Spinneret linear motion device to achieve greater static or rotating surface coverage. It is used to electrospin large planar formats (for example, A4 size or bigger) or long cylinders. Ideal for scaling-up application and small medium scale of manufacturing requirements. Fully compatible with our E-fiber platform and our rotating collector. Easy keypad and LCD based user interface. Entirely made in plastic, in order to guarantee no interferences with electrical field and electrospinning process. Electronic feedback for a precise control over speed rotation, in order to guarantee highly reproducible batch-to-batch conditions.
