Spraybase® FAQ


Can you customize my system?

Yes, our system is designed with flexibility in mind. We can personalize your system to meet your research needs. Some examples of customization include high voltage up to 80kV, temperature control of the solution, syringe pumps for viscous solutions, and computer control of two systems. This is not an exhaustive list. If you have enquiries contact our engineers.

What are the dimensions of the Spraybase®?

The dimensions of the Spraybase®  system, including the safety cover, are: 537mm (w) x 519mm (d) x 470mm (h). The dimensions include the cover handles and mounting knobs. The height is measured from the base of the feet.

Will the power source work in my country?

The entire systems works on 85 VAC-265 VAC, single phase, 5 amps, 50/60 Hz, meaning the system will work in the US, Europe and Asia.

What items are not provided with the Spraybase kit? 

The items not provided with the Spraybase®  kit include solutions for electrospraying or electrospinning and a computer to visualise the electrospray/electrospinning fibers.

What is the lead time for delivery?

The lead time for the Spraybase®  kit is 6-8 weeks. For our co-axial and tri-axial needles it is 2-3 weeks


What is a Taylor cone?

A Taylor cone refers to the cone shape of the liquid observed at the tip of a charged emitter, when the potential difference is high enough to overcome the surface tension of the liquid.

What precautions must be taken due to high voltage?

The high voltage required for electrospray are potentially lethal so precautions must be made to limit the available current and to prevent the user from coming into contact with exposed parts. Materials used in the Spraybase®  Platform act as an insulator to prevent buildup of electrical charge. In addition, the Spraybase safety cover acts to limit exposure to the system. Our safety cover allows ventilation through vents at the base and is designed to prevent solvent vapors from building up.


What applications do electrospun fibers have?

Electrospun nanofibers have many applications throughout the sciences. Nanofibers are important in the biomedical field for the generation of organ components, tissue engineering, wound dressing, and medical textile materials, among others. Electrospun fibers also have a growing application as a filtration medium for air and water.

What parameters affect electrospinning fibers?

  • Solution properties (viscosity, conductivity and surface tension): The optimal concentration of a solution, which forms a continuous fiber, must be established.
  • Flow rate: The flow rate must be optimized for each solution to allow a continuous fiber to form. Increasing the flow rate will increase the fiber diameter.
  • Emitter inner diameter: The inner diameter must allow continuous flow of the viscous solution. Increasing the needle inner diameter will increase the fiber diameter.
  • Distance between emitter and collector: An optimal distance must be established in order to allow the fiber to dry in flight. If the collector is too close to the emitter a film rather than a fiber may form.
  • Environmental parameters: Temperature, humidity, and air velocity may affect the fiber flight and drying.

What factors go into producing a specific type of fiber?

The polymer and solvent must be chosen to generate a desired type of nanofiber. The specific concentration of solution, which results in a continuous fiber, must be determined by experimentation. Viscous polymers are good solutions often used for electrospinning.

How are the fibers collected?

Fibers are collected on a grounded collector. A stationary collector dish results in the collection of randomly distributed nanofibers. In order to collect aligned fibers the collector must be rotating, for example a rotating drum, wheel or rod.
