Borosilicate Glass Column Packing Supports
Goel Glass supplies precision-engineered Borosilicate Glass Column Packing Supports designed to retain random and structured column packings (such as Raschig rings and Pall rings) inside industrial distillation, fractionation, and absorption columns. Column sections are manufactured with an integrated internal fused shelf where the packing support plate securely rests without slipping or shifting.
Packing supports are constructed from fused high-purity borosilicate glass rods (Type A) engineered to deliver high cross-sectional free area (up to 65%) to ensure minimal pressure drop, uniform vapor-liquid distribution, and protection against column flooding under elevated throughput.

PTFE Perforated Plates (Packing Retainers)
Manufactured from pure virgin PTFE, these perforated plates function as packing retainers positioned directly above the packed bed. Under high vapor velocities or vacuum surge conditions, loose column packing can lift or fluidize, potentially causing entrainment or mechanical damage to upper condensers and reflux dividers. PTFE perforated plates prevent packing displacement and can be directly clamped between glass pipe sections and flanged column components without requiring additional gaskets.

Notes on Use of Column Packing
- Due to their low bulk densities, Borosilicate 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 for optimal distribution.
- When using smaller packing sizes, a small layer of larger packing should be placed directly on the packing support to prevent smaller packing from falling through.
- In vacuum operations and applications involving elevated vapor velocities, packing may fluidize or lift. To prevent column damage, a PTFE perforated plate retainer should be installed above the packed section.
Industrial Applications
Goel Glass column packing supports and PTFE retainers are extensively deployed in distillation columns, absorption towers, extraction units, and solvent recovery systems across the chemical, pharmaceutical, petrochemical, and research laboratory sectors in North America.
