A small scale Soxhlet extractor used to purify a ferrocene containing compound.

This compound is not well soluble in any solvent, but the gunk what formed next to it is almost insoluble in dichloromethane, so I could purify it with a continous extraction using dichloromethane as a solvent.

The unpure compound was placed on the first level of the extractor on a piece of cotton, some dichloromethane was placed at the bottom and the solvent was boiled. Instead of the glass stopper what is seen on the pics at the top, a condenser was placed and with this, the unpure compound was washed continuously with clean solvent.
