explosion-proof pilot scale rotary evaporator

Explosion-Proof Pilot Scale Rotary Evaporator

Main Features

1. High-quality glass: All glass components use 3.3 borosilicate—resistant to heat shock, corrosion, acids, alkalis, and organic solvents.
2. Dual condensing system: Main and sub-condensing three-stage reflux structure—large condensing area for high recovery, minimal solvent loss.
3. Explosion-proof core components: Motor, heater, sensors, and control box are flameproof (Ex marking, Grade Gb, Temp T4, 135°C+)—safe for explosive gas environments.
4. Intuitive control: LCD display with encoder—easy temperature and speed adjustments.
5. Electric/manual dual-mode bath lift: Liquid level sensing and anti-dry burn protection for safe, convenient operation.
6. PTFE drain valve: Corrosion-resistant, non-polluting discharge system.
7. Flange interface: Easy to disassemble, maintain, and clean.
8. Locking brake casters: Freely movable and stable positioning.
9. Reliable sealing: PTFE + Viton double sealing—excellent airtightness, prevents vacuum leaks.

Working Principle

• Reduced pressure distillation: Rotary flask heats and evaporates material; volatile solvents quickly condense and recover for efficient separation/concentration.
• Continuous surface renewal: Rotation enlarges evaporation area, prevents overheating and foam overflow.
• Safe heating: Stable bath heat with liquid level/dry burn protection.
• Three-stage condensation: Main, sub, and buffer bottle ensure full vapor condensation and efficient collection.
• Continuous discharge: PTFE system allows ongoing condensate removal during operation—maximizes efficiency.

Application Areas

1. Fine chemicals: Separation/recovery of volatile solvents (aromatics, ketones, ethers).
2. Pharmaceuticals: Raw material concentration, extract production, solvent recovery.
3. Natural products: Essential oil extraction, low-temp concentration/drying of bioactives.
4. New materials: Polymerization, monomer purification.
5. Pilot platforms: Scale-up/synthetic optimization in academic and industrial labs.
6. Hazardous areas: Suitable for organic solvent recovery and flammable gas environments.
