Detailed Features
SS Flat Collector and a Coaxial Spinneret
A SS Flat Collector (200mmx200mm) and a Coaxial Spinneret are supplied to operate in coaxial electrospinning mode. Different nozzle diameter sizes are available (ID & OD, mm):
– COAXIAL I: 0,9/0,6 & 1,7/1,4 (AISI 304) (by default)
– COAXIAL II: 0,9/0,6 & 1,7/1,4 (AISI 316)
– COAXIAL III: 0,7/0,4 & 1,4/1,1 (AISI 304)
– COAXIAL IV: 1,7/1,4 & 2,8/2,2 (AISI 304)
If you want to design processes where core-shell structures are required you must have the coaxial spinneret.
Double Polarization
The charged nanoparticles produced by electrospinning & electrospraying may “escape” from the electric field during its travel from the emitter to the collector. Doxa Microfluidics StartUp Electrospinning Machine offers double polarized setup (two power supplies +30kV/-30 kV) to eliminate nanoparticle “fly out” and to improve electrospinning & electrospraying performance. The voltages are fully controlled from two knobs, located at the control and visualization zone, which provide the user with a more accurate control of the process.
The charged nanostructures produced by electrospinning & electrospraying may “escape” from the electric field during its travel from the emitter to the collector if the collector is not polarized. The double polarization eliminates nanoparticle “fly out” (and hence avoiding surface dirty) and improves the collection process.
Flow Rate Control
Two Syringe Pump based liquid infusion systems for coaxial electrospinning & electrospraying, driven by stepper motors, allowing a high resolution control of the flow rate through the coaxial nozzle. Syringes from 1 to 30 mL can be used. Then, the flow rate can be varied from 14 µL/h to 3000 mL/h. Steady flow is required to obtain high quality nanoparticles. Microstepping pumps allow precise flow rate control over a wide operation range. Syringes can be used as polymer reservoirs, allowing optimal flexibility and reducing time in changing polymer samples.

Real-Time Visualization
The Taylor Cone is at the heart of Electro-Hydrodynamics atomization. In order to get a steady coaxial/simple electrospinning/electrospraying process, Taylor cone steadiness is required. TAYLOR-CONE visualization is key for checking time-real he performance of the process. Includes: Analog CCD Camera, Lens & Extensor, Camera Support, LED Illumination and VGA output to connect to most of commercial screens.

Security
- The only input required to operate the machine is electricity.
- LED Illumination.
- The unit is equipped with all the security measures, ensuring a safe operation for the user. The machine has two operation modes: safe and normal. In safe mode, the high voltage will turn off and the movable parts will stop at the time the doors are opened, to ensure the security of the user. In normal mode, although the doors are opened all the parts will be kept in operation.
- However, the user will be warned about the risk by a flashing red beacon.
- It also has emergency stop button that will automatically shut down the machine in case of alert.
- In additon, the machine includes Integrated Extractor Hood. The machine includes a fume hood exhaust fan that allows an efficient ventilation of the cabinet.
Touch Panel Control
A 5,7’’ Touch Screen, located on the control and visualization zone, allows the user controlling all the features provided with the machine. The software includes an user friendly interface with the option of sleep-off mode (timer). From this screen parameters such as voltage, illumination, fan extractor.
Enclosure
The unit has been designed to work in a laboratory and research environment, having and excellent flexibility, ease of use and minimum setup time and maintenance. The working area is 650mm x 400mm x 645mm. The transparent enclosure allows the visualization of the process and an easy access to the cabinet.

Climate Control Unit
An additional external unit will enable to control the relative humidity and temperature inside of the cabinet. Relative humidity can be modified between 10% and 80% (±5%) and temperature between room temperature and 45ºC (±1ºC). The envelope (walls and glasses) are thermally insulated to ensure that no condensation take place inside of cabinet.
Why is important?
Some combination of polymers and solvents show different behavior and it is quite sensitive to changes in relative humidity and temperature. The climate control unit provides an accurate control on the basic environmental conditions inside of the cabinet
