Product Details:

The Dean And Stark Apparatus typically consists of vertical cylindrical glass tube, often with a volumetric graduation along its full length and a precision stopcock at its lower end, very much like a burette. The lower end of a reflux condenser fits into the top of the cylinder. Immediately below the joint between the condenser and the cylinder is a sloping side-arm that joins the cylinder to a reaction flask. The lower end the side-arm turns sharply downward, so that the side-arm is connected to the reaction flask by a vertical tube. The reaction flask is heated. Boiling chips within it assist with the calm formation of bubbles of vapor containing the reaction solvent and the component to be removed. This vapor travels out of reaction flask up into the condenser where water being circulated around it causes it to cool and drip into the distilling trap. Here, the immiscible liquids separate into layers (water below and solvent above it). When their combined volume reaches the level of the side-arm, the upper, less-dense layer will begin to flow back to the reactor while the water layer will remain in the trap. The trap will eventually reach capacity when the level of the water in it reaches the level of the side-arm. At this point, the trap must be drained into the receiving flask. The process of evaporation/ condensation/ collection may be continued until it ceases to produce additional amounts of water. Made of 3.3 borosilicate glass. Uniform wall distribution of the Flask makes it suitable for heating. Consists of a graduated Receiver with 0.1 intervals.

Product Details:

Organic compounds are separated using steam, so as not to degrade the essential oil. Essential oils are what is used for perfume, food, medicines or atomizers. The Clevenger Apparatus conducts the distillation process by boiling, condensing and decantation to separate the oil. This is also the official standard method for extracting essential oils for quality control. When this method is used, there is less loss of the organic matter that the oil is being desecrated from. In this standard method, the distillation procedure is closely defined vegetable products, according to the reference method indicated in the standard is done with steam distillation, collecting the distillation product in xylene. The Clevenger Apparatus comes in several sizes to accommodate the size of the organic material that is being distilled. The Clevenger appears like a glass double boiler with several valves to increase the temperature or release the steam to lower the temperature; this has been the main method of flavor extraction. The Clevenger Apparatus equipment ranges in cost depending upon the size of the tool needed.
