No matter laboratory rotavapor or large capacity industrial rotary evaporator, most TOPTION customers prefer to choose vacuum pump, vacuum controller and chiller to equipped with rotary evaporator. So how does a rotary evaporator working? Why vacuum pump and vacuum controller are identified as prerequisite device of rotavapor?
Firstly please check the below laboratory experiment's result from TOPTION specialist practice --
Using TOPTION "1-2L Rotary Evaporator " to deal with solvents of low boiling point Receiving Rate 99% under below settings, evaporation process were quick and stable. System vacuum is well controlled by Vacuum Controller, which enables either heating (evaporation) or cooling (receiving) efficiency going to max.
Experimental Data | Working Parameters | Working Efficiency | |||
Solvent | Cooling Temp. | Bath Temp. | Vacuum | Evaporating Speed | Receiving Rate |
Ethanol-C2H6O | ＜5℃ | 70℃ | 10.2kpa | 2.2L/hr | 98.70% |
Acetone-C3H6O | ＜-2℃ | 54℃ | 37.7kpa | 5.2L/hr | 99.40% |
Chloroform-CHCI3 | ＜-2℃ | 58℃ | 32.8kpa | 6.0L/hr | 99.00% |
- The data is collected in test of 1-2L TOPTION Rotary Evaporator. Condition: RT22℃, Rotation flask 1000ml, Charging volume 500ml.
- To get max vaporization speed, heating temperature shall be 40℃ higher than that of boiling temperature of solvent.
Do you have got the reasons why most customers prefers to choose vacuum pump and vacuum controller for their laboratory evaporation system?
1. Vacuum pump guarantee the vacuum system of rotary evaporator, in order to improve the evaporation and receiving effection, finally make your research more efficient. Under vacuum condition, samples could be sucked in rotating flask directly, which could make your reseach more convenient and save time.
2. Samples' bolling point will decrease, which means evaporation could start when sample haven't reach its boiling point, finally improve your research efficient greatly.
