pilot scale rotary evaporator with set speed and temperature

Pilot Scale Rotary Evaporator

Main Features

1. High-performance glassware: Core components (evaporation flask, collection flask, condenser) are made from 3.3 borosilicate glass—excellent thermal shock resistance and chemical stability for acids, alkalis, and organic solvents.
2. LCD operation interface: High-definition display, encoder-based temperature and speed setting—responsive and intuitive for precise control.
3. Three-stage high-efficiency condensing system: Main cooling, sub-cooling, and three-way buffer condenser—significantly boosts recovery efficiency and prevents solvent escape.
4. Intelligent sealing: PTFE + Viton seals—corrosion-resistant, excellent vacuum performance for long-term stable operation.
5. Electric/manual dual lift bath: Liquid level monitoring and dry burn protection—ensures safe, convenient operation.
6. Flange connection: Easy disassembly, cleaning, and fast maintenance.
7. PTFE discharge valve: Corrosion-resistant and durable—suitable for strong acids/alkalis.
8. Lockable casters: Flexible movement and stable installation.

Working Principle

• Decompression lowers boiling point: Vacuum reduces pressure, allowing solvents to boil at lower temperatures—protects heat-sensitive substances.
• Rotary thin film evaporation: Tilted, rotating flask spreads liquid into a thin film—maximizes evaporation rate.
• Constant temperature heating: Bottom-heated bath with dry burn protection/liquid level control—stable, safe heat source.
• Multi-stage condensation: Vapor passes through three condensers and collects in the flask—high recovery, minimal loss.
• Tee buffer: Prevents liquid from directly entering condenser—protects condensation effect and system stability.

Application Areas

1. Chemical development and pilot certification: Solvent recovery, concentration, and refining of intermediates post-reaction.
2. Pharmaceuticals: API concentration and flammable solvent recovery (ethanol, acetone, DMF).
3. Plant extraction/natural products: Solvent removal after volatile oil extraction, mild concentration of heat-sensitive natural substances.
4. Materials science/polymer engineering: Removal of low-boiling by-products in nanomaterials, resin, and monomer synthesis.
5. Environmental/testing labs: Water sample concentration, VOC recovery, hazardous waste pretreatment.
