Grinding volatile oil analyzer/volatile oil extractor/model: HAD-500ML

Volatile oil, also known as essential oils in English, is a general term for a type of volatile oily component that exists in plants and has an aromatic odor. It can be distilled with water vapor and is immiscible with water. Volatile oil is a mixture with complex components. Essential oils are mainly prepared by steam distillation and pressing methods. Terpenes are commonly found in volatile oil components, as well as small molecule aliphatic compounds and small molecule aromatic compounds.
Volatile oils are mostly colorless or light yellow oily liquids, often with a special aroma or spicy taste. The specific gravity is between 0.850-1.180, easily soluble in anhydrous ethanol, ethers, chlorine, carbon disulfide, and fatty oils, but difficult to dissolve in water. Volatile oils have certain optical rotation and refractive index, and refractive index is an important basis for identifying the quality of volatile oils. If left for too long, it is prone to oxidation and polymerization, resulting in darkening of color or resin like appearance. Therefore, it should be stored in a sealed, low-temperature, and dark place------------ The information is available for reference
