Our Best-Selling Electric Rotary Evaporator

 

 

Large Electric Rotary Evaporator
Large-scale rotary evaporators are mainly used in small trials, pilot trials and production in the fields of biology, pharmaceuticals, chemicals, food and other fields. Like the large-capacity, large-diameter rotary evaporator flask, when placed in a water bath, the solution is rapidly diffused and evaporated as it is rotated and heated at the same time.


20l Rotary Evaporator
When the temperature is higher than the set temperature, the heating tube will automatically stop heating. The heating pot has a safety handle, moderate volume, and rapid heating. The heating pot uses a Teflon composite pot, which is easy to clean.


Rotary Vacuum Evaporator
The rotary evaporator is developed under vacuum negative pressure conditions using the principle of constant temperature heating and thin film evaporation. The glass rotary bottle is rotated at a constant speed using stepless speed regulation, and the material forms a large area of uniform film on the bottle wall. The rotary bottle is then evenly heated by an intelligent constant temperature water-oil bath.

Functions of Electric Rotary Evaporator

 

 

Distillation

One of the core functions of electric rotary evaporator is distillation. By applying heat and reducing pressure, electric rotary evaporators can separate solvents from compounds, enabling the purification of substances. This process is essential in chemical synthesis, where pure products are required.

Extraction

Electric rotary evaporators are also used for the extraction of compounds from mixtures. By selectively evaporating solvents, researchers can isolate specific components, making this function invaluable in fields such as pharmacology and natural product research.

Concentration

Electric rotary evaporators are adept at concentrating solutions by removing excess solvent. This is particularly useful in preparing samples for further analysis or use in experiments.

Recrystallization

In certain cases, electric rotary evaporators can aid in the recrystallization of compounds by controlling the evaporation rate and temperature, which helps in obtaining pure crystals.

Drying

Electric rotary evaporators can effectively remove residual solvents from solid samples, ensuring accurate analysis and subsequent processes.

 

 
Key Components of Electric Rotary Evaporator
 
01/

Rotating evaporation flask: A round-bottomed flask is made of glass to hold the concentrated sample, flask is available in various sizes. It is usually placed in an oil or water bath for heating.

02/

Heating bath: Heating bath is used to heat the liquid inside the flask to ensure a consistent and accurate temperature during evaporation.

03/

Drive motor: Provides power to the rotary evaporation flask so that the liquid inside can be heated more evenly to facilitate evaporation.

04/

Condenser: The condenser is the key component of rotary evaporation and is made of a spiral glass tube. The vapor is condensed back to liquid form in the condenser.

05/

Vacuum pump inlet: The vapor is reported faster by increasing the pressure and decreasing the temperature.

06/

Receiving flask: The condensed solvent is collected in a receiving flask located below the condenser. This flask can be heated if required to promote further evaporation of the collected solvent.

FAQ

 

Q: What's the key technology of electric rotary evaporator?

A: The gas tightness of the system is the key point. The system can maintain a high vacuum degree under any circumstance, whether the solvent is corrosive or it moves unstably. Henan Lanphan' s R series instrument adopts a double seal by using both PTFE and rubber, which possesses a reliable gas tightness. It is capable of standing all sorts of solvents and maintaining a high vacuum degree above -0.096MPa.

Q: What are the conditions for electric rotary evaporator?

A: You'll need a coolant temperature of 10℃ and a bath temperature of 50℃ to be operating under optimal conditions.

Q: How to reduce pressure in electric rotary evaporator?

A: The vacuum tap, and the air bleed tap, can both be used to control the vacuum in the system. For example, during the evaporation, the vacuum can be increased (i.e. the pressure in the system can be reduced) by opening the vacuum tap fully, and closing the air bleed tap fully.

Q: How to select all kinds of electric rotary evaporators?

A: The electric rotary evaporators with various volumes are applicable for different situations. Hence, all kinds of electric rotary evaporators can be selected properly in terms of their different volumes. According to the solvent volume, 2L, 3L, 5L's machine is fit for lab and sample test; 5L, 10L, 20L's machine is fit for medium experiment; 20L, 50L's machine is fit for medium experiment and production, especially suitable for the extraction of metal ion-avoiding polluted material.
