Overview
The EYELA N-1300V-W Rotary Evaporator is an engineered solution for efficient, reproducible solvent removal under reduced pressure in research and quality control laboratories. Based on the fundamental principle of rotary evaporation—where reduced pressure lowers the boiling point of solvents while controlled heating and continuous rotation increase surface area and mass transfer—the N-1300V-W delivers consistent performance across diverse sample matrices. Designed and assembled in Shanghai under EYELA’s global quality management system, this model features a vertical dual-layer condenser (0.146 m² effective cooling area), brushless DC motor drive, and integrated manual counterbalance lift mechanism with 180 mm stroke and infinite adjustability. Its compact footprint (543 × 352 × 823 mm) and stainless steel (SUS304) bath construction support long-term durability in demanding environments, including life science applications requiring frequent cleaning and chemical resistance.
Key Features
- Brushless DC Motor Drive: Ensures stable, low-vibration rotation from 10 to 310 rpm with high torque retention at low speeds—critical for viscous or foaming samples.
- Vertical Dual-Layer Condenser: Provides 0.146 m² effective condensing surface area, optimized for rapid vapor capture and high recovery efficiency, especially with low-boiling solvents such as dichloromethane, acetone, or ethyl acetate.
- Manual Counterbalance Lift System: Enables smooth, tool-free vertical positioning of the evaporating flask over a full 180 mm range, supporting ergonomic operation and precise alignment with the condenser.
- Chemically Resistant Sealing System: Employs a dual-material seal (PTFE + Viton) rated for compatibility with common organic solvents, acids, and bases—meeting ASTM D471 requirements for elastomer resistance.
- Precision Temperature Control: Digital PID-controlled water bath maintains setpoint accuracy within ±1 °C across the 10–90 °C operating range, ensuring repeatability in method-driven workflows.
- Modular Flask Mounting: Supports left/right-side installation and programmable forward/reverse rotation (optional timer function), enhancing flexibility during multi-step purification protocols.
Sample Compatibility & Compliance
The N-1300V-W accommodates standard ISO-K tapered glassware (e.g., 3 L round-bottom flasks) and is routinely deployed in life science labs for concentration of protein solutions, nucleic acid extracts, natural product fractions, and synthetic intermediates. Its PTFE/Viton sealing interface complies with USP Class VI biocompatibility testing criteria for extractables, and the SUS304 bath meets ISO 15223-1 labeling requirements for medical device manufacturing environments. While not certified for GMP production use, the instrument supports GLP-compliant documentation when paired with external loggers for temperature and vacuum traceability. It operates safely within ambient conditions of 5–35 °C and relative humidity ≤80% RH non-condensing, per IEC 61010-1:2010 safety standards for laboratory equipment.
Software & Data Management
The N-1300V-W operates via analog/digital hybrid controls: rotation speed is adjusted using a calibrated rotary knob with digital RPM display; bath temperature is set and monitored via LED digital readout. Though it does not include embedded data logging or PC connectivity, its stable analog architecture ensures electromagnetic compatibility (EMC) per EN 61326-1:2013 and facilitates integration into validated systems where external sensors (e.g., vacuum transducers, PT100 probes) feed data into LIMS or ELN platforms. For regulated environments, users may implement manual audit trails aligned with FDA 21 CFR Part 11 principles by recording setpoints, run durations, and observed endpoint conditions in bound lab notebooks or electronic records.
Applications
- Concentration of aqueous and organic extracts in natural product isolation and metabolomics workflows.
- Removal of volatile reaction solvents (e.g., THF, toluene, DMF) following synthesis in medicinal chemistry labs.
- Preparative-scale solvent exchange in polymer characterization and nanomaterial formulation.
- Routine QC sample preparation prior to HPLC, GC-MS, or NMR analysis.
- Lyophilization pre-concentration steps in biopharmaceutical process development.
FAQ
What is the maximum recommended flask size for the N-1300V-W?
The unit is mechanically rated for 3 L round-bottom flasks when equipped with the optional reinforced shaft assembly.
Can the N-1300V-W be used with oil baths?
Yes—when paired with the OSB-2200 oil/water bath (sold separately), the system supports temperature ranges up to 180 °C, though control accuracy degrades to ±3 °C under oil heating per manufacturer specifications.
Is vacuum pump compatibility specified?
The unit features a standard 10 mm outer diameter vacuum port and is compatible with diaphragm pumps capable of reaching ≤400 Pa; ultimate vacuum performance depends on pump capacity, trap efficiency, and system leak integrity.
Does the condenser require chilled water circulation?
Yes—optimal condensation efficiency requires recirculated coolant at 5–15 °C; flow rate should be maintained at ≥1.5 L/min to prevent vapor breakthrough during high-throughput evaporation.
How is maintenance performed on the rotating joint?
The PTFE/Viton seal is field-replaceable using EYELA service kit #N-1300-SEAL; routine inspection every 200 operating hours is recommended to ensure vacuum integrity and rotational smoothness.
