This instrument is used to produce electrospun nano-scaffolds for tissue engineering. This instrument has two pumps and four distinct syringes to spin up to four different polymers from two directions. It can conduct the spinning of a polymer from 10 separate nozzles to reduce the time of synthesis. Another feature of this instrument is the scanning movement of the collector that allows customized scaffold widths. The electro-spinning parameters can be programmed for the synthesis of different scaffolds (non-woven, parallel, compound, bead on string, etc). This instrument has a high user safety.
