The enhanced performance of textiles by imparting properties such as water resistance, flame retardancy, and antimicrobial activity can be accomplished using electrospun materials. These fibers are used in lightweight protective clothing, wound dressings, and specialty textiles for various applications.

Filtration & Separation

 Nanofibrous membranes produced by electrospinning are employed in filtration and separation processes due to their small pore size and high porosity. They are used in air filtration, water filtration, oil-water separation, and other environmental applications. This can be done using high-throughput electrospinning methods, such as needle-less electrospinning.

Batteries & Fuel Cells

 Energy storage and conversion devices such as batteries, supercapacitors, and fuel cells utilize electrospun nanofibrous materials for improved performance of these devices due to their high surface area and electrical conductivity. Ease of particle incorporation, such as ceramic/inorganic nanoparticles, and homogeneity in electrospinning promotes the efficiency of the fibrous materials electroconductivity.

Product Accessories

Environmental Control Unit or Dry Heating Unit

ECU provides tightly controlled temperature (18-45°C) and relative humidity (10-80%) with HEPA filtration, a necessity for ensuring reproducible and consistent electrospinning results. DHU provides an alternative environmental control for solution processing requiring low humidity (ambient RH down to 25% at 25ºC, or down to 10% at 45ºC) and/or increased temperature (RT up to 45ºC).

High Definition Process Data Hub
HDPDH provides real-time updates, monitoring, and control of the electrospinning unit with 20+ viewable process parameters. This powerful, unique Industry 4.0 software tool provides a detailed record of process stability over time. The Process Data Hub ensures process consistency and repeatability between batches and across platforms, providing smooth scalability to higher throughput.
High Voltage Options

With multiple independent high voltages available in the unit, bias can be applied to additional emitters and/or collector. Additionally, voltages can be upgraded to bipolar capacities of -30kV to +30kV (emitter) or –10kV to 10kV (collector). Multiple adjustable voltages and a secondary stage in tandem provide configuration flexibility, such as co-spinning or dual spinning/spraying, emitter/collector voltage inversion for specific orientation, or preferential sample deposition/morphology.

Multiple Syringe Pumps
The LE-50 can accommodate up to 3 single syringe pumps within the electrospinning chamber. Implementing 2 or more syringe pumps opens the door to multi-solution processing for coaxial, triaxial, or co-spinning (AKA dual spinning) sample formation. Simultaneous use of multiple solutions enables the creation of composite or layered fibers with diverse properties for advanced applications. This setup also increases productivity by enabling higher throughput and flexibility in controlling fiber characteristics, such as morphology and composition, for producing more complex and multifunctional materials.
Needle Translation

The LE-50 equipped with improves sample homogeneity and thickness with needle translation. This helps produce more uniform fibers by distributing the electrospun solution more evenly across the collector, reducing fiber defects and ensuring consistent fiber diameter. Additionally, it enhances productivity by increasing the deposition area, allowing for the fabrication of larger, more uniform samples efficiently.

Adjustable Emitter Orientation

LE-50 compatible emitters can be positioned vertically and horizontally on independent spinning stages or angled (using an articulating flexible arm). Vertical orientation for top-down spinning or spraying onto collectors or water bath providing options for improved solution processing or particle collection. Horizontal and angled positioning prevent solution dripping onto collectors, easily allowing solution optimization or low viscosity solutions to be processed without defect to the final sample.

Taylor Cone Visualization System

The Taylor cone visualization system uses a high-quality camera to focus directly on the emitter needle tip for a close view of Taylor cone formation and solution processing. Taylor cone formation is indicative of the electrospinning quality and is therefore crucial for monitoring during process optimization. By observing the cone shape and stability in real-time, operators can quickly adjust parameters such as voltage or flow rate to ensure consistent fiber production and reduce defects. This leads to improved control over fiber diameter, morphology, and quality, resulting in a more efficient and reliable electrospinning process.

Emitter Variety

The LE-50 accommodates both needle-based (single phase, coaxial, triaxial, multi-needle, gas-assisted) and needle-less (slit injector) emitter forms all in a single electrospinning unit. This extensive array of emitters means and equally extensive array of fibers and particles morphologies are possible, including core-shell, core-shell-shell, hollow, textured, porous, and many more. Gas-assisted and solvent-gas jacket configurations provide assistance in spinning difficult or low boiling point solutions. Additionally, multi-needle and slit injector (needle-less) options can increase overall throughput and sample productivity.

Collector Variety

In addition to a standard flat plate configuration for randomly oriented fibers, the LE-50 can be equipped with a rotating drum, rotating mandrel, or rotating disk collector for various types of sample deposition. These collectors provide a controlled, dynamic surface for fiber deposition, leading to the production of aligned or oriented fibers, which can enhance mechanical properties such as tensile strength. Rotating collectors can improve uniformity and consistency in fiber distribution, and when paired with needle translation the continuous motion helps to avoid buildup in any one area, facilitating the production of non-woven mats with consistent thickness and density over larger areas for increased productivity.

Syringe Heating

Syringe heating can be implemented from 30°C to 120°C for processing of viscous or temperature-specific solutions. Controlled heating of solutions can enhance the flow and reduce viscosity, resulting in smoother and more consistent fiber production. This can be especially useful for polymers with high melting points or that are difficult to dissolve at room temperature. Syringe heating also improves process stability, quality, and efficiency, as it reduces clogging and maintains a steady flow rate throughout the electrospinning process.

Instrument Certifiability

The high-quality, professional nature of the Fluidnatek line provides the basis for GMP, GLP, GAMP, FDA, and/or ISO-13485 certifiable electrospinning machines. This certification enhances product reliability, consistency, and safety, making electrospun materials suitable for medical, pharmaceutical, and other regulated industries. It also builds trust with clients and stakeholders, demonstrating commitment to compliance and quality control, setting the machine apart from competitors and opening doors to broader market access and potential collaborations.
