Accessories & Materials
Three concentric flow paths for combining three materials in nano- and microfibers. Interchangeable needles let you choose a configuration for the materials and solution viscosities you use.

Enlarge image ↗The three-layer head combines polymer streams with different properties in a concentric structure. For suitable formulations, a more readily spinnable inner material can support a less-spinnable outer material. Needle combinations can be changed to suit the formulation.
Enlarge image ↗The stainless-steel internal assembly can be fully disassembled so each component is accessible for cleaning. The small internal cavity limits the solution retained in the head.

Enlarge image ↗Elongated needles concentrate the electric field at the tip. The inner-to-outer needle-tip height difference is adjustable up to 1.5 mm. The insulating fixture adjusts the spinning angle and height. Standard Luer connections, a high-voltage socket and plug, and concentric needle alignment support setup.
Model dimensions and the general needle-gauge reference are listed separately. Please specify the model and required dimensions when ordering.
