Best-in-class Electrospinning, TL-Ultra

Product Detail





Electrospinning Machine, TL-ULTRA technical data sheet:

1. Two High voltage power supply devices:

 1st, 0~30KV, digital display, over-current & over-voltage protection. Output power<25W.

 2nd, -20KV ~0, digital display, over-current & over-voltage protection.

 

Negative high voltage automatic compensation function:

By setting the time interval and the compensation voltage, the weakening effect of the insulation of the spinning film on the electric field is compensated, and the electric field is kept constant.

 

2. Four-channel pumps: Totally 4 channels, each channel can be controlled independently for individual syringe.  Pump rate: 0.02ml/h~99.99ml/h ±0.01ml/h 10ml20ml syringes can be used.

Designed for high-voltage electrospinning, the injection thrust is 3-5 times that of ordinary medical syringe pumps, and can be used for high-viscosity liquids. At the same time, a specially designed insulation system separates the power part of the micropump from the syringe loaded with high-pressure liquid, which is suitable for transmitting various liquids for electrospinning. Easy to use, digital display. Flow rate, injection volume, and injection time can all be precisely controlled. The 4 channels can be controlled independently to set different propulsion speeds. It can be used with various syringes of different specifications.

 

3. Drum collector(1-5000rpm), 1 set.

 

Drum 1: D=100mm, L=300mm

Drum 2: D=140mm, L=50mm for collecting highly aligned nano fiber sheet.

Mandrels: D=234568mm, L=300mm

Grooved Drum: D=110mm

Disk collector: D=140mm

 

4. Plate collector with holder150mm*150mm, 1pc.

   

5. Continuous collector roll to roll collector, Films of about 20-100 meters can be collected continuously. ( Can be changed to other collectors if needed. )

 

6. Spinnerets with various insulating holders. the spinnerets can be adjusted up and down, left and right, front and back, and the spray angle can be adjusted freely.

 

6.1 Single-needle spinneret with holder, Can be replaced with needles of different diameters. The equipment contains 100 needles of various diameters.  

6.2 Coaxial spinneret with holder

©  Equipped with 5 sets of inner and outer needles of different sizes.

©  Both inner and outer needles can be replaced.

©  The special needle ensures that the inside and outside are highly concentric.

©  2~3 times longer than common coaxial nozzles on the market, the required spinning voltage is low, and the process parameters are easy to control.

©  It can be used as a special nozzle for microspheres.

©  It can be used as an air flow assist nozzle.

 

6.3 Microsphere spinneret: A kind of coaxial spinneret

6.4 Side by side nozzle

6.5 V-shape spinneret: 4 needles. V-shaped four- needle system, which improves the output and achieves the highest uniformity of film formation. Two sets of double needles are located on both sides of the drum , which can form a film evenly.

6.6 Two tubeless spinnerets, for small amount solution. 0.5ml solution can be used for electrospinning experiments . No consumption of consumables, and it is environmentally friendly.

6.7 Micro-sized spinneret: 1-45 micron, which can spin superfine fibers. Or can be used for near field direct writing.

6.8 Triaxial spinneret with holder, 5-sets of changeable needles.

6.9 Multi-channel spinneret with holder, both 3 channels and 4 channels. With 5 sets of changeable needles.

 

7. Light source: Special designed light source, LED, cold light source, very useful for observing the spinning process by naked eyes.

 

8. Exhaust fan.

This device is equipped to cool down the equipment in working process, and help the solvent vaporization.

 

9. Environmental control system.

9.1 Dust-free Heater. It is placed on the top outside of the chamber. Heated by visible light, which makes the heating more uniform and keeps the chamber clean.

9.2 Dehumidifier: insert dry air to control the humidity inside the chamber. The dehumidifier can quickly reduce the humidity inside the chamber to about 30%, and the wind speed is stable and adjustable.

9.3 Install 3 temperature and humidity meters to display the temperature and humidity online in real time, and at the same time display the highest and lowest values within 24 hours.

 

10. Safety Measures:

10.1. Emergency stop button.

10.2. Door open power cut-off device. When the equipment is running, once the chamber door is opened, the high-voltage system will be automatically powered off, and other power supply systems will still work normally.

10.3. Static elimination device.

10.4. Earthing system. Multi-point grounding ensures the safety of the experiment process.

10.5. Photography mode. When the machine door is closed to shoot the spinning process, good results cannot be obtained due to the reflection of the window. Select the photography mode, you can still spin when the machine door is open, and take photos of the spinning process.

 

11. Slide unit for spinneret: Remote control, digital display. Back & forth moving distance: 400mm, Moving Speed: 1 ~ 15 mm/s
