Product features

Distilling head is a key glass instrument used for fractionation operations in chemical experiments. It can separate mixed liquids according to the different boiling points of each component. It is usually made of glass and has a relatively complex overall structure. It generally has a vertical main tube to guide the mixed vapor to rise. There are multiple side tubes on the main tube, which are used to connect thermometers, condensers, and receiving bottles. The ground mouth of the fractionating head is its important feature. These ground mouths are all standard sizes and have high-precision processing technology. They can be tightly connected with other glass instruments with standard ground mouths to ensure the sealing of the device.The working principle of the distilling head is based on the characteristics that different substances have different boiling points. When the mixed liquid is heated to boiling, the generated vapor enters the distilling head to separate the components with different boiling points. The distilling head can use the temperature gradient and multiple vaporization-condensation processes in the fractionation column to effectively separate the components with similar boiling points and improve the separation purity. It is easy to operate and can be separated repeatedly, which is suitable for experiments and production of different scales.

Distilling head is made of high borosilicate glass, which is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. Due to its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light sources, craft jewelry and other industries.The surface is smooth, no bulges, thickened glass, durable and highly transparent. Easy to observe, fine frosting.

Product applications

(1) Laboratory: used for separation and purification of organic compounds, such as separation of product mixtures in the preparation of ethyl acetate; determination of the boiling point of compounds by recording the distillation temperature through fractionation; separation of azeotropic mixtures, such as separation of ethanol and water azeotropes by special methods.

(2) Industrial production: in petroleum refining, crude oil is fractionated to obtain gasoline, diesel and other products; in the production of fine chemical products, it is used for separation and purification of mixtures in small and pilot tests, such as separation of products in the production of menthol.
