Modular Coaxial Needle Base – AISI 316, Core-Shell
Modular Coaxial Needle Base – AISI 316, Core-Shell
Base of modular coaxial needle to customize your coaxial electrospinning equipment.
The ideal solution for core-shell electrospinning with any type of polymer, even in the most corrosive solvents.
SETUP WITH INTERCHANGEABLE AND DETACHABLE TIPS
All the tips are made of AISI 316 stainless steel and are laser welded for maximum cleanliness and precision. Customized tips can be created upon request with diameters and lengths differing from those listed in this catalog.

BASE SELECTION GUIDE
LAYER 1 BASE – INTERNAL
Suitable with all COAX-N tips. At least the second layer (COAX-L2M) is necessary to complete a coaxial system.
LAYER 2 BASE – INTERMEDIATE
- Layer 1 COAX-N108 → Layer 2 COAX-N218
- Layer 1 COAX-N118 → Layer 2 COAX-N230
At least the first layer (COAX-L1M) is necessary to complete a coaxial system.
LAYER 3 BASE – EXTERNAL
Layer 1 COAX-N108 → Layer 2 COAX-N218 → Layer 3 COAX-N330
The first (COAX-L1M) and second layer (COAX-L2M) are necessary to complete a coaxial system.

FREQUENTLY ASKED QUESTIONS
What do I need for a complete 2-layer modular coaxial needle?
Two bases (Layer 1 internal + Layer 2 intermediate), two tips (e.g. gauge 21 + gauge 15), a dielectric support and a sealing kit. The Modular Coaxial Needle Kit includes everything at a bundle price.
Can I upgrade from 2 to 3 layers later?
Yes — that is the main advantage of the modular system. Add the Layer 3 external base and a gauge 11 tip at any time; the existing components remain in use.
How do the modular bases differ from sealed coaxial needles?
Modular bases accept interchangeable tips and can be disassembled for cleaning and diameter changes, while sealed coaxial needles are welded single pieces — more compact and lower cost, but with fixed geometry.
