Description of Explosion Proof Rotary Evaporator
Explosion-Proof Rotary Evaporator (Rotovap) – Safe & Efficient Solvent Recovery,designed for Hazardous Environments
Our Explosion-Proof Rotary Evaporator is engineered for labs handling flammable solvents (e.g., ethanol, acetone, ether) or volatile compounds. With Ex-certified components, such as, rotary motor, inverter, lifting motor,etc, it eliminates ignition risks in explosive atmospheres, ensuring compliance with safety standards (Class II, Division 1/2).
No expense has been spared with these evaporators, yet we crush the market on pricing to provide great value at a low cost.
Key Features of Explosion-Proof Rotary Evaporator
1. Safety & Compliance
Ex-Proof System: Frequency-conversion motor & controller (up to EXDIIBT4 standard).
Dual Sealing: PTFE + fluororubber seals ensure high vacuum integrity and solvent purity.
Bumping Prevention Tube: Avoids sample splashing.
2. Precision Control
PID Temperature Controller: ±0.5°C accuracy with steam temperature monitoring.
Water/Oil Dual-Purpose Bath: SS304 heating bath with intelligent temperature control and bottom discharge valve.
Ensures consistent, reproducible results.
3. Efficient Condensation
Vertical Tri-Effect Condenser: Large surface area for high recovery efficiency.
Our rotary evaporator recovers solvents efficiently and fast with two times the surface area for condensing and twice the recovery volume.
4. Continuous Operation
Auto-Shift Valve System: Enables uninterrupted vacuum during discharge (no pressure drop).
Dual Receiving Flasks (50L + 20L): Dual vacuum valves for rapid pressure relief and sample collection.
5. User-Centric Design
Hydraulic Lift: Smooth height adjustment for rotating flask.
Hot Shields (Optional): Prevents operator scalding.
Sample Testing Port: Integrated for in-process checks.
6. Explosion-Proof Upgrades
Customizable electrical, heating, and rotary controls for hazardous environments (,CN Ex or ATEX compliant).

The application of Explosion-Proof Rotary Evaporator:
☑Concentration of solutions;
Gentle removal of volatile solvents under vacuum to concentrate heat-sensitive compounds like pharmaceuticals or natural extracts or increasing protein concentration in buffer without degradation.
☑Reclamation of solvents;
Recover high-purity acetone, ethanol, or DCM from reaction mixtures for reuse, reducing costs and hazardous waste disposal.
☑Separation of chemicals;
Isolate low-boiling solvents or impurities from higher-boiling products in synthetic chemistry or purification workflows efficiently.
☑Vacuum drying of wet solids;
Remove residual solvents/moisture from crystallized products or precipitates under mild heat, preserving compound stability.
☑Essential oil extractor;
Concentrate delicate plant extracts (e.g., lavender, citrus) at low temperatures to preserve volatile aromatics and terpenes.
☑Remove solvent from sample.
Eliminate extraction solvents (e.g., hexane, ether) from environmental, food, or research samples prior to analysis.
