{"product_id":"pure-spinner","title":"Pure Spinner – Bulk Production of Substrate-Free Nanofibers","description":"\u003ch3\u003ePure Spinner produces nanofibers as a material, not as a coating. A horizontal-axis collector of up to 0.47 m², up to 140 needles, eight pumps and a digitally controlled blow spinning module — with no substrate to contaminate what you make.\u003c\/h3\u003e\n\n\u003cp\u003eMost pilot systems are built around a roll-to-roll web: the fibre is born attached to something. That is the right answer for coated media, and the wrong one if the fibre \u003cem\u003eis\u003c\/em\u003e the product.\u003c\/p\u003e\n\n\u003cp\u003eIf you are making nanofiber-based additives, inks, chopped fibres or fillers, a substrate is not a support — it is a source of release and contamination. Pure Spinner has no substrate by design.\u003c\/p\u003e\n\n\u003ch2\u003e0.47 m² of collection area\u003c\/h2\u003e\n\n\u003cp\u003eThe largest drum is \u003cstrong\u003eØ250 × 600 mm\u003c\/strong\u003e: a collecting surface of \u003cstrong\u003e0.47 m²\u003c\/strong\u003e. For comparison, the largest mandrel offered on competing laboratory and medical platforms is around Ø30 × 400 mm — roughly \u003cstrong\u003eone twelfth\u003c\/strong\u003e of the area.\u003c\/p\u003e\n\n\u003cp\u003eWe publish the area rather than a production rate on purpose. Throughput in electrospinning depends on the polymer, the solvent, the concentration and the ambient conditions, so any number we printed would be true for one recipe and misleading for yours. Collection area is geometry: it holds whatever you spin.\u003c\/p\u003e\n\n\u003ch2\u003eDeposition that is uniform across the whole drum\u003c\/h2\u003e\n\n\u003cp\u003eThe emitters translate along the full \u003cstrong\u003e600 mm\u003c\/strong\u003e of the drum at up to \u003cstrong\u003e1000 mm\/s\u003c\/strong\u003e — a complete pass in six tenths of a second. While the drum turns once, the emitters have crossed it several times in both directions.\u003c\/p\u003e\n\n\u003cp\u003eThat overlap is what makes 0.47 m² a usable figure rather than a nominal one: the deposit is even along the axis, not concentrated in the middle where the needles happen to sit.\u003c\/p\u003e\n\n\u003ch2\u003eAligned fibres too, when you need them\u003c\/h2\u003e\n\n\u003cp\u003eCollector speed spans \u003cstrong\u003e2000 rpm on small collectors down to 100 rpm on the largest drum\u003c\/strong\u003e, and what matters for fibre orientation is peripheral speed, not rpm.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall collectors at 2000 rpm\u003c\/strong\u003e reach \u003cstrong\u003e8.4 m\/s\u003c\/strong\u003e on a Ø80 mm drum and over 10 m\/s on Ø100 — fully in the regime where fibres are drawn and aligned, for oriented mats and tubular structures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe Ø250 mm drum at 100 rpm\u003c\/strong\u003e runs at about 1.3 m\/s. That is deliberate: for bulk pure fibre you want an even, unstressed deposit over the largest possible area, not alignment — the material is processed and often chopped afterwards anyway.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eOne machine covers both, by changing the collector.\u003c\/p\u003e\n\n\u003ch2\u003eThe collector is the product\u003c\/h2\u003e\n\n\u003cp\u003eBecause the fibre is what you are selling, the collector is not a fixture — it is where quality is won or lost.\u003c\/p\u003e\n\n\u003cp\u003eIt is \u003cstrong\u003eremovable and extracted on a wheeled support\u003c\/strong\u003e, so nobody handles or touches the fibre during unloading. The loaded collector is then processed \u003cstrong\u003eoutside the machine\u003c\/strong\u003e — thermal treatment, chemical or physical steps chosen for the material — and the fibre is recovered there.\u003c\/p\u003e\n\n\u003cp\u003eCollectors are made in different metals and can be \u003cstrong\u003ecoated, for example in titanium nitride (TiN)\u003c\/strong\u003e. TiN is an unusually good answer here because it is two things at once: extremely hard, so the surface does not scratch or wear and releases essentially no particulate into the fibre; and \u003cstrong\u003eelectrically conductive\u003c\/strong\u003e, so it does not degrade the field the way an insulating protective coating would. Purity and process efficiency in the same surface.\u003c\/p\u003e\n\n\u003ch2\u003eElectrospinning, electro-blow spinning, and blow spinning without high voltage\u003c\/h2\u003e\n\n\u003cp\u003eThe optional \u003cstrong\u003edigitally controlled blow spinning module\u003c\/strong\u003e adds a gas flow that helps draw the jet. It raises throughput, and it lets you process solutions that will not open under electric field alone — more viscous, less conductive, or in solvents that resist electrospinning.\u003c\/p\u003e\n\n\u003cp\u003eIt also \u003cstrong\u003eruns without high voltage at all\u003c\/strong\u003e, as pure solution blow spinning. That is not a variant of the same process: it is a second technology on the same machine, and it opens polymers that electrospinning cannot handle.\u003c\/p\u003e\n\n\u003cp\u003eGas flow is set digitally and measured with a \u003cstrong\u003eCoriolis flow meter\u003c\/strong\u003e, which reads \u003cem\u003emass\u003c\/em\u003e flow rather than volume — so it is unaffected by pressure and temperature, and the same setting gives the same result in January and in July. Most hybrid systems use a float meter and a hand valve.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eTwo independent blow spinning systems\u003c\/strong\u003e can be fitted, one per high voltage generator, so two materials can be processed with their own gas flow and their own voltage in the same run.\u003c\/p\u003e\n\n\u003ch2\u003eTwo generators, eight pumps, and the collector as a shield\u003c\/h2\u003e\n\n\u003cp\u003ePure Spinner takes \u003cstrong\u003eup to two 40 kV generators\u003c\/strong\u003e, each feeding a group of \u003cstrong\u003efour pumps\u003c\/strong\u003e. The two groups sit \u003cstrong\u003esymmetrically on either side of the collector\u003c\/strong\u003e, which acts as an electrostatic shield between them.\u003c\/p\u003e\n\n\u003cp\u003eThat layout is what makes eight pumps workable. Multi-emitter systems normally fight themselves: jets repel each other and the field distorts. With the drum in the middle, each group works against a controlled potential rather than against the other group.\u003c\/p\u003e\n\n\u003cp\u003eMulti-needle arrays take the machine to \u003cstrong\u003eup to 140 needles in total\u003c\/strong\u003e. And because the two sides are independent, the left group and the right group can run different materials, different voltages and different gas flows onto the same drum — a blended or hybrid structure in a single run.\u003c\/p\u003e\n\n\u003ch2\u003eNo tubes, and needles that clean themselves\u003c\/h2\u003e\n\n\u003cp\u003ePure Spinner shares the architecture of \u003ca href=\"https:\/\/www.linarinanotech.com\/products\/rt-advanced\"\u003eRT Advanced\u003c\/a\u003e, turned on its side: the collector axis is horizontal instead of vertical, and \u003cstrong\u003ethe syringes move with the needles\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo tubes between syringes and needles.\u003c\/strong\u003e Nothing is left behind between runs, there is no dead volume at material change, and cross-contamination is structurally prevented — which matters more here than anywhere, because the fibre itself is the product.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic needle cleaning\u003c\/strong\u003e with timed jets of compressed gas.

Its hardness means the surface does not scratch or wear, so it releases essentially no particulate into fibre that has to stay pure; its conductivity means it does not degrade the electric field, as an insulating protective coating would.

The blow spinning module works as pure solution blow spinning with the high voltage off, which opens polymers and solvent systems that electrospinning cannot process. It can also be combined with the field as electro-blow spinning to raise throughput.
