The Explosion-proof Rotary Evaporator ExRE series represents specialized solvent removal equipment designed for hazardous environment applications where flammable vapors may be present. These systems utilize controlled rotation and vacuum-assisted evaporation to concentrate samples while maintaining safety standards required in potentially explosive atmospheres. The series offers three capacity configurations (ExRE-1002, ExRE-2002, ExRE-5003) with rotary bottle volumes from 10L to 50L and corresponding collecting bottle capacities from 5L to 20L.
Operating at temperatures up to 180°C with ±1°C accuracy and rotation speeds from 0-120 rpm, these evaporators provide controlled solvent removal for applications requiring both precision and explosion-proof certification. The systems feature variable heating power options (3KW, 5KW, 8KW) and achieve vacuum levels of -0.095 MPa, enabling efficient concentration of heat-sensitive compounds in safety-critical laboratory and industrial environments.
How It Works
Rotary evaporation operates on the principle of reducing solvent boiling point through vacuum application while maintaining controlled temperature and surface area enhancement via flask rotation. The sample flask rotates continuously at speeds up to 120 rpm, creating a thin film of liquid across the flask walls that maximizes surface area exposure. This increased surface area, combined with reduced pressure (-0.095 MPa vacuum), allows solvents to evaporate at temperatures well below their atmospheric boiling points.
The explosion-proof design incorporates specialized electrical components and enclosures that prevent ignition sources from contacting potentially explosive vapor-air mixtures. Temperature control systems maintain precise heating (±1°C accuracy) while rotation mechanisms ensure uniform heat distribution. Evaporated solvents condense in the collecting bottle through a cooled condenser system, enabling solvent recovery and sample concentration.
The three-model series accommodates different processing scales through variable rotary bottle sizes (10L, 20L, 50L) and corresponding collecting bottles (5L, 10L, 20L), with heating power scaling from 3KW to 8KW to match thermal requirements for different volumes.

Practical Tips
Verify explosion-proof electrical connections remain intact before each use and never operate with damaged enclosures or missing certification labels.
Why: Compromised explosion-proof integrity can create ignition sources in hazardous vapor environments.
Calibrate temperature controller monthly using certified thermometer to maintain ±1°C specification accuracy.
Why: Temperature drift can affect evaporation efficiency and potentially damage heat-sensitive samples.
Schedule annual inspection by certified technician to verify explosion-proof rating compliance and electrical system integrity.
Why: Safety certifications require professional maintenance to preserve hazardous location operating permits.
Match heating power selection to bottle capacity and adjust rotation speed gradually to optimize thin film formation without splashing.
Why: Proper parameter matching maximizes evaporation efficiency while preventing sample loss through violent boiling.
Use appropriate vapor traps between evaporator and vacuum pump to prevent solvent damage to pump components.
Why: Organic solvent vapors can damage pump oil and internal components, leading to vacuum loss and costly repairs.
If vacuum levels drop below -0.095 MPa, check ground glass joint sealing and vacuum line connections before assuming pump failure.
Why: Most vacuum problems result from air leaks rather than pump malfunction, and joint resealing is much faster than pump service.
Record rotation speed, temperature, and vacuum level for each run to establish reproducible processing conditions.
Why: Consistent operating parameters are essential for reproducible evaporation times and sample recovery rates.

Background reading relevant to this product:
What explosion-proof certifications does this equipment carry?
Consult product datasheet for specific explosion-proof certifications. The equipment is designed for hazardous location use where flammable vapors may be present.
How do I select the appropriate model for my processing volume?
Choose based on sample volume: ExRE-1002 (10L rotary/5L collection), ExRE-2002 (20L rotary/10L collection), or ExRE-5003 (50L rotary/20L collection). Consider both initial sample volume and expected concentration ratio.
What maintenance is required for explosion-proof components?
Explosion-proof equipment requires certified technician maintenance to preserve safety ratings. Regular inspection of electrical enclosures, seals, and certification labels is essential for compliance.
Can the heating power be adjusted for different solvents?
Models feature fixed heating power (3KW, 5KW, or 8KW depending on capacity) with variable temperature control up to 180°C. Power selection should match bottle size and typical solvent requirements.
What vacuum pump specifications are required?
System requires vacuum pump capable of achieving -0.095 MPa. Pump must be compatible with organic solvents and include appropriate vapor traps for protection.
How does rotation speed affect evaporation efficiency?
Higher rotation speeds (up to 120 rpm) increase surface area and heat transfer but may cause splashing. Optimize speed based on sample viscosity and volume for maximum efficiency without sample loss.
What are the power supply options for different regions?
Standard configuration uses AC220V 50/60Hz; optional AC110V 60Hz is available. Specify power requirements when ordering to match local electrical infrastructure.
How does this compare to standard rotary evaporators?
Explosion-proof design enables safe use with flammable solvents in hazardous environments but typically requires higher initial investment and specialized maintenance compared to standard laboratory rotary evaporators.
