Overview
The Yunfan YF-01-R Melt Electrospinning Spinner is a benchtop-scale, non-solution-based fiber fabrication system engineered for controlled production of thermoplastic microfibers via melt electrospinning—a process that eliminates solvent handling while enabling direct polymer melt extrusion under high-voltage electric fields. Unlike conventional solution electrospinning, the YF-01-R operates without volatile organic solvents, making it suitable for labs requiring intrinsically safer material processing, reduced environmental footprint, and compatibility with heat-stable polymers such as polypropylene (PP), polylactic acid (PLA), polyethylene (PE), and thermoplastic polyurethane (TPU). The system leverages a precision syringe-driven melt delivery module, temperature-regulated nozzle assembly (operable up to 300 °C), and adjustable high-voltage DC power supply (0–30 kV) to achieve stable Taylor cone formation and continuous fiber deposition onto grounded collectors. Its design adheres to fundamental electrohydrodynamic principles governing melt jet initiation, stretching, and solidification—enabling reproducible fiber morphologies with diameters ranging from 25.55 µm to 180 µm, as verified by SEM imaging and calibrated optical microscopy.
Key Features
- Integrated melt extrusion unit with PID-controlled heating zone (ambient to 300 °C, ±0.5 °C stability)
- Adjustable high-voltage DC power supply (0–30 kV, 0.1 kV resolution, current-limited output)
- Modular collector platform accommodating rotating drums, static plates, or custom substrates
- Real-time monitoring interface displaying nozzle temperature, applied voltage, and extrusion rate
- Compact footprint (W×D×H: 450 × 400 × 520 mm) optimized for standard fume hood integration
- Tool-free nozzle assembly design supporting rapid cleaning and interchangeable die geometries (e.g., single-orifice, multi-orifice)
Sample Compatibility & Compliance
The YF-01-R supports a broad spectrum of melt-processable thermoplastics—including but not limited to polyolefins, aliphatic polyesters, and engineering thermoplastics—with melt flow indices (MFI) between 2–50 g/10 min (ASTM D1238, 230 °C/2.16 kg). It complies with IEC 61000-6-3 (EMC emission standards) and IEC 61010-1 (safety requirements for laboratory equipment). While not certified for GMP manufacturing environments, its operational parameters are fully documentable and support GLP-aligned experimental workflows. All thermal and electrical subsystems incorporate redundant safety interlocks, including overtemperature cutoff, ground-fault detection, and HV discharge delay timers—ensuring operator protection per ISO 13857 and UL 61010-1 guidelines.
Software & Data Management
The YF-01-R operates via embedded firmware with local parameter logging (CSV export via USB port). No proprietary cloud platform or remote control software is included; however, all operational settings—including temperature setpoints, voltage profiles, and dwell times—are timestamped and stored in non-volatile memory for traceability. Users may integrate the device into broader lab data ecosystems via analog output signals (0–10 V for temperature, 0–5 V for voltage feedback) compatible with third-party DAQ systems (e.g., National Instruments, LabVIEW). Audit trails meet minimum requirements for internal method validation and preliminary regulatory documentation under FDA 21 CFR Part 11 when paired with institutional electronic lab notebook (ELN) systems supporting user authentication and version control.
Applications
- R&D of solvent-free filtration media for HVAC and industrial particulate capture

- Education and training in electrohydrodynamics, polymer processing, and advanced fibrous materials science
FAQ
Does the YF-01-R require solvent handling or fume extraction?
No. As a melt-based system, it processes pure polymer granules or pellets without solvents—eliminating VOC emissions and the need for dedicated chemical fume hoods.
Can the system produce sub-micron fibers?
Not routinely. The YF-01-R is optimized for microscale fiber generation (25.55–180 µm), consistent with melt electrospinning’s inherent limitations in jet thinning. Submicron fibers typically require solution-based electrospinning or hybrid approaches.
Is technical support available outside mainland China?
Yes. Yunfan authorizes regional distributors in Southeast Asia, Europe, and North America who provide installation assistance, application guidance, and hardware-level troubleshooting in English.
What maintenance is required for long-term reliability?
Routine maintenance includes nozzle purge cycles after each polymer change, periodic calibration of thermocouple inputs, and inspection of HV cable insulation integrity—procedures detailed in the bilingual (English/Chinese) operation manual supplied with each unit.
