Dip-Electrospinning unit (Electroris-Dip)

Pilot-scale Electrospinning machine

 Electroris-Dip is a polymeric/ceramic nanofibers producer machine in large scale. The conventional electrospinning devices often use a nozzle to produce nanofibers with a very low production rate and it is suitable for research. Despite of the enormous application potential, needle electrospun nanofibers meet difficulties in broad applications in practice, due to the lack of an economic and efficient way to scale up the electrospinning process. Dip electrospinning appeared as an alternative electrospinning technology with the aim of producing nanofibers on a large scale from a compact space. Dip-electrospinning is featured as electrospinning of nanofibers directly from an open liquid surface. Numerous jets are formed simultaneously from the needleless fiber generator. Electroris-Dip has a main body with a stain-less steel drum dipped in a polymer solution bath, a plate / rotating drum collector, positive and negative high voltage power suppliers and a rolling system of substrate.

Electroris-Dip can control the electrospinning parameters and conditions including electrospinner drum and collector rotating speed, working distance, rolling system including the direction and rate, working temperature (room temperature to 45C) and operation time. Electroris-Dip has sufficient safety for users with respect to the handling of a high voltage power supply and chemical solvents.
