Rotary Vacuum Evaporator Overview
Goel Scientific manufactures precision rotary vacuum evaporators (rotary film evaporators) for laboratory, pilot and industrial use . These systems enable efficient evaporation of solvents under reduced pressure — lowering the boiling point and enabling gentle removal of volatile compounds . The units typically comprise a rotating flask, heating bath, condenser, vacuum controller, and receiver, all integrated to deliver controlled, reproducible performance . Goel’s models are designed for durability, chemical resistance, and automation, with capacities from small benchtop sizes up to large industrial volumes .

Applications
These rotary vacuum evaporators are used broadly across:
– **Chemical & Pharmaceutical industries** for solvent recovery, concentration of intermediates, purification, and distillation of temperature-sensitive compounds
– **Biotechnology & Life Sciences** laboratories for concentrating extracts, drying samples, or solvent removal under mild conditions
– **Food, Aroma & Natural Products** for extraction, concentration of aromatic compounds, and distillation of flavor / fragrance fractions
– **Environmental & Analytical Labs** for sample preparation (e.g. evaporating solvents before analysis) and cleanup of waste solvents
