Working principle and structural features of rotary evaporator _ cooler _ recovery _ condenser


Original Title Working Principle and Structural Features of Rotary Evaporator Rotary evaporator is a kind of evaporation instrument widely used in laboratory which is suitable for the concentration of trace components wiped film distillation and the rapid evaporation of a large amount of solvent and the reaction process requiring stirring and reflux operation Under the action of high-efficiency cooler the vapor can be quickly liquefied thus accelerating the evaporation rate The working principle of the rotary evaporator is as follows under the vacuum condition constant temperature heating is carried out so that the rotary bottle rotates at a constant speed materials form a large-area film in the bottle wall and are evaporated efficiently and the solvent vapor is cooled by a high-efficiency glass condenser and recovered in a collecting bottle so that the evaporation efficiency is greatly improved and the rotary evaporator is particularly suitable for concentration and purification of biological products which are easily decomposed and denatured at high temperature Rotary evaporator is mainly used for concentration drying crystallization solvent recovery and separation in biopharmaceutical rotary vacuum evaporator chemical and other industries


The structural features of the rotary evaporator are as follows 1 Continuous feeding is available 2 the use of rubber and PTFE composite seal can maintain a high degree of vacuum 3 Digital thermostatic control of water bath 4 Explosion-proof rotary evaporator adopts high-efficiency condenser to ensure high recovery rate And 5 that material are exquisite and the structure is reasonable All glass parts are made of high temperature rotovap distillation resistant high-boron glass and the key parts of electrical appliances are sealed with rubber all of which are new international which is convenient for users to purchase and update; a large number of mechanical structures are made of aluminum alloy and stainless steel 。 The structural characteristics and working principle of the rotary evaporator are introduced above and we have a certain understanding It can be seen that the rotary evaporator has reasonable structure and high working efficiency which is worth promoting Return to Sohu to see more Responsible Editor toptiontech.com
