Rose petals e. g. contain very little oil. 1: Stirrer bar (magnet) – not necessary 2: Still pot 3: Distillation path 4: Thimble 5: Material to be extracted 6: Siphon top 7: Siphon exit (When the level of the solvent in the thimble rises to the siphon top a suction effect occurs and the liquid pours into the flask below) 8: Expansion adapter (necessary if the Soxhlet and the condenser don’t match) 9: Condenser 10: Cooling water in 11: Cooling water out. Add: Yard 26, Dongqing Street, Zhengzhou, Henan, China. The vapours liquefyin the condenser and the water oil mixture is collected in theflask to the right.
This ingenious device helps to extract the plant material repeatedly with boiling liquid in a continuous process.
The method is especially suited for essential oils that would decompose at higher temperatures.
As a result the boiling point of the mixture is lower than that of its components, because the boiling point is reached as soon as the vapour pressure equals the air pressure that prevails.

This water has also to be heated. This is why the pressures of their vapours above the liquid mixture add: Pvapour-total = Poil-vapour + Pwater-vapour. It evaporates, is re-condensed by the cooler and collets in the flask below the cooler. Thesteam will carry the essential oil with it.

Fill the solution into a round bottomed flask and remove the solvent with the help of a liquid jet vacuum pump while heating the solution gently in a water bath.
After separating itfrom water the solution has to be dried and then the solvent is removedas described in the first and second example. This is a process where steam goes through the plant leaves to extract the oils. The remaining oily liquid is the essential oil. Typical Applications for Ultra-Low Temperature Deep Freezers. Rose petals have to be harvested in the morning and are processed immediately afterwards. Large amounts of plant material are needed to gain a few millilitres of essential oil.
