Industrial Borosilicate Stirred Reaction Units
Goel Glass manufactures high-performance Borosilicate Glass Reaction Units designed for liquid-phase chemical synthesis, controlled reagent addition, and simultaneous reflux distillation under stringent pilot plant and production conditions. Each system features a premium Borosilicate 3.3 reaction vessel suspended in a thermostated electric heating bath or heating mantle, supported by a heavy-duty stainless steel tubular frame.
The unit is equipped with a variable-speed motorized mechanical stirrer drive with a gas-tight PTFE mechanical gland seal, ensuring contamination-free agitation even under continuous deep vacuum. Reagent dosing is accomplished via a graduated cylindrical addition vessel with pressure equalization tubing. Overhead vapors pass through an engineered glass vapor adapter into a high-surface coil condenser, allowing continuous total reflux or forward distillation into a dedicated condensate receiver vessel.
