Column packings such as Raschig Rings and Pall Rings made from 3.3 borosilicate glass are widely used in distillation, absorption, and extraction processes. They provide a large surface area for vapor-liquid contact, ensuring high separation efficiency and low pressure drop inside glass columns. Raschig Rings are cylindrical glass pieces ranging from 8 mm to 50 mm in size, offering uniform liquid distribution and excellent chemical resistance. They are suitable for laboratory-scale as well as industrial-scale applications, especially where purity and transparency are critical. Pall Rings are a modified form of Raschig Rings with additional windows and internal structures, allowing better gas-liquid flow dynamics, higher efficiency, and reduced pressure drop. Both types are chemically inert, non-toxic, easy to clean, and resistant to high temperatures and corrosive media, making them ideal for use in chemical, pharmaceutical, petrochemical, and food industries.
