cautions

1. Make correct wiring before use. Read the instruction manual carefully.

2. Check and confirm that all wiring is correct before starting the device.

3. Turn on the lighting, temperature and exhaust switches on the control interface to confirm whether the lighting, heating and exhaust systems in the box work properly.

4. Connection and inspection of high voltage power supply. Before use, check whether the high-voltage output line and the nozzle are well connected, and whether the polarity is correct; when using the voltage adjustment button for the first time, turn it counterclockwise to the end, turn on the power supply and turn the adjustment button clockwise to increase the voltage. At this time, the display shows  voltage and current value respectively. 

5. When debugging of the syringe pump, use touch screen to debug whether the syringe pump is running normally.

6. When loading electrospinning solution, use syringe to fill the solution manually.

7. During electrospinning operation, it is strictly forbidden to open the door of the box without cutting off high-voltage DC power supply, or touch the metal needle of the electrospinning spinneret with hands, which may cause damage to human body by high-voltage DC power supply. When high-voltage DC power supply is not cut off due to the needs of electrospinning, the metal needle must be moved with an insulator material.

8. When the electrospinning machine works abnormally, high-voltage DC power supply should be turned off immediately, and should be checked by professional and technical personnel. Normal electrospinning can only be carried out after troubleshooting.

9. When adjusting voltage, slowly adjust it clockwise to the required voltage value. When turning off the power supply, turn the power supply voltage (rotary) button counterclockwise to the end (to the 0 position) and turn it off.

10. When the cabinet door is opened, high-voltage power supply and other equipment should stop working. When replacing the electrospinning liquid for the injection pump in the electrospinning box, high-voltage DC power supply must be turned off first.

11. Before sampling, the discharge rod should be in contact with the collector to impose accumulated electric charge onto the sample. Discharge to the ground to ensure personal safety.

12. This equipment is not suitable for electrospinning strong corrosive solution.
