Gas Spargers & Thermometer Pockets
Goel Glass manufactures high-efficiency Borosilicate 3.3 Gas Spargers and thermometer pockets engineered for subsurface gas introduction, accelerated gas-liquid mass transfer, and precise process thermal monitoring in glass reactors, distillation units, and pilot plants. Featuring micro-perforated gas dispersion tips (5 × 1 mm standard hole arrays), our spargers produce fine, uniform micro-bubble distributions that dramatically increase the interfacial contact area between gaseous and liquid phases.
These glass spargers are ideal for catalytic hydrogenation, chlorination, ozonation, oxygen stripping, and inert gas blanketing (such as nitrogen or argon purging) to eliminate dissolved oxygen from sensitive synthesis reactions. Positioned directly beneath or adjacent to the agitator impeller, incoming gas bubbles are sheared and evenly dispersed across the liquid volume, maximizing retention time and reaction yields while preventing bubble coalescence.
For accurate temperature control, our matching Thermometer Pockets (Thermowells) provide a thin-walled, sealed glass sheath that immerses deep into the process fluid. They protect temperature probes (PT100 RTDs, thermocouples, or laboratory thermometers) against aggressive acidic mixtures and hydrodynamic shear, ensuring rapid, reliable thermal sensing without metallic contamination.
