Rotary Evaporators 50l

Rotary Evaporators 50l

A 50L manual lift rotary evaporator is a large-scale laboratory instrument designed for efficient solvent evaporation and distillation processes. It is specifically suited for applications that require the handling of larger volumes of solvents or chemical solutions. The 50L capacity indicates that the rotary flask can hold up to 50 liters of liquid, making this device ideal for industrial-scale or pilot plant operations. Here’s a detailed description of its key components and features:

1. Rotary Evaporator Main Unit

• Size/Design: The main unit of a 50L rotary evaporator is larger than smaller models, designed to fit on industrial or lab benches. Its dimensions are approximately 1.2 to 2 meters in length and 0.5 meters in width, depending on the layout.
• Material: The unit is made of durable, corrosion-resistant materials such as stainless steel to withstand the demanding environment of large-scale solvent evaporation.

2. Rotary Flask (Evaporation Flask)

• Capacity: The rotary flask has a large 50L capacity, allowing it to hold up to 50 liters of liquid for evaporation. It is made from high-quality borosilicate glass, known for its ability to resist high temperatures and chemical corrosion.
• Shape: The flask is round-bottomed to provide optimal heat distribution and efficient solvent evaporation. Its size and volume make it appropriate for large-scale distillation processes.
• Mounting: The flask is mounted on a rotating shaft that can be manually raised or lowered, depending on the desired position.

3. Manual Lift System

• Lift Mechanism: The rotary evaporator uses a manual lift system, where the operator can manually raise or lower the flask to adjust its position relative to the heating bath. This system is useful for maintenance, cleaning, or adjusting the flask’s height during operation.
• Automatic lift : The Automatic lift arm makes it much easier, accurate and faster when operating the lift arm, at a push of a buttom the heavy rotating flask will lift smoothly out of the heating heat bath.
• Lift Capacity: The manual lift mechanism is typically designed to handle the weight of large 50L flasks and is often operated via a winch or a mechanical handle that adjusts the height smoothly.

4. Heating Bath

• Heating System: A large, thermostatically controlled heating bath is used to heat the evaporation flask. For a 50L rotary evaporator, the bath can be oil- or water-based and capable of reaching temperatures between 20°C and 180°C.
• Temperature Control: The bath typically includes precise temperature controls, often through a digital interface, to ensure the right temperature is maintained during the evaporation process.

5. Vacuum System

• Vacuum Pump: A high-performance vacuum pump is essential for reducing the pressure inside the system, which lowers the boiling point of the solvent. This enables faster evaporation at lower temperatures.
• Vacuum Control: The system often includes an electronic vacuum controller to adjust and maintain the desired vacuum level, ensuring the solvent evaporates efficiently without overheating or decomposing.

6. Condenser

• Cooling System: The condenser is used to cool the vaporized solvent and convert it back into liquid form. It is typically a large, double-walled condenser with a cooling fluid (such as water or antifreeze) circulating through the outer jacket to maintain a low temperature.
• Design: It includes coil with a double-walled jacket that provides a large surface area for condensation, which is crucial for handling the large volumes in a 50L system.
• Material: The condenser is made of borosilicate glass, like other parts of the unit, to withstand heat and solvent contact.

7. Collection Flask

• Receiver Flask 20l: The condensed solvent is collected in a large 20l receiving flask positioned beneath the condenser. 
• Material: This flask is made from durable borosilicate glass and designed to be easy to detach for solvent transfer or disposal.

8. Rotary Motion

• Rotation Speed: The evaporation flask is rotated at adjustable speeds, ranging from 20 to 100 RPM (rotations per minute), to increase the surface area of the liquid and speed up the evaporation process.
• Motor: The rotary motion is driven by an electric motor, which can be regulated to control the rotation speed.

9. User Interface

• Control Panel: The manual lift rotary evaporator typically features a control panel for regulating the heating bath temperature, vacuum pressure, and rotation speed. This panel allows precise adjustments to ensure optimal operating conditions.
• Safety Features: As with many large-scale laboratory instruments, safety features such as overheat protection, leak detection, and emergency shutdown systems are included to prevent accidents during operation.

Applications

The 50L manual lift rotary evaporator is typically used in large-scale chemical synthesis, solvent recovery, distillation of high-volume liquids, and in industries like pharmaceuticals, food production, and chemical processing. Its large size makes it suitable for pilot-scale production and for applications where high throughput is required.

This combination of features ensures that the 50L manual lift rotary evaporator is an efficient and versatile instrument for handling large volumes while maintaining precise control over the evaporation process.
