ELECTROSPINNING UNITS

Laboratory Electrospinning Unit (Electroris)

Electrospinning is an established method of producing nano- and micro-fibres from a wide variety of natural and synthetic polymers is knows as Electrospinning

The method used to produce these fibres is as follows:

By introducing a polymer solution at a constant flow rate though a small restriction such as a syringe needle.

A high voltage, typically 10 to 30 kV is connected to the needle; it is the applied voltage that induces a charge on the surface of the liquid droplet, when a critical charge is reached, the physical shape of the droplet surface changes, the hemispherical surface of the fluid elongates and a Taylor cone forms.

By applying a greater voltage the now charged droplet , the charged liquid jet is ejected from the Taylor cone and attracted to the earthed collector, which is positioned at a fixed distance from the needle. During this process the solvent evaporates from the polymer solution, leaving dry polymer fibres on the collector.

Our lab scale electrospinning machine has the ability 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
• Dual pump Electrospinning system (Side by Side Electroris).

In side by side Dual pump Electrospinning system, there are two syringe pumps on both sides of the rotating collector drum;

• 2 syringe pumps,
• 2 scan systems,
• 2 distance adjuster and
• 2 High-Voltage Power Supply.

Production rates will be twice that of the standard model,

Main advantage of this model.

• two different materials can be electrospun simultaneously.
• Electro spin polymeric material in one side with additive materials such as medications can electrospray from opposite side.

With this flexibility in design, our equipment is especially suitable in:

• Pharmaceutical,
• Medicine,
• Biology, bone and Epidermis porosity replication
• Material Science research. Also, it is useful in the manufacture of
• Composite nanofibers.
• Ceramic nanofibers.

Our device controls the 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® supplies sufficient safety scheme for users with respect to the handling of a high voltage power supply and chemical solvents.
