Product Overview
The Small Benchtop Rotary Evaporator is a compact, laboratory-scale distillation system engineered for efficient solvent removal, concentration, and sample purification. Designed specifically for space-constrained environments, this series delivers stable rotation performance and reliable vacuum sealing for research institutions, universities, and pharmaceutical R&D facilities.
For international distributors and laboratory equipment suppliers, this benchtop model offers a high-margin, low-maintenance solution to meet the growing global demand for cost-effective, desktop evaporation workflows.
Key Product Features & Distributor Value
Minimal Footprint for Standard Fume Hoods
• Technical Design: Low-profile, ergonomic benchtop architecture with a compact physical footprint(≤500mm width)designed to fit easily inside standard laboratory fume hoods.
• Commercial Value: Lowers the barrier to purchase for educational and startup labs with premium, limited bench space. The lightweight, optimized layout significantly reduces packaging volume, resulting in a low CBM (Cubic Meter) that minimizes your ocean and air freight costs.
Vacuum-Assisted Distillation & Thermal Protection
• Technical Design: Continuous electronic rotation creates a uniform thin liquid film across the inner surface of the borosilicate glass flask, maximizing the active evaporation surface area.
• Commercial Value: Enables lower boiling points under controlled vacuum, protecting temperature-sensitive active pharmaceutical ingredients (APIs), volatile organics, and botanical extracts from thermal degradation or "bumping." Satisfies end-user demands for high throughput and sample integrity.
Industrial-Grade PTFE & Fluorine Rubber Sealing
• Technical Design: Equipped with a dual PTFE (Polytetrafluoroethylene) and double fluorine rubber sealing compound system capable of maintaining a stable, deep vacuum level below 2 mbar.
• Commercial Value: Provides high chemical resistance against harsh organic solvents (e.g., Acetone, Ethanol, Chloroform, and Hexane). This heavy-duty sealing mechanism drastically reduces vacuum leaks, extending component service life and minimizing after-sales warranty/maintenance costs for distributors.
Digital PID Control for Process Repeatability
• Technical Design: Integrated digital control panel featuring real-time monitoring of rotation speeds (20–200 rpm) and PID-controlled fluid bath temperatures with an accuracy of ±1 ∘C.
• Commercial Value: Ensures the strict, standardized batch-to-batch reproducibility required by modern industrial and academic R&D protocols. Driven by a low-vibration brushless motor to maintain a quiet, compliant laboratory working environment.

FAQ
Q: What is the minimum order quantity (MOQ) for wholesale or OEM orders?
A: We offer flexible MOQ options to support your market entry. Standard inventory models have an MOQ of just 1 set. For custom OEM branding, custom voltage setups, or specific packaging designs, please contact our sales team for a formal MOQ quote.
Q: Does the system include the vacuum pump and chiller, or are they sold separately?
A: The standard package includes the core rotary evaporator unit and essential glassware. Because many laboratories already own vacuum systems, they are sold separately; however, we supply pre-configured turnkey bundles that include matching diaphragm vacuum pumps and recirculating chillers to provide your clients with a complete solution.
Q: How do you ensure the safe transit of fragile borosilicate glassware for international shipping?
A: All glass components are protected by heavy-duty, custom-molded foam inserts and packed inside multi-layered, export-grade reinforced cartons. Heavy-duty wooden crate packaging is standard for bulk container shipments to guarantee zero-transit breakage.
