Model HSHD-2000B Rotary evaporators are mainly used for concentration, crystallization, drying, separation, and coal recovery in industries such as pharmaceuticals, chemical engineering, and biopharmaceuticals. The principle is: under vacuum conditions, constant temperature heating causes the rotating bottle to rotate at a constant speed, forming a large film on the bottle wall and efficiently evaporating the material. The dissolved coal vapor is cooled by an efficient glass condenser and recovered in a collection bottle, greatly improving the evaporation efficiency. It is particularly selected for the concentration and purification of biological products that are prone to decomposition and denaturation at high temperatures.
