It contain siphon top and siphon exit .Cooling water in and cooling water out
Demonstration of working of Soxhlet Appratus
- The source material containing the compound to be extracted is placed inside the thimble.
- The thimble is located into the main chamber of Soxhlet extractor
- The extraction solvent used is placed in distillation flask. Solvent may be ethanol, methanol distilled water ,acetone, chloroform etc.
- .The flask is placed in heating chamber ,proper temperature is maintain according to which solvent is used for extraction
- The Soxhlet extractor is placed a top the flask
- .A reflux condenser is placed a top the extractor.
- Check the inlet and outlet siphon. Maintain proper temperature suitable for solvent.
- Run this apparatus for 6 to 18 hours.
- Collect the extract from flask filter through filter paper store the extract in amber color bottle in a freeze.
- Use this extract for phytochemical analysis
