The Importance of Working in an Electrospinning Chamber

When working with high voltages, safety is the number one priority. With the Linari electrospinning hood, your safety is reassured:

  • Automatic high voltage generator cut off system.
  • Overpressure relief trap
  • Grounding of all metal components
  • Plexiglass sliding door
  • 10m3/h ventilation system.

Temperature and humidity are considered very important factors in the control of fibre size and uniformity.

Various studies have investigated and shown the effects of altering temperatures on fibre characteristics and how alterations in the environment may result in issues with reproducibility.

For example, cellulose nanofibers electrospun between 17.5 C and 32.5 C by Hardick et Al showed an average fibre diameter of decrease of 360nm to 284nm. Similar studies on humidity have also shown its effect on fibre size also, however, these behaviours are highly dependent on polymer type. Htike et Al showed that for fibres made of poly(caprolactone) (PCL) and poly(ethylene glycol) (PEG), increasing humidity resulted in increased fibre size, whereas conversely, it was shown by Kim et al that higher humidity resulted in larger diameter fibres when electrospinning with polystyrene. Many studies have shown that reduced humidity also increases beading in fibres, due to solvent drying too fast, causing pulses of fibre jets rather than smooth flow Furthermore, with increasing humidity, there may be the formation of fused or flattened fibres.

For the scientist spinning with various materials or wishing to be able to have tight control over their fibre size, quality and uniformity, it may be necessary to have a more regulated environment for electrospinning.

With Linari’s customisable electrospinning hood, you can take control of your electrospinning process and get the consistent, repeatable results you need. With a built-in RH monitor and heating capabilities up to 50°C, you will have the freedom to modify your electrospinning conditions to suit your needs.

For those working with toxic solvents, we suggest the addition of our activated carbon filter, to remove dangerous solvent vapours.

Spinning in a hood is also important for the extraction of the potentially toxic solvent fumes, as they evaporate off during the electrospinning process.

Electrospinning is a polymer extrusion-based technology, popular for its ability to fabricate ultra-thin fibres of micrometre to nanometre in diameter.
Both beginners and expert researcher have experienced common issues exploring the world of nanofibers.
