Fractionation column packing glass spring packing diameter 7mm length 10-20mm, glass spring packing is mainly used in fine chemical, pharmaceutical and other industries laboratory distillation device, small test, pilot test and scale production of packing tower, packing function: The contact area is increased when the gas phase and liquid phase pass through, and strong mixing is obtained, which can improve the flow efficiency, and is used in the packing of chromatography column and separation column. It has the characteristics of corrosion resistance and high filtration efficiency. The diameter and length of the product can be manufactured according to requirements. The conventional product is 3-8mm in diameter and 6-20mm in length. Our standard glass spring packing ø 4, length 10-20mm, bulk density of 350kg/m3. Glass spring packing is mainly used for corrosive materials, such as organic acids, some things are not allowed to contact with iron ions, glass spring packing is the preferred packing of laboratory distillation unit, pilot test, pilot test and large-scale production. It can be used for scientific research, education and new product development of organic chemical industry, petrochemical industry, fine chemical industry, biological pharmaceutical chemical industry, etc.
