R501 rotary evaporator is mainly used for concentration, crystallization, drying, separation, and solvent recovery in pharmaceutical, chemical, and biopharmaceutical industries. The principle is: under vacuum conditions, constant temperature heating is used to make the rotating bottle rotate at a constant speed, and the material forms a large area thin film on the bottle wall for efficient evaporation. The solvent vapor is cooled by an efficient glass condenser and recycled into a collection bottle, greatly improving evaporation efficiency. Especially suitable for the concentration and purification of biological products that are prone to decomposition and denaturation at high temperatures. Related technical parameters and configuration: Motor power: 40W, speed: digital display, 10-90r. p.m lifting mechanism: water bath pot lifting, glass part fixed, more safe and reliable.
