Doxa Microfluidics is conscious about the struggling of resources of worldwide Companies and Technical Institutes to do their own R&D. Regarding this issue, Doxa Microfluidics`s Staff has worked on a more compact, fresh and smarter machine design that allows lower investment by the hand of our customers, but maintaining the higher quality standards in our components and maintaining the main features too that enables your research team to achieve the top levels in the coaxial electrospinning/electrospraying process design.
Brand new smart concept of Doxa Microfluidics StartUp Electrospinning Machine is a Lab Device adressed for Process Design of Core-Shell Nanofibers and Nanoparticles. Conceived and designed upon our leading research expertise on Electrospinning & Electrospraying Techniques, at a very competitive price, being the best choice to deal with laboratory research, key to success designing novel Coaxial Electrospraying & Electrospinning Processes (core-shell and plain nanofibers and nanoparticles) from a wide range of applications in diverse sectors such as:
Microencapsulation of active substances for controlled protection/release for Food, Pharma, Veterinary, Cosmetics, Tissue Engineering, Chemicals, Catalysts, Security, Sensoring,… Functional Nanofiber-based membranes/sheets/filters: Filtering, Screening, Sieving, Smart Textiles, Footwear and Fabrics.

Coaxial Electrospraying & Electrospinning
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)
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.

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.

- 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.
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.
