A rotary evaporator (rotovap or rotatvap) refers to a kind of equipment for solvent evaporation under reduced pressure, which is composed of a vacuum system, a heated water or oil bath, a condenser and a motor that rotates the evaporation flask. As its name suggests, what is special is that the evaporation flask can rotate. A complete rotary evaporator is generally composed of the following parts, which cooperate with each other and all play an essential role in the working process of a rotary evaporator. 1. Better security. The stainless steel and aluminum alloy are widely used in the mechanical structure, and all glass parts are made of heat-resistant high borosilicate glass, which ensure a better security. Besides, the water/oil bath can be equipped with transparent covers to prevent splashing, and anti-explosion frequency changer and dynamo are available as well. All of these designs contribute to better security. 2. Higher evaporation efficiency. There are several factors contributing to higher evaporation efficiency. Firstly, the rotating flask can rotate at a constant speed, and materials can form a widespread film on the inner surface of the flask, which improves the evaporation efficiency greatly. Secondly, the high-efficiency glass condenser can improve the evaporation efficiency as well. Last but not least, continuous feeding and high vacuum degree are another factors. 3. More convenient operation. It's much more convenient to use a rotary evaporator, because the electrodeless speed regulation, digital display K type sensor and intelligent temperature control and other designs adopted by it.

Introduction to SLYD Series Dyno The SLYD dynamometer adopts AC frequency conversion feedback loading, and the loading energy is fed back to the power grid through the AC load generator; the torque and speed are measured directly by the torque sensor; Technical Advantages 1. Energy saving of electric dynamometer: the basic principle of hydraulic and eddy current dynamometer is to convert the mechanical energy generated by the prime mover into heat energy, which will be taken away by water cooling. The energy generated by the prime mover can not be recovered, and energy consumption is also required in the conversion process. However, the electric dynamometer can convert the mechanical energy generated by the prime mover into electrical energy and feed back to the internal power grid for other equipment to use. 2. The loading mode of electric dynamometer: the hydraulic dynamometer can only be loaded in one direction, and the loading performance will be worse when the speed is lower than a certain value; it can not be used as reverse towing equipment, and it needs to be equipped with additional driving equipment when the engine mechanical efficiency test is required. The eddy current dynamometer can be bi-directional loading, but its loading performance is worse than that of hydraulic dynamometer at low speed, so it can not be used as reverse towing equipment. When the engine mechanical efficiency test needs to be done, additional traction equipment should be equipped.
