Overview
The Shanghai Yarong RE-6000A Rotary Evaporator is an engineered laboratory system designed for efficient, reproducible solvent removal under reduced pressure. Based on the fundamental principle of rotary evaporation—where simultaneous rotation, vacuum application, and controlled bath heating lower the boiling point of solvents while maximizing surface area and heat transfer—the RE-6000A delivers consistent performance in R&D, QC, and pilot-scale synthesis workflows. Its integrated architecture combines mechanical robustness with process reliability, making it suitable for routine evaporation, concentration, crystallization, and solvent recovery applications across pharmaceutical, chemical, food, and academic laboratories.
Key Features
- 6 L rotating flask and 3 L receiving flask configuration supports medium-to-large batch processing without frequent flask changes.
- Digital speed control (0–150 rpm) ensures precise rotational stability across viscosity ranges, minimizing bumping and foaming during volatile or viscous sample handling.
- Motor-driven vertical lift mechanism provides smooth, shock-free 0–180 mm travel—enabling rapid flask immersion and withdrawal while preserving vacuum integrity and operator safety.
- Double-bottomed stainless steel heating bath incorporates a fully enclosed 1.8 kW heating element for uniform thermal distribution, corrosion resistance, and long-term operational stability.
- Intelligent digital temperature controller maintains setpoint accuracy within ±1 °C from ambient to 99 °C, supporting both gentle low-boiling solvent removal and higher-temperature applications such as dimethylformamide or ethylene glycol recovery.
- PTFE-composite stopcock valve enables continuous feed, discharge, and pressure modulation without breaking vacuum or stopping rotation—critical for multi-step extractions or unattended operation.
- Detachable bath design simplifies cleaning and maintenance; all wetted seals utilize chemically resistant, high-purity PTFE treated via proprietary surface modification to enhance longevity and minimize leaching.
Sample Compatibility & Compliance
The RE-6000A accommodates a broad spectrum of organic solvents (e.g., acetone, dichloromethane, ethanol, hexane), aqueous solutions, and moderately viscous mixtures. Its PTFE-sealed joints and borosilicate glass components meet standard laboratory compatibility requirements per ISO 3585 and ASTM E438 Type I Class A specifications. While not certified to GLP or GMP out-of-the-box, the system’s stable control parameters, repeatable mechanical actuation, and traceable digital readouts support compliance-ready documentation when integrated into validated laboratory workflows. Optional vacuum controllers and temperature data loggers may be added to satisfy 21 CFR Part 11 audit trail requirements.
Software & Data Management
The RE-6000A operates as a stand-alone instrument with local digital interface only—no embedded software or network connectivity. All operational parameters (rotation speed, bath temperature, lift position status) are displayed in real time on front-panel LED indicators. For laboratories requiring electronic recordkeeping, external USB or RS-232 compatible data loggers can be interfaced with the analog outputs (if equipped) or via optional OEM-integrated modules. The unit supports manual SOP execution and is compatible with common lab information management systems (LIMS) through operator-entered batch metadata.
Applications
- Solvent removal from reaction mixtures post-synthesis in medicinal chemistry and process development.
- Concentration of natural product extracts (e.g., plant alkaloids, essential oils) under mild thermal conditions.
- Recovery and recycling of high-purity solvents in quality control labs to reduce consumables cost and environmental impact.
- Preparative-scale dehydration of heat-sensitive biomolecules where precise temperature ramping and vacuum control are critical.
- Removal of residual solvents from polymer solutions prior to film casting or rheological characterization.
FAQ
Is the RE-6000A compatible with aggressive solvents such as concentrated acids or halogenated compounds?
Yes—when used with correctly rated PTFE seals and borosilicate glassware, the system handles most common organic solvents and diluted mineral acids. Extended exposure to hot fuming nitric acid or molten alkali hydroxides is not recommended.
Can the unit be integrated with a central vacuum system?
Yes—the vapor outlet features a standard 24/40 ground joint and optional vacuum hose adapter for connection to centralized or pump-based vacuum sources with appropriate cold traps.
What maintenance intervals are recommended for long-term reliability?
We recommend quarterly inspection of PTFE valves and seals, biannual calibration of the temperature sensor against a NIST-traceable reference, and annual verification of motor drive torque and lift mechanism lubrication.
Does the RE-6000A include safety interlocks for overtemperature or vacuum loss?
It includes overtemperature cutoff at 105 °C and automatic motor shutdown upon vacuum break detection—functions compliant with IEC 61010-1 safety standards for laboratory equipment.
