상품상세정보

Lab nanofiber electrospinning machine comprises of a bipolar high voltage supply and a set of collectors for different applications. The instrument also equips with a unique rotary collector through which user will be able to spin the fiber into threads and collect it in spools. The diameter of the fiber depends on various parameters but mainly flow rate. In order to make fiber in to yarn, two syringe pumps, one with positively charged spinneret and the other with negatively charged spinneret, are targeted to a funnel shaped collector from where fiber yarns are formed and rolled into spool.

Lab nanofiber electrospinning machine is a system for producing the ultrafine fiber with the diameter of 20 - 1000 nm. The nanofiber has a high specific surface area, small diameter, and large porosity. There are more than 100 kinds of polymers could be used as raw materials, and also protein, collagen, organics (PEO, DNA, PAA, PLA, nylon, polyester, acryl resin, PVA, PS, PAN, peptide, cellulose).

Lab nanofiber electrospinning machine main features:

1. Cabin Heating: Upto 45°C using 1000 watt coil heater

2. The chamber is provided with Residual Charge Discharge Stick which is used for static removal

3. Safety switch provided to switch off H.V. Power supply when door is opened

4. LED cabin lighting and back light to view Needle tip and electrospin process

5. Exhaust fan is provied for solvent vaporization. It is also used for cooling down the equipment after spin process

6. Emergency stop is provided on the control panel to stop the equipment where there is any emergency

7. Graduation scale provided on the granite surface in X & Y direction which helps the end-user to achieve repetitive results by marketing the positions of syringe pumps, target and rim rotator

8. Software control of various features like mandrel rotating speed, duration, syringe pump flow rate, X, Y stage speed, etc.

9. Rotating mandrel targets of varying diameters, Y-stage target, and stationary plate target are provided with the system.

10. Coaxial spinneret: Our Nano fiber electrospinning unit equips Coaxial spinneret which helps to produce Hollow nanofibers and Core/Sheath nanofibers. This technology can also be used to combine different characteristic of each polymer into one fiber

11. Stand-alone fume hood has features like exhaust fan, halogen lighting, and transparent door for monitoring electrospinning process

12. Built-in arc protection circuit

Lab nanofiber electrospinning machine specifications:

Input Power

•     208~240 VAC single phase (For 110 VAC, please order a 3000W transformer)

•     Max. power consumption: 1500 W

High Voltage Power Supply

•     Digital voltmeter and current meter

•     Electrostatic removal device-discharge stick is integrated to the fume hood

•     Constant current / constant voltage modes available

•     Built-in arc protection circuit. Normally for the electrospinning process, current < 5 μA. Please limit current < 20 μA to avoid high voltage arcing damage

Dual-channel Syringe Pump

•     Dual-channel   syringe pump with independent speed control allows syringes to eject solution   at different rates.

•     Four syringe dispensing systems are included and controlled by the software. (Two   syringes per group at the same pump rate)

Attention: Please use the glass syringes. Due to the safety concerns, do not use the disposal plastic syringes.

Metal Funnel Collector and Yarn Spool

•     Metal funnel collector is a funnel shaped rotating mandrel where fiber yarns are formed and rolled into spool. A thin film web of nanofiber is first formed on a metal funnel collector and is drawn initially to a 3D cone shape. With the rotation of funnel collector, a twisted nanofiber yarn is drawn from the vertex of the cone.
