Control & environment

High-voltage power supply

  • Positive high-voltage supply: +30–50 kV, 0–1 mA, with continuous linear voltage adjustment.
  • Local operation and remote PC control and monitoring.
  • Overvoltage, overcurrent, arc and short-circuit protection.
  • A metal enclosure provides electrical shielding; start/stop control, low electromagnetic interference and high noise immunity support laboratory operation.

Dual-channel syringe pump

  • Set the plunger speed independently for each channel to deliver different liquids.
  • Electrical insulation is designed to withstand high electrostatic voltages.
  • Servo motor drive provides precision and thrust for dispensing viscous liquids.
  • Touchscreen control includes real-time parameter logging and data retrieval. Flow range: 0.02–99.9 mL/h; minimum flow setting: 0.01 mL/h.

Touchscreen control

  • Control spinneret and collector motion from a central interface.
  • Adjust liquid delivery and high-voltage settings, including changes during operation.
  • Coordinate component motion and log, retrieve and export process parameters.

Dehumidification

  • A compact compressor dehumidifier supplies a gentle flow of dry air to reduce chamber humidity to approximately 30% RH.
  • An optional upgraded dehumidifier can reduce humidity to 20% RH.

Mist-free humidifier — optional

  • Evaporative humidification regulates chamber humidity within 50–80% RH without mist deposits on the collector.
  • Quiet, energy-efficient operation with antibacterial protection.
  • Dimensions: 214 × 214 × 545 mm.

Infrared heating

  • Temperature control from ambient temperature to 60 °C.
  • Infrared heating provides rapid, uniform heating with precise temperature control.
03

Spinnerets & motion

Interchangeable spinnerets use dedicated insulating mounts and integrated motion control. Options cover single-needle experiments, composite fibers and multiple-needle operation.

Single-needle spinneret

  • Supplied with 100 stainless steel needles in assorted sizes and a dedicated spinneret holder.
  • Accepts standard metal needles.
  • Adjust the spinning angle and the tip-to-collector distance for the experiment.

Low-volume spinneret

  • Electrospinning with as little as 0.5 mL of solution.
  • The syringe connects directly to the needle without tubing, reducing consumption of costly materials.
  • An optional dual-spinneret setup operates two low-volume spinnerets simultaneously.

Coaxial spinneret

  • For use with the dual-channel syringe pump. Includes five sets of inner and outer needles in different sizes.
  • Interchangeable precision needles maintain concentric alignment.
  • Extended needles support a low onset voltage.
  • Also suitable for gas-assisted electrospinning.

Spinneret motion

  • Motorized reciprocating motion along the drum axis improves membrane uniformity.
  • X-axis travel: 400 mm. Scan speed: 1–40 mm/s.
  • Manual Y- and Z-axis positioning with graduated scales.
  • Set or adjust motion on the touchscreen and review the recorded parameters.

Fiber collection

Choose the collector for the required membrane geometry: flat sheets, narrow aligned ribbons or hollow tubes. A flat plate also accommodates substrates that cannot be wrapped around a drum.

Random fibers

Rotating drum collector

  • Collect random or aligned fiber membranes by adjusting drum speed. High-speed rotation promotes fiber alignment.
  • Speed: 1–5000 rpm; accuracy: ±1 rpm.
  • Drum: 300 mm long × 100 mm diameter.
  • Unrolled membrane size: 300 × 314 mm.

Rotating disc collector

  • Collect narrow, highly aligned nanofiber ribbons along the disc edge.
  • Speed: 1–5000 rpm; accuracy: ±1 rpm. Disc diameter: 140 mm.
  • Sharp or flat edge profiles. The sharp edge provides the highest alignment among the collectors shown.
  • Unrolled ribbon length: 439 mm.

High-alignment rotating collector

  • High-speed rotation produces narrow membranes of highly aligned fibers.
  • Speed: 1–5000 rpm; accuracy: ±1 rpm.
  • Collector: 140 mm diameter × 50 mm long.
  • Unrolled membrane size: 439 × 50 mm.

Rotating mandrel collector

  • Mandrel diameters from 1–30 mm; length: 300 mm.
  • Produces hollow tubular membranes in different sizes, including scaffolds for vascular graft research.
  • Nanofiber diameter: 100 nm–1 μm.

Flat plate collector

  • 10 × 10 cm plate made from 316 stainless steel, with an adjustable collection angle.
  • For quick experiments and substrates that cannot wrap around a drum.
  • An X–Y motion stage is available as an option.
