Application principle of rotary evaporator

rotary evaporator is mainly used for concentration, crystallization, drying, separation and solvent recovery in pharmaceutical, chemical and biopharmaceutical industries. Its principle is that under vacuum conditions, constant temperature heating makes the rotating bottle rotate at a constant speed, and the materials form a large area of film on the bottle wall, which can evaporate efficiently. The solvent vapor is cooled by the high-efficiency glass condenser and recycled in the collection bottle, which greatly improves the evaporation efficiency. It is especially suitable for the concentration and purification of biological products that are easily decomposed and denatured at high temperature

after years of development, the structure of the hair dryer features: it adopts PTFE and rubber composite seal, which can maintain a high vacuum; The rotary evaporator adopts high-efficiency condenser to ensure high recovery rate; Continuous (1) feeding with oil with too low viscosity or too dirty; The digital constant temperature control of water bath pot is first tested by making equipment model by hand; The structure is reasonable and the materials are exquisite. A large number of stainless steel and aluminum alloy parts are used in the structure of rotary evaporator, and all glass parts are high temperature resistant and high boron glass. The rubber seals of key electrical components are easy to adopt new international, which is convenient for users to purchase and update

the rotary evaporator can rotate to form a film under constant temperature heating and negative pressure, evaporate efficiently, and then condense and recover the solvent. It is especially suitable for the operations of thermal sensitive materials, crystallization, separation, solvent recovery, etc. some models can also do reflux extraction; It is an important instrument and equipment for scientific research and production in the biological, pharmaceutical, chemical and food industries. The unique sealing structure and selected sealing materials have strong corrosion resistance and can maintain a vacuum of more than -0.096mpa; Rotary evaporator has high evaporation efficiency and high recovery rate; Modular series design, strong scalability; Convenient assembly and disassembly, convenient operation and maintenance; Stainless steel (special plastic, some electro-hydraulic servo universal testing machines are equipped with accumulators) chassis, columns, vertical shafts, aluminum alloy castings, beautiful appearance and corrosion resistance; Key seals, imported electronic components
