Enlarge image ↗The elongated needle design supports electrospinning at lower operating voltages. Concentric inner and outer needles keep the two material streams aligned. The needle-tip length difference is adjustable up to 1.5 mm.
Enlarge image ↗Inner and outer needles can be replaced independently. Select a combination for the viscosity of each solution, or request custom dimensions. The assembly comes apart for cleaning and is designed to use a small quantity of solution.
The spinneret uses stainless-steel and polypropylene Luer lock connectors with PTFE tubing. An insulating holder allows adjustment of the spinning angle and height.
The following inner/outer needle combinations are listed for this spinneret. Custom specifications and dimensions are also available.
