MSK-ESC-R2R Roll to Roll Electrospinning System with Syringe Pump and Heating Vacuum Bed for Uniform Nanofiber Coating
The MSK-ESC-R2R system is engineered for laboratory-scale continuous electrospinning processes, enabling uniform nanofiber deposition on flexible substrates. It integrates an automatic roll to roll substrate feeding and retrieval mechanism, facilitating uninterrupted coating workflows. This setup is ideal for applications requiring precise nanofiber layering with controlled thickness and morphology.
Central to its operation is a digital syringe pump that delivers a consistent flow of polymer solutions, supporting syringe volumes up to 200 mL. The system’s heating vacuum bed, capable of reaching 100°C, aids in solvent evaporation and coating bake-out directly on the substrate. The high voltage power supply offers adjustable output from 0 to 30 kV with a maximum current of 1 mA, ensuring stable electrospinning jets across multiple needles.
Key Features
- Linear array of 5 syringe needles spaced 25 mm apart for uniform coverage up to 160 mm width.
- Automatic roll to roll system with precise speed control, supporting substrate widths up to 200 mm.
- Heatable vacuum bed with PID temperature control up to 100°C for efficient coating drying.
- Digital syringe pump with multiple operating modes and flow rates from 1.963 μL/min to 294.524 mL/min depending on syringe size.
- Single high voltage supply cable minimizes jet repulsion between needles, enhancing coating uniformity.
- Removable spraying heads accommodate various needle gauges (22Ga to 30Ga) for flexible coating parameters.
- High voltage power supply with digital voltage and current display, constant current and voltage modes, and wide AC input range.
