Product Overview
This benchtop rotary evaporator is designed for small-scale solvent distillation, concentration, and recycling. Occupying less than 0.25m2 of bench space, it delivers continuous, repeatable evaporation for chemistry, pharmaceutical, and biotech applications.
For scientific instrument distributors, this product targets the high-volume demand of university teaching labs, R&D startups, and quality control facilities looking for reliable performance without the footprint or budget of industrial-scale systems.
Technical Core Advantages
Space-Saving Benchtop Footprint
• The Reality: Standard laboratory hoods and benches are crowded. This model features an integrated vertical glassware design that fits completely inside standard walk-in fume hoods.
• Commercial Value: Distributors can confidently pitch this unit to academic labs and startups where bench space directly impacts operational costs.
Rotary Film Distillation Technology
• How It Works: The motor rotates the flask continuously, spreading the liquid into a continuous, thin film across the entire inner surface of the GG-17 borosilicate glass.
• The Benefit: This film maximizes the active heat transfer area. Combined with continuous vacuum pressure, it lowers the solvent boiling point, speeds up evaporation rates, and prevents localized overheating (bumping) of thermally sensitive chemical compounds.
Digital Bath and Speed Controls
• Temperature Accuracy: The heating bath supports both water and oil media (Room Temperature to 99 ∘ C for water; up to 180 ∘ C for oil). Built-in PT100 sensors maintain temperature stability within ±1 ∘ C, preventing thermal degradation of delicate biological samples.
• Adjustable Rotation: Control speed ranges from 20 to 200 rpm via a clear digital display, allowing operators to adjust dynamics based on fluid viscosity (e.g., light organic solvents vs. thick botanical oils).
GG-17 Borosilicate Glass & PTFE Sealing
• Chemical Resistance: All vapor-contact components are made from GG-17 (Borosilicate 3.3) glass and pure PTFE (Teflon) seals. This combination withstands aggressive organic solvents, strong acids, and bases without chemical leaching or seal degradation.
• Vacuum Integrity: The vacuum-tight sealing system maintains stable negative pressure during long runs, reducing solvent emissions and ensuring consistent batch-to-batch concentration results.
Multi-Configuration Adaptability for Global Tenders
• Voltage & Plugs: Built to order in 110V/60Hz or 220V/50Hz configurations with regional plug types (US, EU, UK, AU) to match local laboratory electrical standards.
• OEM Support: Direct factory customization includes private labeling, customized exterior colors, and options for manual or automated electronic lifting mechanisms to help distributors meet specific institutional tender requirements.
Main Applications
Organic Synthesis & Chemistry Labs: Routine solvent stripping and reaction mixture concentration.
Pharmaceutical R&D: Active Pharmaceutical Ingredient (API) isolation and small-scale purification.
Natural Product Extraction: Concentration of plant, botanical, and essential oil extracts.
Academic Training: Hands-on undergraduate chemistry demonstrations and lab coursework.
Factory Supply & Logistics Standards
Direct Manufacturer Pricing: Eliminate middleman margins with direct-from-factory wholesale pricing and dedicated engineering support for spare parts replacement.
Pre-Shipment Testing: Every unit undergoes a mandatory 48-hour mechanical runtime test, electrical safety check, and a static vacuum leak test prior to packing.
Reinforced Export Packaging: Glassware is extremely vulnerable during international transit. We pack all glass components inside custom-cut, high-density polyethylene (PE) foam molds, housed within heavy-duty, multi-layer export wooden crates to eliminate transit breakage.
Compliance Certification: Manufactured under ISO 9001 quality management systems. All units carry valid CE certification for smooth customs clearance into regulated markets.

FAQ
Q: What specific solvents can this system process?
A: Thanks to the GG-17 glass and PTFE seals, the system safely processes common laboratory solvents including Ethanol, Methanol, Acetone, Ethyl Acetate, Hexane, and Dichloromethane without damaging the machine.
Q: How do you handle glass breakage during shipping?
A: All glassware is packed in custom-molded foam inside reinforced export wooden boxes. In the rare event of transit damage, we provide free replacement glass components immediately upon receiving a photo of the broken item.
Q: Can this unit run continuously in a commercial lab?
A: Yes. The induction motor is rated for continuous operation. However, for extended high-throughput use, we recommend connecting the unit to a recirculating chiller to maintain efficient condensation rates.
Q: Do you supply matching vacuum pumps and chillers?
A: Yes. We supply turnkey systems. We can match this rotary evaporator with a chemically resistant diaphragm vacuum pump and a low-temperature cooling liquid circulating chiller based on your target solvent's boiling points.
