Coaxial Single Jet E9


This emitter facilitates the direct process of nanofiber production with a core/mantle structure (aka core-shell nanofibers).

It is a double hollow jet, through the inner portion of which the core solution is dispensed, and the mantle solution follows around it.

The main features:

High spinnability

Component connection using the Luer Lock® system

Compatibility with Hamilton needles

Comes with two Hamilton needles of gauges 15 (outer) and 21 (inner)

The outer diameter (O.D) and inner diameters (I.D) of the needles are:

  • The inner needle is 21 Gauge (0.82 mm O.D. and 0.51 mm I.D.)
  • The outer needle is15 Gauge (1.83 mm O.D and 1.37 mm I.D.)
