Coaxial Spinneret Needles

Coaxial Spinneret Needles

Coaxial needle for coaxial electrospinning and 3D printing made with AISI316, totally autoclavable and reusable.


Coaxial spinneret needles are made of two standard needles, used to simultaneously electrospin or 3D print up to two different polymers or proteins.

These coaxial electrospinning needle are generally used in example to create fibers whose core and shell are made of different materials (core-shell structures), to create fiber (using the inner needle) with a shielding gas barrier (using the outed needle) and to create hollow fiber or with drug etc.

Coaxial Spinneret Needles are ideal for research purposes and can be used with the whole SKE Electrospinning range
Detachable assembly, so easy cleaning operations and minimum dead volume.

Fully customizable and assembled upon customer specifications.
