Overview
The Shanghai Yarong SY-5000A Rotary Evaporator is a precision-engineered benchtop purification system designed for efficient solvent removal, concentration, and recovery under reduced pressure. It operates on the fundamental principle of rotary evaporation—rotating a sample-containing flask in a heated water or oil bath while applying controlled vacuum to lower the boiling point of solvents, thereby enabling gentle, rapid, and reproducible evaporation without thermal degradation. Engineered for laboratory environments requiring flexibility across diverse sample matrices, the SY-5000A integrates robust mechanical design with digital process control, supporting routine applications in pharmaceutical R&D, fine chemical synthesis, natural product isolation, and academic research laboratories.
Key Features
- Wide-capacity adaptability: Accommodates standard ground-glass evaporation flasks from 50 mL to 5000 mL, facilitating scalability from analytical-scale optimization to pilot-level batch processing.
- Integrated vacuum management: Built-in vacuum controller enables precise setpoint adjustment between −0.01 MPa and −0.095 MPa, with calibration accuracy maintained at ±0.2–0.5% of full scale—critical for consistent boiling point depression and vapor pressure control.
- Bidirectional rotation: Motor-driven rotation supports both clockwise and counterclockwise modes (user-selectable), improving film uniformity on flask walls and minimizing bumping or foaming during volatile or viscous sample handling.
- Dual-mode heating system: PID-regulated temperature control delivers stable thermal output across water and oil bath configurations; digital LED readout ensures traceable, real-time monitoring with ±1 °C stability in aqueous media and ±2 °C in high-temperature oil baths up to 180 °C.
- High-efficiency condensation: Ground-glass dual-path reflux condenser provides 0.18 m² effective cooling surface area, optimized for rapid phase transition of vapors across common organic solvents (e.g., acetone, ethanol, ethyl acetate, dichloromethane) and moderate-boiling-point compounds.
- Intuitive human-machine interface: Full-color touch-sensitive LCD panel displays simultaneous real-time values for temperature, rotation speed, vacuum level, and programmable countdown timer—enabling unattended operation with configurable start/stop logic.
Sample Compatibility & Compliance
The SY-5000A is compatible with a broad spectrum of thermally sensitive and chemically diverse samples, including but not limited to small-molecule APIs, peptide intermediates, plant extracts, polymer solutions, and catalyst slurries. Its ground-glass joints (standard ISO 297/ISO 4790 taper interfaces) ensure leak-tight vacuum integrity and interchangeability with globally sourced glassware. While not certified to IEC 61010-1 or CE for standalone regulatory submission, the instrument conforms to general electrical safety practices for laboratory equipment. Users implementing this system in GLP or GMP workflows may configure operational parameters—including time-stamped temperature/vacuum logs via external data acquisition—to support audit readiness per FDA 21 CFR Part 11 requirements when paired with compliant software infrastructure.
Software & Data Management
The SY-5000A operates as a stand-alone hardware platform with no proprietary software dependency. All process parameters are locally stored in non-volatile memory and displayed in real time on the integrated LCD. For laboratories requiring electronic record retention, analog voltage outputs (0–5 V or 4–20 mA) are available upon request for integration with SCADA systems, LIMS, or custom LabVIEW-based logging platforms. Time-stamped parameter snapshots can be manually recorded or externally captured using USB-connected data loggers—supporting traceability frameworks aligned with ISO/IEC 17025 documentation standards.
Applications
- Solvent removal and concentration of reaction mixtures in synthetic organic chemistry
- Recovery and recycling of high-purity solvents in continuous manufacturing processes
- Lyophilization pre-concentration steps prior to freeze-drying
- Purification of heat-labile natural products (e.g., terpenoids, alkaloids) from botanical extracts
- Removal of residual solvents from polymer films and nanomaterial dispersions
- Batch-wise dehydration of aqueous emulsions in food science and cosmetic formulation development
FAQ
What types of heating baths are supported?
The SY-5000A is compatible with both water and oil baths; temperature stability specifications differ accordingly (±1 °C for water, ±2 °C for oil).
Can the vacuum controller be calibrated onsite?
Yes—the built-in vacuum sensor allows user-accessible zero-point and span calibration using a certified reference manometer.
Is the condenser compatible with dry ice/acetone cooling?
The dual-path ground-glass condenser supports external coolant circulation; direct dry ice/acetone immersion is not recommended due to thermal shock risk to borosilicate glass.
What maintenance intervals are recommended for long-term reliability?
Vacuum pump oil replacement every 200 operating hours, condenser cleaning after each solvent class change, and annual verification of temperature sensor drift against NIST-traceable standards.
Does the unit meet RoHS or REACH substance restrictions?
All structural materials comply with EU Directive 2011/65/EU (RoHS II); material declarations are available upon formal request to the manufacturer.
