WEISTRON Electrospinning SystemWEISTRON Electrospinning System


Electrospinning system uses an electrical charge to draw very fine (typically on the micro or nano scale) fibres from a liquid. When a sufficiently high voltage is applied to a liquid droplet, the body of the liquid becomes charged, and electrostatic repulsion counteracts the surface tension and a stream of liquid erupts from the surface, until it is finally deposited on the grounded co
llector. 

 The advantages of WEISTRON Electrospinning system :

  • Continuous processes
  • Cost effective
  • Controllable diameters from few nm to several microns
  • Programmable syringe pumps , independent pump / injection rate control
  • High speed drum / wheel-type collectors
  • Suitable for composite nano-fiber nonwoven fabric, cell culture scaffolds, ... etc..

Details of WEISTRON Electrospinning System :

1. High Voltage Power Supply

     The DC high voltage power supply has an adjustable output voltage in large range with built-in over-current

     protection and short-circuit protection. Input is AC 110 V or 220 V and output voltage can be adjusted. 

2. Syringe PumpSystem

     2-1. Programmable Syringe Pump

              Customer can purchase arbitrary sets of syringe pumps according to their need. Each syringe pump can work

              independently. Users can set the speed of the pump on the embedded control computer.

     2-2. Coaxial Electrospinning

              Coaxial spinneret can produce Hollow nanofibers/microfibers, Core/Sheath nanofibers/microfibers. Using the

              coaxial electrospinning method, different characteristics from each polymer can be combined into one fiber.

     2-3. Multi-needle Spinneret

              Multi-needle spinneret is widely used for mass production electrospinning. Multi-needle spinneret can be

              produced nanofibers as uniaxially aligned arrays.

     2-4. Spinning Nozzle

              The Spinning nozzle can move back and forth continuously to improve the uniformity of fiber sheet.

3.  Collector             

      3-1. Plate Collector

               The plate collector is normally used for electrospinning at a moderate production rate.

      3-2. Drum & Wheel-type Collectors (with Speed Indication)

               Drum or Wheel-type collectors of electrospinning are used for collecting aligned nanofiber sheet. This is the

               simplest & effective method to make aligned nanofibers. By using different length/ diameter ratio, with            

              different rotating speed, fiber sheets or aligned fibers can be made.
