High-efficiency glass column packing for distillation, absorption, and separation applications
Column Packing Overview
Column packing plays a critical role in enhancing mass transfer efficiency in distillation, absorption, and extraction processes. Goel Scientific Glass Works Ltd. offers premium-quality column packing materials, including Raschig Rings and Pall Rings, manufactured from 3.3 borosilicate glass to ensure superior chemical resistance, durability, and process reliability.
Glass column packings provide a high surface area for effective vapor-liquid interaction, resulting in improved separation efficiency, uniform fluid distribution, and minimal pressure drop within the column. Their transparent construction also allows easy visual monitoring of process performance, making them ideal for both laboratory and industrial applications.
Raschig Rings are simple cylindrical glass packings available in sizes ranging from 8 mm to 50 mm. They offer excellent chemical inertness, uniform liquid distribution, and reliable performance in a wide range of separation processes. These packings are especially suitable where purity, corrosion resistance, and thermal stability are essential.
Pall Rings are an advanced version of Raschig Rings, featuring specially designed internal structures and openings. This design enhances vapor-liquid contact, improves flow dynamics, increases separation efficiency, and significantly reduces pressure drop compared to conventional packings.
Manufactured from high-quality borosilicate glass, both Raschig Rings and Pall Rings are:
- Chemically inert and corrosion-resistant
- Non-toxic and contamination-free
- Resistant to high temperatures and aggressive chemicals
- Easy to clean and maintain
- Suitable for laboratory, pilot, and industrial scale operations
These glass column packings are widely used in chemical, pharmaceutical, petrochemical, food, and research industries, where high purity, efficiency, and long service life are essential.

Notes on the Use of Column Packing
- Due to their low bulk densities, Glass Raschig rings are particularly suitable for packing glass columns.
- Generally, the ratio of Column diameter to packing diameter should not be less than 8:1.
- When using smaller packing size, a small layer of larger packing should be used on packing support, to prevent the smaller packing falling through.
- In vacuum application and applications involving high vapour velocities, packing may be lifted and may damage to other parts. To prevent this, a packing retainer (PTFE perforated plates) should be used above the packed section.
