Borosilicate Glass Column Adaptors
Goel Glass manufactures high-precision Borosilicate Glass Column Adaptors designed to seamlessly transition between differing nominal pipe diameters and connect column sections to condenser heads, reflux dividers, vapor lines, and reboiler vessels. Fabricated from Type 3.3 Borosilicate glass, these adaptors provide optimal hydrodynamic transitions that minimize hydraulic turbulence and pressure loss.
Each adaptor is engineered with precision-aligned flat/buttress flanges. Side branches (DN2) can be integrated with varying nominal dimensions (up to DN1) to accommodate thermometer sensor pockets, reflux return lines, liquid sampling systems, or pressure balancing connections while maintaining total corrosion resistance.

Key Design Features
- Near-Universal Chemical Resistance: Constructed from Borosilicate 3.3 glass, impervious to hot aggressive acids, halogen vapors, and volatile solvents (excluding HF and hot concentrated caustics per Technical Information).
- Hydrodynamic Transition: Smooth conical reducers prevent liquid hold-up and minimize vapor turbulence across column diameter changes.
- Versatile Branch Configurations: Side ports (DN2) allow flexible instrumentation immersion (thermowells, pH probes, pressure transducers) or liquid reflux returns.
- Interchangeable Standard Couplings: Compatible with standard industry backing flanges and PTFE envelope gaskets.
Industrial Applications
Goel Glass column adaptors are installed in distillation towers, extraction plants, reaction headers, and chemical pilot units across North America. They facilitate modular scale-up, diameter step-downs between packed beds and condenser manifolds, and custom instrument connections.
