Electrical insulation for your syringe pump, to safely apply high voltage up to 35 kV to the solution. HIGH-TENSION INSULATION To apply tension up to 35 kV to your pump, this syringe insulation is strongly recommended. For best performance, connect the pump to a needle on a dielectric support, using PVC tubes. Standard dimensions are sized for the 10 mL glass syringe; contact us for different sizes. Syringe pump and syringes are not included. COMPATIBILITY Suitable for the single-channel syringe pump (BI-SEP-P300) and the remote-control syringe pump (BI-SEP-P1000). FREQUENTLY ASKED QUESTIONS Do I really need syringe insulation? Whenever you apply the high voltage to the solution (rather than only to the collector) above ~25 kV: without insulation the voltage can track back to the pump electronics. Below 25 kV it is often optional; above it, strongly recommended. Does it fit any syringe? The standard version is sized for the 10 mL glass syringe. For other volumes, contact us with your syringe dimensions and we will advise.
Wire drum collector designed to produce very thin, easy-to-peel nanofiber mats. MINIMAL CONTACT POINTS FOR EASY FIBER RELEASE The wire construction minimizes the contact points between fibers and drum. With few contact points you can easily peel your nanofiber mats, even at very low thickness where a solid drum would make the delicate fibers stick and tear. Made of high-resistance hollow aluminum, weight and moment of inertia are reduced to the minimum, allowing high rotation speeds without triggering dangerous vibrations — so you also get aligned fibers along the wire direction. SPECIFICATIONS - Outer wire diameter: 80 mm - Grip diameter: 10 mm - Wire length: 120 mm - Wire diameter: 3 mm - Number of wires: 12 COMPATIBILITY Compatible with our Easy Drum rotary system. FREQUENTLY ASKED QUESTIONS When should I use a wire drum instead of a solid drum? Choose the wire drum when your nanofiber mat is very thin and delicate: the reduced contact area lets you peel it off intact. A solid aluminum drum is better for thicker mats and continuous surfaces. Does the wire drum align the fibers? Yes — at high rotation speed the fibers align along the wires, and the gaps between wires enhance alignment compared with a full surface.

The two solutions were fed through plastic tubing from separate syringe pumps into a coaxial needle (Linari Engineering, Pisa, Italy) at controlled flow rates - the core-shell configuration that allows one material to be enclosed within another during spinning.
