Product features

Oblique drying tube is a glass instrument used in chemical laboratories to dry gases or remove impurities from gases. The main body is an oblique glass tube, usually made of high borosilicate glass, with good chemical and thermal stability. One end is with standard ground mouth, with a variety of sizes, such as 14#, 19#, 24#, etc., which can be tightly connected with other standard ground mouth instruments to ensure the sealing of the device. The tube is generally filled with desiccant, such as anhydrous calcium chloride, silica gel, soda lime, etc., which is used to absorb moisture or other impurities in the gas. When the gas containing moisture or impurities passes through the drying tube, the desiccant in the tube will adsorb or absorb the moisture or impurities in the gas, so that the gas is dry and pure.

Oblique drying tube is easy to connect, and the standard ground mouth design enables it to be quickly connected to a variety of instruments, making it more convenient to build experimental equipment; the drying effect is good, and the oblique structure can increase the contact area and contact time between the gas and the desiccant, thereby improving the drying efficiency; One end is standard ground mouths, which are tightly connected and can be easily assembled with other standard ground mouth instruments to ensure the sealing of the device; the oblique design increases the contact area and time between the gas and the desiccant, thereby improving the drying and impurity removal efficiency; the material is excellent, usually made of high borosilicate glass, with good chemical and thermal stability, and can adapt to a variety of chemical environments and temperature changes; the visibility is strong, and the transparent glass material makes it easy to observe the state of the desiccant and the gas flow in the tube; there are various specifications, with different sizes, which can be selected according to experimental needs and adapted to different experimental equipment.

Product applications

(1) Gas drying and impurity removal: In various gas-related experiments, it is used to remove moisture and impurities in the gas to ensure that pure and dry gas is obtained, such as drying and purifying after the preparation of hydrogen, oxygen and other gases.

(2) Protecting the reaction device: Installed at the inlet and outlet of the water-sensitive chemical reaction device to prevent water vapor from the outside air from entering, avoiding affecting the reaction or causing the product to deteriorate.

(3) Special gas preparation: In certain cases, as a special gas generating device, the gas is prepared by the reaction between the solid in the tube and the introduced gas, such as the reaction of carbon dioxide and sodium peroxide to prepare oxygen.
