Rotary Evaporator 10l Automatic Lift With Recirculating Plate Chiller and Arv

A 10L Automatic Lift Rotary Evaporator is a laboratory device used to efficiently remove solvents from a mixture through evaporation and distillation, often employed in chemistry, pharmaceuticals, cannabis extraction, and other research and industrial applications. The 10-liter capacity indicates the size of the evaporating flask, making it suitable for handling relatively large volumes of solvent. The automatic lift feature allows for easier and more precise operation, enhancing efficiency and safety during the distillation process.

Key Components of the 10L Automatic Lift Rotary Evaporator:

1. Rotary Evaporating Flask (10L Capacity):

   • The rotary flask is where the sample liquid to be evaporated is placed. The 10L flask is made of borosilicate glass, which is chemically resistant and can withstand high temperatures. It rotates to increase the surface area of the liquid, promoting faster and more efficient evaporation.
   • The large volume (10L) makes it suitable for applications that require the distillation of substantial quantities of liquid.

2. Automatic Lift Mechanism:

   • The automatic lift feature allows the evaporating flask to be automatically raised and lowered into or out of the heating bath. This eliminates the need for manual handling, improving safety and convenience.
   • The lift ensures that the flask is positioned optimally for heating, rotation, and vapor collection. It can also help with easy flask removal after the evaporation process is completed.

3. Rotary Motor:

   • The rotary motor drives the rotation of the evaporating flask. The rotation creates a thin film of liquid along the inner surface of the flask, which increases the surface area and facilitates efficient solvent evaporation.
   • The motor is adjustable, allowing for control of the rotation speed depending on the nature of the liquid and the solvent being evaporated.

4. Heating Bath:

   • The heating bath, typically filled with water or oil, surrounds the evaporating flask and heats it to the desired temperature. The bath is essential for providing uniform heat to promote evaporation.
   • The temperature of the bath is adjustable via a digital controller for precise control, ensuring that the liquid in the flask evaporates at a controlled rate without overheating.

5. Condenser:

   • The condenser is responsible for cooling the solvent vapor as it rises from the flask. The condenser cools the vapor back into liquid form, where it is collected in a receiving flask.
   • The condenser usually has an inlet for coolant (like water) and an outlet for the condensed liquid. It’s typically made of glass and designed as a coiled tube to maximize surface area for efficient condensation.
   • IMPORTANT!!!the recieving flask on this model has a shut of valve that allows the recieving flask to be emptied while still keeping the system under vacuum this allows for continual process.

6. Vacuum System:

   • The vacuum lowers the pressure inside the evaporating flask, which in turn reduces the boiling point of the solvent, allowing it to evaporate at a lower temperature.
   • The system consists of a vacuum pump the ARV 8, this pump is designed to be run for long periods of time
   • vacuum valve to control and monitor the vacuum level. Lower pressure speeds up the evaporation process and prevents thermal degradation of heat-sensitive compounds.
   • Vacuum control is crucial for fine-tuning the evaporation rate and ensuring that the process is efficient.

7. Receiving Flask:

   • The receiving flask is where the condensed solvent is collected. After the vapor condenses in the condenser, the liquid flows into the receiving flask.
   • The receiving flask is typically placed below the condenser and is large enough to accommodate the volume of condensed solvent.
   • this model allows for continues evaporation as the recieving flask can be isolated leaving the rest of the system under pressure 

8. Control Panel:

   • The control panel is an integral part of modern rotary evaporators, especially automatic ones. It allows the user to monitor and adjust parameters such as:
     • Rotation speed
     • Heating temperature
     • Vacuum pressure
     • Lift height (automatic control)

Operation Process:

1. Setup:

   • The solvent or sample to be evaporated is placed in the 10L rotary flask. The flask is then connected to the motorized lift system and the condenser.
   • The heating bath is filled with water or oil and set to the appropriate temperature for the solvent being evaporated.
   • The system is connected to a vacuum pump to reduce the pressure.

2. Evaporation:

   • Once the system is activated, the rotary flask begins rotating. The motorized lift lowers the flask into the heated bath, and the liquid begins to evaporate under the reduced pressure of the vacuum.
   • The cooling condenser collects the vapor and condenses it back into liquid form, which is collected in the receiving flask.
   • The process continues until the desired amount of solvent has been evaporated, leaving behind the concentrated material in the rotary flask.

3. Collection:

   • Once evaporation is complete, the receiving flask holds the condensed solvent, which can be reused or further processed.
   • The flask is lifted out of the bath, and the system can be turned off and cleaned for future use.

Applications:

• Solvent Recovery: Recovering solvents such as ethanol, methanol, acetone, and others in chemical and pharmaceutical laboratories.
• Essential Oils Extraction: Extracting oils from plants in the cosmetic, pharmaceutical, and food industries.
• Cannabis and Hemp Extraction: Recovering solvents like ethanol after cannabis or hemp extraction to concentrate the cannabinoids.
• Chemical Synthesis and Purification: Removing solvents after chemical reactions or purifying compounds.

Advantages:

• Large Capacity: The 10L flask size makes it ideal for handling larger volumes of liquids compared to smaller models.
• Automation: The automatic lift mechanism and precise control over parameters make the rotary evaporator more user-friendly and efficient.
• Reduced Heat Degradation: The vacuum system lowers the boiling point of solvents, allowing for evaporation at lower temperatures, which reduces the risk of thermally sensitive materials being degraded.
• Labor-Saving: Automation and ease of use reduce the need for constant supervision, making the process more efficient.
• Consistent Results: Automatic control over key parameters ensures reproducible results with minimal operator error.

Conclusion:

A 10L Automatic Lift Rotary Evaporator is a versatile, high-capacity laboratory instrument designed for efficient solvent evaporation. With its automatic lift, temperature and vacuum control, and large evaporating flask, this type of rotary evaporator is ideal for applications requiring the distillation of larger volumes of liquids while maintaining precision, safety, and ease of use.
