duration-typically several hours to overnight
Stop heating, disassemble, and collect the extract from the flask for analysis
Clean all glass components with appropriate solvents after use to prevent residue buildup

FAQ

Questions Buyers Ask

What is the difference between ball-shaped and snake-shaped condensers?

Ball-shaped condensers offer compact design and moderate cooling efficiency. Snake-shaped condensers provide longer surface area for better heat exchange, improving condensation in high-volume or high-temperature applications.

Can I use different flask sizes with the same condenser?

No. Condensers are sized to match specific flask taper joints. Use only condensers with matching upper taper joints (e.g., 34/35 mm for 60 ml flask).

What is the siphon tube diameter and why is it important?

The siphon tube has a diameter of Φ6 mm. This size ensures consistent liquid return and prevents clogging during extraction.

How do I know which components to order for a 500 ml system?

For a 500 ml system, order: SE0500B or SE0500S (extractor), SE0500BC or SE0500SC (condenser), SE0500ET (extraction tube), and SE0500F (flask).

Are the components reusable?

Yes. All glass components are reusable and can be cleaned and reassembled after each use.

Do you offer custom sizes beyond 2000 ml?

The standard range goes up to 2000 ml. Custom sizes are available through the Microlab OEM division for bulk or special applications.
