Dual Pump Electrospinning Machine (Side by Side Electroris®)
Electroris® is a lab-scale electrospinning machine to prepare polymeric/carbon/ceramic
nanofibers with diameter range of 50 nm to a few microns. The machine mainly consists
of metallic body, syringe pump, spinneret system, collector system and high voltage
power supply.
Two different types of Electroris® are available: Standard and dual pump model (Side
by Side Electroris®).
In side by side Electrospinning system, there are two syringe pumps on both sides
of the rotating collector drum, making the system to consist of 2 syringe pumps,
2 scan systems, 2 distance adjusters and 2 high voltage power supplies. Even though
the production rate of dual pump model is two times higher compared to the standard
one, this is not its main advantage. In these systems two different materials could
be electrospun simultaneously. Furthermore, the system makes it possible to electrospin
polymeric material from one side and additive materials, such as medications, from
the opposite side, producing composite nanofibers containing desired components.
Therefore, it is suitable for pharmaceutical, medicinal, biological, etc. applications.
This machine employs a panel for controlling electrospinning parameters including
injection rate of polymeric solution, electrospinning distance, rotating speed of
collector drum, working temperature (room temperature to 45°C) and working time.
Electroris® provides excellent safety schemes for the users with respect to the
handling of high voltage power supply and chemical solvents.
