Compact Electrospinning Unit – Random & Aligned Nanofibers, 40–60 kV, X-Y Spinneret

Compact Electrospinning Unit is a high-tech system that combines the rotary movement of the collector with the x-y movement of the spinneret to create a uniform substrate of both random or aligned nanofibers, by simply changing the configuration.

Obtain fibers with uniform thickness

With this unit, safe and ready to use, you can electrospin any type of organic, synthetic, or ceramic polymer.
Nanofibers are characterized by a high reproducibility over time and by a uniform thickness along the axis of the collector.

Thanks to the detachable mandrels, collectors of different sizes can be mounted. Besides giving you the possibility to work with collectors of different sizes, that gives you the possibility to obtain tubular structures, avoiding the membrane cutting to peel off the fibers.
It is also possible to install a flat collector easily, by using the provided screws.

The internal chamber can reach a temperature of +50°C.

Compared to a classic rotary collector, this system rotates and the needle moves simultaneously to guarantee a uniform deposition of fibers along the collector.

Why the moving spinneret makes the difference

On a standard rotating collector the needle stays still: the fibers pile up in a narrow band and the deposit is thicker in the middle than at the edges. Here the spinneret travels along the collector while it rotates, so the material is distributed evenly over the whole length.

In practice this means:

• Uniform membranes - consistent thickness along the collector axis, not just at the centre.
• Usable area - the full Ø80×300 mm collector is covered, so you get more sample per run.
• Tubular scaffolds - vascular grafts, nerve conduits and stents can be produced with even wall thickness and peeled off whole, without cutting.
• Reproducibility - fewer manual variables between one batch and the next.

What you can make with it

• Biomedical & tissue engineering - aligned scaffolds that guide cell orientation, tubular structures, wound dressings.
• Pharmaceutical - drug-loaded membranes for controlled release.
• Filtration - high surface-area nanofiber media on flat or cylindrical supports.
• Energy & sensors - functional mats where fiber orientation drives performance.

The chamber reaching +50 °C also helps with polymers that need a warmer environment to spin cleanly or to evaporate solvent faster.

Unit includes:

• Electrospinning chamber;
• Rotating system;
• X-Y movement for the needle;
• High voltage generator 40kv (available with 60kV too);
• Syringe Pump with local and/or (available with local and remote control - single or double channel);
• Rotary collector up to Ø80*300mm (L);
• Plexiglass Support 200*300mm;

• 1mt teflon tube with male and female fittings;

Options and upgrades

The unit can be configured and extended over time:

• 60 kV generator instead of the standard 40 kV, for polymers that need a stronger field.
• Double channel pump or remote control - see the remote control syringe pump.
• Coaxial needles for core-shell fibers and encapsulation.
• Multiple needle emitters (4, 6 or 14 tips) to increase throughput.
• Heating needle system up to 250 °C for melt electrospinning, without solvents.
• Collectors of different diameters and geometries.

Which complete system fits your project?

The Compact Electrospinning Unit is the smallest complete system that already gives you both random and aligned fibers with a moving spinneret. Every Linari machine is delivered ready to run - chamber, generator, pump, needles and collectors included - so the choice is only about scale and level of control.

Compact Unit Uniform membranes, small footprint	Moving spinneret plus rotary collector up to Ø80×300 mm, chamber up to +50 °C, 40 or 60 kV. For uniform membranes and tubular scaffolds where space matters.
Starter Kit - random / aligned Most accessible entry point	Complete benchtop stations with 40-60 kV generator, pump, needles and syringes - static collector for non-woven mats, or the rotary system for aligned fibers and tubular structures.
All In One Modular R&D platform	40 kV multi-collector system with syringe pump drawer; roll-to-roll up to 300 mm, XY gantry and external air treatment unit can be added later, on a machine already installed.
Gantry 3D Spin Programmed precision	G-code control of the emitter path from CAD, or CSV from a spreadsheet, with adjustable needle-collector distance during the run.
RT Advanced / Pilot Spinner Industrial	Up to 8 materials at once with controlled atmosphere and unattended production, or a drum collector up to Ø250×600 mm when what you need is quantity per batch.

Frequently asked questions

Can it produce both random and aligned nanofibers?

Yes. By changing the configuration and the collector rotation speed you obtain either a randomly oriented non-woven mat or aligned fibers, on the same unit.

What makes it different from a normal rotating collector?

The spinneret moves along X-Y while the collector rotates, so fibers are deposited evenly along the whole collector axis instead of piling up in a narrow band. The result is a membrane of uniform thickness.

Can I make tubular scaffolds?

Yes. Thanks to the detachable mandrels you can mount collectors of different sizes and produce tubular structures, then remove the collector without cutting the membrane to peel off the fibers.

What size collector does it take?

The rotary collector goes up to Ø80×300 mm in length, and a flat collector can be installed easily with the provided screws.

Which materials can I electrospin?

Any organic, synthetic or ceramic polymer, starting from solutions. The internal chamber can reach +50 °C, which helps with polymers that need a warmer environment or faster solvent evaporation. With the heating needle system you can also work in melt electrospinning, without solvents.

Can I upgrade it later?

Yes. Generator up to 60 kV, double channel or remote controlled pumps, coaxial and multi-needle emitters, heating needles and additional collectors can be added after installation.

Is there a system with a larger collector?

Yes. The All In One takes multiple collector types and an optional roll-to-roll up to 300 mm, while the Pilot Spinner reaches a drum collector of Ø250×600 mm for pilot production quantities.

How do I know if my material can be electrospun?

You can ask espin.ai for a starting set of process parameters, or have our laboratory in Pisa run a feasibility test on your material and characterize the fibers by SEM before you decide.
