Rotary Evaporator and other types of evaporator Rotary evaporators are compact, compact, efficient, intuitive, and free from metal ion contamination. Applicable to the laboratory, production pilot and the extraction of valuable materials, its sealing performance is comparable to foreign machines. Under the corrosion of various solvents and in the state of motion, whether the high-frequency infrared carbon-sulfur analyzer system can maintain high vacuum is the main standard for measuring the rotary evaporator zui. It is sealed with Teflon material and glass. solvents, persistent and reliable air tightness can be maintained 0. 098MPa or more high vacuum. Â Factors affecting the efficiency of the rotary evaporator are the same specifications: steam temperature, vacuum and cooling water temperature. Due to the heat resistance of some materials, it is impossible to increase the steam temperature indefinitely during work. Therefore, high vacuum and low cooling water temperature are the two main factors for improving efficiency. The difference between the vertical condenser and the oblique condenser The vertical condenser is gradually welcomed due to its small footprint. The large-capacity evaporator generally uses a vertical condenser, but in essence, the two instruments are indistinguishable. Â Â A rotary evaporator and the level of regulation: manual lifting, rotating machine column above the handwheel, into cis rise, reversing decline. Electric lift , the hand touches the rise button and the main unit rises , and the hand touches the down button to lower the main unit . There are two outer joint condenser is connected with the cooling water, a water connection, then the other end of the water, running water in general, the lower the better the effect of the condensate temperature. The upper port is equipped with a vacuum connection , and the vacuum pump is connected to the vacuum tube for vacuuming . Before turning on the rotary evaporator, turn the speed control knob to the left , press the power switch indicator light , then slowly turn to the right to the required speed . Generally, the large evaporation bottle is used , the low speed , the viscosity is higher. Speed . The flask is standard interface 24, random attachment 500ml, 1000ml two kinds of the flask, the amount of solution generally is suitably not exceed 50%.
