rotary evaporator with optional electric lifting for lab use

Rotary Evaporator

Main Features

1. Premium glass material: All glass components are high-strength 3.3 borosilicate—resistant to heat and chemicals, compatible with a wide range of solvents and acid/base systems.
2. Intelligent temperature control: PID algorithm for precise and stable bath temperature—ideal for delicate sample concentration.
3. High-efficiency condensation & recovery: Dual vertical condenser provides large condensation area—excellent for low-boiling solvents like ether and ethanol.
4. Precision rotary mechanism: Concentric structure ensures smooth operation.
5. Lifting options: R-101VN & R-101LN—sliding/manual assist; R-301—electric lift.
6. Bath safety cover: Prevents scalds and splash hazards.
7. Split heater/main body design: Flexible maintenance.
8. Excellent sealing: PTFE & Viton dual seals—ensures airtight vacuum and resists chemicals.
9. Bottom heating bath: Easy to clean, dry-burn protection included.
10. Adjustable bottle angle: Knob for angle adjustment—adapts to different protocols.
11. Quick-release flask button: Remove flasks easily and safely—no tools required.

Working Principle

• Lower boiling point: Vacuum system reduces pressure—solvents boil at lower temperatures, protecting heat-sensitive compounds.
• Rotary evaporation: Tilted rotating flask forms a thin film—expands evaporation area, increases rate.
• Constant temperature bath: PID-controlled heating—stable, responsive.
• Efficient condensation: Vapors condense rapidly in the condenser—minimizes solvent loss.
• Leak prevention: PTFE sealing maintains vacuum integrity, prevents air/solvent leaks.

Application Areas

1. Organic synthesis: Solvent recovery/concentration post reaction.
2. Natural product extraction: Gentle evaporation for plant actives, essential oils.
3. Pharmaceutical R&D: Distillation/desolvation of intermediates and APIs.
4. Sample pretreatment: Solvent concentration for analytical chemistry.
5. Materials science: Solvent removal in functional materials/polymers.
6. Environmental testing: VOC concentration in sample prep.
