Performance Analysis and Functional Features of Rotary Evaporator

       The rotary evaporator adopts the stepless speed control to drive the distillation bottle to rotate at a constant speed, so that the solution retained on the inner wall of the distillation bottle forms a film to increase the evaporation area, and the water temperature of the water bath placed in the distillation bottle is adjusted to the required amount in advance, and the condensation is performed. The tube is connected to the vacuum pressure, so that the solution in the bottle is heated, diffused and evaporated under a negative pressure, and the evaporation efficiency is doubled, and the solution is prevented from boiling. The instrument is simple in operation and remarkable in effect, and is suitable for concentration, drying, crystallization or recovery of various solutions. It is an ideal equipment for medical, chemical, laboratory testing and scientific research units. The rotary evaporator can be rotated under constant temperature heating and under negative pressure to form a film, evaporate efficiently, and then condense and recover the solvent. It is especially suitable for the concentration, crystallization, separation and solvent recovery of heat sensitive materials. Some models can also be used for reflux extraction. Rotary evaporators are important equipment for scientific research and production in the biological, pharmaceutical, chemical, food and other industries.
1.Rotary evaporator function and features:
（1）The main body bracket is made of stainless steel + aluminum alloy, the structure is reasonable, and the materials are exquisite.
（2）The rotary evaporator sealing system is sealed with a combination of Teflon and imported fluororubber to maintain a high vacuum.
（3）The vacuum gauge shows a real-time vacuum with a vacuum of 0.098 MPa.
（4）The glass components of the rotary evaporator are all made of borosilicate glass (GG-17), which is resistant to high temperatures and corrosion.
（5）Continuous feeding is convenient for customers, and the valve type feeding tube is sleeved with PTFE tube.
（6）Upright three-layer serpentine coil condenser, main cold + cold double condenser, ensuring high recovery and additional material tube.
（7）Microcomputer type ON-OFF power switch control.
（8）The digital display of the bath pot and the intelligent constant temperature control, the K-type sensor transmits the temperature quickly and accurately.
（9）Frequency control (0-120rpm), digital display of speed, knob setting, easy to operate.
2.The rotary evaporator performance overview has the following points:
（1）long-lasting seal - from the seal design and material selection to ensure the corrosion resistance and long life of the dynamic seal system.
（2）the bath pot lift - the glass is fixed, the glass is not easy to damage during operation.
（3）precision intelligent temperature control, bath temperature fluctuation is one-tenth of the ordinary two-position temperature control. Can reduce the amount of material. The use of non-contact technology, no spark, safety, durability.
（4）the bottle-removing device - rotary evaporator can easily retract the rotating bottle to reduce glass damage.
（5）low temperature cold trap - condensed with ice, dry ice, suitable for low boiling point solvent recovery.
（6） F4 socket - can greatly reduce the phenomenon of "killing" of glass grinding, reduce damage and increase air tightness.
