Electrospinning Machine 30kV
Electrospinning Machine 30kV is great for producing nanofibers.
The actual process will vary by the material and chemistry you are working with. But the general procedure is to mix the polymer with a solvent and fill it in a syringe. It is then loaded on a syringe pump. After that, the syringe pump flow rate is adjusted to the desired flow rate and high voltage is applied to the liquid solution. Under the influence of the intense electric fields, polymers are charged and stretched to small diameter fibers. The electrospun fiber strands are then collected on a spindle.
The following are some pictures of electrospun PVP fibers produced on the Electrospinning Machine 30kV. The first picture shown on the left side shows the electrospun fibers on the collector assembly. The second picture on the right is the freestanding sheet of electrospun fibers after it was removed from the collector. Working with high voltage is unpredictable in many ways yet it produces wonderful results.

Safety
Your safety is paramount and rigorous safety practices must be enforced to ensure your safety when working with high voltage.
This power supply produces high voltages and stores energy that is hazardous. Physical contact with the high voltage output may result in life-threatening or fatal injury.
Before you turn on the high voltage power supply, always confirm first that the dial indicators are turned fully in the counter-clockwise direction and confirm the turn counting indicator reads 0.
Visually inspect the high voltage output connector and any high voltage connections for unintended touching or electrical shorts.
Always keep a safe distance from the test equipment and apparatus or system under test.
Do not touch connections unless the high voltage power supply is off and capacitors are completely discharged. Allow five minutes for the high voltage power supply internal capacitors to discharge. Also, make sure the load capacitance is discharged.
Be extra cautious of any high voltage connections that are exposed. Such live terminals should be shielded and barriers must be provided to prevent accidental contact.
Proper grounding is very important. High voltage power supplies must always be grounded. Ensure that a secure ground connection is made between the high voltage power supply and earth ground.
All ungrounded terminals of the test equipment or apparatus under test should be considered as energized.
The work area for the HV power supply should be kept clean. It is important to put away unnecessary parts and components and to keep them far away from the test area.
The general work area around the HV power supply and high voltage connections must be kept dry.
Do not ground yourself or work under wet or damp conditions.
Always consult with your organization’s health and safety expert.
