Product Introduction
The Intelligent Digital Rotary Evaporator is a high-efficiency laboratory distillation system designed for solvent removal, concentration, purification, and recovery. Engineered to meet strict international laboratory standards, this system is widely utilized in chemical, pharmaceutical, biotechnology, and environmental testing facilities.
By replacing traditional manual knobs with a microprocessor-based digital control loop, this platform maintains stable heating temperatures and precise rotation speeds. This ensures high process repeatability across analytical runs while minimizing manual oversight.
For Distributors & OEM/ODM Partners: This standard-compliant platform offers flexible voltage configurations (110V / 220V), regional plug variations, and modular custom branding options designed to meet local regulatory and market entry requirements.

Technical Advantages
Microprocessor Digital Control & Repeatability
Unlike traditional manual units prone to analog dial fluctuations, this system features an advanced digital feedback control loop:
• Direct Readout: Continuous LCD/LED display provides synchronized monitoring of both current RPM and actual bath temperature.
• Process Repeatability: Standardizes evaporation parameters across different laboratory operators and shifts, ensuring consistent SOP execution.
Advanced Film Evaporation & Bumping Control
• Uniform Heat Transfer: Flask rotation creates a continuous, highly thin liquid film across the entire inner flask wall, drastically increasing the active surface area for rapid evaporation.
• Boiling Stability: Microprocessor-regulated speed dynamics prevent sudden rotational jerks or speed spikes, significantly reducing the risk of sample bumping (sudden boiling) and protecting volatile or sensitive compounds.
High-Efficiency Dual-Helix Condenser Design
• Maxim Solvent Recovery: The glass condenser incorporates a dense, multi-turn dual-helix coil that maximizes the vapor-to-coolant contact area, achieving exceptional condensation efficiency and minimizing VOC emissions.
• Process Visibility: The fully transparent heavy-wall glass structure allows laboratory personnel to monitor condensation rates, condensation lines, and flow dynamics in real time.
Premium GG-17 Borosilicate Glass Components
• Chemical Inertness: Exceptional resistance to strong acids, bases, and aggressive organic solvents utilized in routine extractions and chemical synthesis.
• Thermal Shock Resistance: Engineered with a low coefficient of thermal expansion, ensuring structural integrity during rapid thermal transitions between cold solvent vapors and hot bath temperatures.
Dual Hardware Safety Interlocks
• Dry-Heating Cutoff: Automatically cuts off electrical supply to the heating elements if the bath fluid level falls below the minimum threshold, preventing thermal runaway.
• Over-Temperature Protection: A secondary hardware thermal circuit cuts power independently if the bath temperature exceeds the user-defined safe limit.
Key Applications
Pharmaceutical R&D: Active Pharmaceutical Ingredient (API) concentration and solvent removal post-extraction.
Chemical Synthesis: Organic chemistry purification, solvent recycling, and crystallization processes.
Food & Natural Products: Extraction and concentration of essential oils, volatile flavors, and natural bioactive compounds.
Environmental Analysis: Sample concentration prior to chromatographic injection (GC/MS, HPLC).
Factory Quality Management & Validation
Every single unit undergoes rigorous pre-shipment testing at our ISO-certified manufacturing facility to guarantee field reliability:
Dielectric & Insulation Testing: Compulsory high-voltage insulation tests to verify electrical safety compliance with CE directives.
Vacuum Tightness Run: The complete glassware and seal assembly is pressure-tested under deep vacuum over sustained durations to confirm zero leakage.
Thermal Calibration: Dual-point temperature validation of the heating bath against calibrated reference thermometers to ensure PID accuracy.
Commercial & OEM Capabilities
Hardware Localization: Factory-configured 110V/60Hz or 220V/50Hz electrical setups equipped with US, EU, UK, or AU heavy-duty power cords.
OEM/ODM Customization: Silk-screen logo application, custom chassis powder coating colors, customized control panel interfaces, and localized operational manuals.
Service Continuity & Logistics: Backed by a comprehensive 1-year hardware warranty. We guarantee long-term warehouse availability of replacement vacuum seals, critical glass components, and heating elements to minimize downtime.
FAQ
Q: Are the vacuum pump and recirculating chiller included in the standard package?
A: No, the standard equipment package includes the digital rotary evaporator unit, the integrated heating bath, and the complete standard glassware assembly. We supply matching chemical-resistant diaphragm vacuum pumps and digital recirculating chillers as optional auxiliary equipment to build fully integrated, turnkey distillation systems.
Q: What is the standard lead time for bulk distribution or customized OEM orders?
A: Standard neutral units typically ship within 7–15 working days from factory stock. Custom OEM/ODM orders-involving private labeling, specific color configurations, or customized glassware geometries-require a 20–30 day production lead time, depending on the exact order volume and customization scope.
Q: What is the Minimum Order Quantity (MOQ) for custom branding?
A: The MOQ for custom logo application, localized control panels, and custom packaging is 10 units. For standard neutral packaging (no branding modifications), we welcome sample and trial orders starting from 1 unit.
Q: How are the fragile glass components secured against breakage during international transit?
A: All high-borosilicate glass components are nested in thick, high-density pre-molded polyethylene foam (PE) inserts. The entire system is then enclosed within drop-tested, heavy-duty plywood crates. This structural packaging completely eliminates internal movement, ensuring maximum protection during international air freight or ocean container shipping.
