The RE-201D combines durability, user-friendly controls, and energy efficiency, making it a cost-effective solution for laboratories prioritizing productivity and safety.  

Key Features of the RE-201D 2L Rotary Evaporator

1. High-Quality Construction: The RE-201D features corrosion-resistant borosilicate glass and PTFE seals, ensuring compatibility with aggressive solvents and long-term durability.  

2. Precise Temperature Control: A digital thermostatic water bath (ambient to 99°C) enables precise heating for optimal evaporation rates.  

3. Adjustable Rotation Speed: A 0–120 RPM stepless speed regulator ensures gentle mixing and uniform thin-film formation.  

4. Safety Enhancements: Includes overheat protection, and a splash guard to minimize operational risks. 

5. Efficient Condensation: A large serpentine condenser with high cooling capacity maximizes solvent recovery efficiency.  

6. Compact Design: Space-saving structure with intuitive interfaces for easy integration into busy lab environments.  

Applications of the 2L Rotary Evaporator

The 2L rotary evaporatoris widely used in:  

1. Pharmaceutical R&D: Concentrating active compounds or purifying intermediates.  

2. Chemical Synthesis: Recycling solvents like ethanol or acetone.  

3. Essential Oil Extraction: Isolating volatile compounds from plant materials.  

4. Food & Beverage: Removing residual solvents in flavor or fragrance production.  

5. Academic Labs: Teaching distillation principles or supporting small-scale research.  

Its versatility also extends to environmental testing (e.g., concentrating pollutant samples) and cannabis processing (THC/CBD purification).  

Application Case

A biotech startup used the RE-201D to optimize their cannabinoid isolation process. By adjusting rotation speed (40 RPM) and bath temperature (50°C), they achieved 95% ethanol recovery from 1.5L hemp extracts in under 2 hours. The PTFE seals prevented leakage during vacuum operation (-0.09 MPa). This reduced solvent costs by 30% and accelerated daily production cycles.  

Maintenance Guidelines

1. Daily Cleaning: Wipe glass surfaces with mild detergent; avoid abrasive tools.  

2. Lubrication: Apply silicone grease to PTFE joints monthly to ensure smooth rotation.  

3. Seal Inspection: Check O-rings quarterly for wear; replace if cracks occur.  

4. Bath Care: Drain and descale the water bath every 3 months using citric acid.  

5. Motor Maintenance: Avoid overloading (keep flask volume ≤80% capacity) to extend motor life.  

Store the unit in a dry environment and perform annual professional calibration for optimal accuracy.  

Why Choose the RE-201D?

This 2L rotary evaporator balances affordability and professional-grade performance. With CE certification and a 1-year warranty, it’s a trusted choice for labs seeking reliability. Custom configurations (e.g., explosion-proof motors) are available upon request.

FAQs

1. Why is the evaporation speed slow?

Check vacuum levels and condenser temperature; ensure no blockages in the vapor path.  

2. How to prevent sample bumping?

Reduce bath temperature or rotation speed; use boiling chips if necessary.  

3. What solvents are compatible?

The RE-201D works with most solvents (e.g., DCM, acetone), but avoid hydrofluoric acid or strong alkalis.  

4. How to fix vacuum leaks?

Inspect seals and joints; reapply grease or replace damaged O-rings.  

5. Can it handle viscous samples?

Yes, but reduce rotation speed to 30–50 RPM and increase bath temperature gradually.
