Lab scale Electrospinning unit (Electroris)

Standard and dual pump electrospinning systems

Electroris® is a setup to prepare polymeric/ceramic nanofibers with diameter range of 50 nm to a few microns. Electroris® electrospinning setup mainly consists of main body including syringe pump, spinneret, collector system and high voltage power supply.

Two different types of Electroris® are available: Standard model and dual pump Electrospinning system (Side by Side Electroris). In side by side Electrorspinning system there are two syringe pumps on both side of the rotating collector drum, so there are 2 syringe pumps, 2 scan systems, 2 distance adjuster and 2 High-Voltage Power Supply. Production rate will be two times of standard model, but this is not the main advantage of this models. In these systems two different materials can be electrospun simultaneously. Also we can electrospin polymeric material in one side while additive materials such as medications can electrospray from opposite side. Therefore it is suitable in pharmaceutical, medicine, biology and ... researches. Also it is useful in the manufacture of composite and ceramic nanofibers.

This device employs a panel for controlling of electrospinning parameters including injection rate of polymer solution, working distance, rotating speed of collector drum, working temperature (room temperature to 45°C) and working time. Electroris® supplies sufficient safety scheme for users with respect to the handling of a high voltage power supply and chemical solvents.
