Rotary evaporators are indispensable in the realms of food, pharmaceuticals, chemicals, and biopharmaceuticals, serving pivotal roles in pilot tests for concentration, crystallization, drying, separation, and solvent recovery. Equipped with large-capacity and wide-opening rotary evaporation bottles, these devices operate within a water bath, rotating to enable the swift and efficient evaporation of solutions. When paired with devices like circulating water multi-purpose vacuum pumps, diaphragm vacuum pumps, low-temperature circulation pumps, circulating coolers, constant temperature circulators, and low-temperature coolant circulation pumps, they form a comprehensive and highly efficient system. The operational principle is elegantly simple: under vacuum conditions, the rotary bottle is heated at a constant temperature and rotates steadily, forming an expansive film of material on its walls for improved evaporation. The evaporated solvent vapors are promptly cooled by a high-efficiency glass condenser and collected in a recovery bottle, significantly boosting evaporation efficiency. This setup is especially advantageous for concentrating and purifying biological products prone to decomposition and denaturation at elevated temperatures.
