The equipment extracts essential oil and pure dew by distillation, applicable for the common and isolated distillation and extraction process of plant branches, leaves, flowers and grasses with high oil and fats content, animal materials with conventional oils and fats, and aromatic oil components. With an exquisite structure and simple operation, it’s especially suitable for the extraction of essential oil and pure dew in laboratories and at home.

|Condensate Pipe Clamp
1. Place the electric furnace horizontally, and the iron platform next to the electric furnace. Install the flask clamp and cross clamp.
2. Place the two-necked flat bottom distillation flask on the center of the electric furnace and fill the flask with either water or ethanol. (With a low boiling point, the ethanol has a fast heating rate.)
3. Put the extract(It can be extracted as long as it contains essential oil) into the round bottom material flask. And the material flask is connected with the two-necked distillation flask, fixed with a flask clamp and a cross clamp.
4. Install the connecting pipe and the condensate pipe successively, tighten the grinding mouth and fix the condensate pipe with a flask clamp.
5. Install the separator and fix it with a plastic standard clamp.
6. Install a hose long enough on the water inlet and connect the other end to the faucet.
7. After the installation, check whether the instrument is fixed and clamps are fastened.
8. Turning on the electric furnace, it’s normal that the newly used electric furnace will fume, which smells like burnt plastic. Generally, it will be tasteless after heating for 20 minutes. Heat the two-necked flat bottom distillation flask until boiling. The steam will go through the material flask containing extracts, and will flow into the separator after being condensed by the condensate pipe. There will be more and more mixtures in the separator. For a small amount of mixtures, the valve can be opened to release the pure dew, leaving the top essential oil or releasing the essential oil after the distillation. For a large amount of mixtures, the extract can discharge spontaneously when mixtures reach the height of the dew outlet.
Application Methods of the Oil-Water Separator
According to the principle that oil is denser than water, the pure dew will flow out and the essential oil will be left. When reaching the upper branch, the essential oil can flow out from the left oil outlet. If the essential oil can’t reach the upper branch after finishing the distillation, what should be done is to close the valve after separating the pure dew. Then find another container and open the valve to make the essential oil discharge.
Precautions for Use
1. Before use, fix nuts well at the bottom of the iron platform, adjust the position of the cross and iron clamps, and connect the distillation flask with the material flask.
2. The water tank should be higher than the surface of the serpentine condensate pipe. With a syringe, inject about 30ml of water from the water inlet into the condensate pipe.
3. The water will flow out spontaneously when the latex tube is connected well and the water stop clip on the water outlet of the latex tube is loosened. (The Principle of Siphon Phenomenon)
4. The equipment isn’t applicable for the volatile oil with thermal instability.
Extraction Method of Rose Hydrosol:
1. Prepare 100g of rose petals and 200ml of water( If a higher concentration of the pure dew and a more intense aroma are needed, more rose petals can be added with less water.) Put rose petals into the material flask and add a little salt. Then shake the material flask so that it is evenly fused.
2. Open the closed electric furnace until water is heated into boiling and roses become lighter in color.
The distilled steam passes through the steam pipe into the serpentine condenser. With a oil-water separator, the pure dew will be separated.
