TL-Pro

Bipolar high-voltage supplies

• Continuously adjustable linear output with integrated touchscreen or standalone control. Local or remote computer control supports monitoring and start/stop operation.
• Metal shielding and low EMI support stable operation. Protection covers overvoltage, overcurrent, arcing and short circuits.

Integrated touchscreen control

• Control high voltage, syringe pumps, spinneret motion and the rotating collector from one interface. Adjust parameters during operation, record data and coordinate motion.
• The screen can be stowed at the side of the enclosure.

Dual-channel insulated syringe pump

• Two independent servo-driven channels provide individually adjustable feed rates. High thrust supports viscous liquids, while electrical insulation supports operation under high voltage.
• Internal or external pump configurations are available, with an optional upgrade to 4–8 channels.

Dehumidification

• A compact compressor delivers a gentle flow of dry air. The standard dehumidifier reaches approximately 30% RH at room temperature.
• An enhanced dehumidifier reaching approximately 20% RH is available at extra cost.

Optional mist-free humidifier

• Evaporative humidification maintains uniform chamber humidity while reducing droplet deposition on the collector. Quiet, energy-efficient operation with germicidal protection.

Infrared chamber heating

• Precise temperature control with rapid, uniform infrared heating provides a controlled thermal environment for electrospinning.

Single-needle spinneret

• Includes 100 stainless-steel needles in various sizes. The dedicated holder accepts standard metal needles and allows adjustment of the spinning angle and spinneret-to-collector distance.

Glass microcapillary needles

• Microchannel sizes of 1–45 µm, with inner diameters as small as 1 µm. Suitable for low-viscosity fluids and small-volume experiments, including ultrafine fibers, micro/nanoscale patterning and near-field direct writing.

Low-volume spinneret

• Connect the syringe directly to the needle without tubing. Experiments can use approximately 0.5 mL of solution, reducing consumption of valuable materials.
• Simultaneous operation of two low-volume spinnerets is optional.

Coaxial spinneret

• Five sets of inner and outer needles support core–shell fibers. Inner and outer needles detach and interchange independently; high concentricity supports a stable jet.
• Custom needle lengths are available. Compatible with gas-assisted spinning and supplied via a two-channel syringe pump.

V-shaped dual spinneret

• Apply the same or different voltages to the two needles, including opposite polarities for conjugate spinning. The layout reduces mutual interference, with adjustable angle and distance and graduated scales.

Conjugate electrospinning

• Parallel needles connected to positive and negative high voltage reduce charge accumulation at the collector and support dense layers. Process two materials simultaneously for composite fibers, yarns and specialty structures, with reduced interference for a more stable process.

Side-by-side spinneret

• Two independently controlled channels deliver different materials simultaneously. Five needle sets are available, with compatibility across standard needle sizes.
• Create Janus, self-crimping and other functional composite fibers.

Optional multi-needle arrays

• One inlet feeds multiple outlets to increase throughput. Needle count, spacing and arrangement can be customized in linear, ring or array layouts to improve membrane uniformity.

Automatic needle cleaning

• Clean needles during operation without stopping the process, particularly when using volatile solvents. Set the cleaning frequency according to solvent evaporation. Available for the spinneret types described above.

Spinneret motion and positioning

• Motorized X motion traverses the spinneret along the drum axis, controlled through the touchscreen with data recording. Manual Y and Z adjustments have graduated scales.

Rotating drum collector

• Collect flat membranes with random or aligned fibers. Higher rotation speeds support aligned deposition; the microscopy images show fiber morphologies.

Rotating disc collector

• Collect narrow ribbons of highly aligned nanofibers on the disc edge. Sharp-edge and flat-edge configurations are available.

Rotating mandrel collector

• Produce hollow tubular membranes in different diameters for vascular graft and tubular scaffold research.

Highly aligned fiber collector

• High-speed rotation aligns fibers into narrow, flat membranes and fiber bundles.

Parallel-electrode cage collector

• Collect aligned nanofibers at low rotation speeds and transfer them to other substrates. Electrode spacing can be customized.

Adjustable flat plate collector

• An adjustable-angle stainless-steel plate supports rigid substrates that cannot be rolled. An X–Y motion stage can be added as an option.

Optional configuration

Heated spinneret

• For heated electrospinning and direct writing of low-melting materials, or heating small solution volumes to reduce viscosity. A standard interface simplifies installation and replacement.

Optional configuration

Roll-to-roll collection

• Collect nanofiber membranes continuously. Adjust take-up speed to the required membrane thickness, or select the fixed-length version.

Optional configuration

Spiral yarn collection

• Converge fibers by spiral drawing to form continuous yarns, with or without a core. Change the core material to suit the application. The same approach can build three-dimensional mats, with collection time controlling thickness.

Optional configuration

Thick three-dimensional mats

• Continuously build a porous three-dimensional fiber network. Collection time and process settings determine thickness. Applications include filtration, adsorption, electrodes and tissue-scaffold research.

Optional configuration

Nanoparticle and microsphere module

• A magnetic stirrer on an insulating base works with a microsphere nozzle, dedicated holder and auxiliary electrode. Liquid-bath collection reduces agglomeration for dispersed nanospheres, short fibers and other structures.
• Includes two rotating water-bath vessels.

Optional configuration

Microwire coating collector

• Apply nanofiber membranes to fine wire surfaces. Dual motors maintain stable rotation, with an independent controller and stepless speed adjustment.

Optional configuration

Gas-assisted spinning

• Combine airflow and electric forces to assist fiber formation. Output can substantially exceed conventional electrospinning, depending on the material and process.
• Suitable for polymer solutions, lofted mats, cotton-like three-dimensional structures and short fibers.

Optional configuration

Cross-aligned fiber module

• Form unidirectional or cross-aligned multilayer membranes with alternating 0° / 90° fiber directions. A dedicated spinneret and synchronized rotating dual discs support repeatable orthogonal deposition.
• An independent digital controller supports applications in tissue engineering and composite reinforcement.

Optional configuration

In-situ UV curing

• Automatic curing with uniform irradiation, without removing the sample for a separate post-treatment step. This reduces sample transfers and handling.

Optional configuration

Centrifugal electrospinning

• Centrifugal and electrostatic forces draw the polymer solution into jets that form nanometer- or submicrometer-scale fibers, improving fiber formation efficiency and stability.

Optional configuration

Rotating flat plate collector

• Servo-controlled rotation collects random or aligned membranes, including highly aligned fibers. The plate angle can be customized for the application.

Optional configuration

X–Y motion stage

• Control two-dimensional paths on a flat plate collector with CAD import or programmed input. Includes a handheld controller and control box, timing-belt transmission and stepper motors, with insulating plastic construction.

Optional configuration

Ionizing air blower

• Positive and negative ions regulate charge distribution, while airflow helps distribute fibers. Reduced static buildup limits adhesion and flyaway fibers.
• Supports membrane uniformity, improved morphology with fewer beads, solvent evaporation and environmental control.

Operator and equipment safeguards

• An accessible emergency stop enables rapid shutdown. Automatic power protection cuts off overvoltage and overcurrent.
• The door interlock shuts off high voltage when the door opens. Multi-point grounding connects the enclosure, high-voltage supplies, pumps and collectors.
