Electrospinning Unit (Electroris)

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.

Ultrasonic Homogenizer (200W)

ULTRASONIC MIXERS

Ultrasonic Homogenizer (200W)

Ultrasonic homogenizer is a special and unique product which is applicable for laboratory and small scale manufacturing applications

The device is suitable for developing and performing scientific research.

It has 20 kHz working frequency with adjustable power range between 0-200 W.

It operates in pulse mode and total duration of reaction is also adjustable. In addition, it is equipped with thermometer which is for regulating the temperature of the reaction chamber.

How the Ultrasonic Homogenizer Works

The ultrasonic power supply (generator) converts 50/60 Hz voltage to high frequency electrical energy. This alternating voltage is applied to disc-shaped ceramic piezoelectric crystals within the converter, causing them to expand and contract with each change of polarity.

These longitudinal vibrations are amplified by the probe (horn) and transmitted into the liquid as ultrasonic waves consisting of alternate expansions and compressions. The pressure fluctuations pull the liquid molecules apart creating micro-bubbles (cavities), which expand during the negative pressure excursions, and implode violently during the positive excursions.

As the bubbles collapse, millions of shock waves eddies and extremes in pressures and temperatures are generated at the implosion sites. Although this phenomenon, known as cavitation, lasts but a few microseconds, and the amount of energy released by each individual bubble is minimal, the cumulative amount of energy generated is extremely high.

The high shear energy delivered is at maximum near the tip of the probe, and decreases as the distance away from the tip increases.

Compared to mechanical homogenizers, ultrasonic processing is fast and highly reproducible.

Probes are practically self cleaning, and by virtue of their design, account for negligible sample losses. When used with environmentally safe aqueous cleaning solutions, the Homogenizer becomes a powerful cleaning tool, capable of removing the most tenacious contaminants from normally inaccessible locations. Unlike ultrasonic baths, which dissipate the vibrational energy over a large area, the Homogenizer probe focuses the energy to create a concentrated, high intensity cleaning zone.
