VIVOLTA’s electrospinning equipment turns one platform into many. From flat membranes to tubular scaffolds, the EC-CLI’s modular collectors, nozzles, and process-control modules install in minutes and run through the same touch-screen UI — so you can tailor a single system to virtually any application.
Maximum scaffold porosity with EM-LTE collector
EM-TMM thickness measurement variation (5σ)
Every add-on connects through a standardized mechanical and electrical interface, and is controlled through the EC-CLI’s integrated touch-screen UI — so expanding capability never means added complexity. Whether you need to produce highly porous scaffolds with a low-temperature collector, electrospin core–shell nanofibers through a coaxial nozzle, or monitor layer thickness in real time with laser metrology, each module is engineered for plug-and-play installation and immediate, reproducible results.
Below you’ll find every piece of electrospinning equipment available for the EC-CLI platform — collectors, nozzle systems, process-control modules, and accessories — all developed by the team behind VIVOLTA’s MediSpin™ clinical manufacturing system.
From millimeter-scale mandrels to large rotating drums and cryogenic collectors, the EC-CLI’s collector range covers every geometry and porosity requirement.

Stabilize the Taylor cone & prevent nozzle clogging with volatile solvents

Eliminate static charge build-up for reproducible electrospinning
High voltages can build up electric charge on equipment and inside electrospun materials, disturbing the process. Mounted in the EC-CLI chamber ceiling, the EM-ASM uses fully controlled active ionization to neutralize accumulated charge before, during, and after spinning.

Yes. VIVOLTA offers comprehensive on-site installation, user training programs, and ongoing technical support worldwide — including the US (Dallas, TX), Japan, and Australia. Our team provides guidance on system configuration, module selection, and process development. Custom process-development support is available from VIVOLTA’s in-house scientists, and extended service and maintenance packages keep your electrospinning equipment running at peak performance.
Several equipment strategies help. The EM-MN4 multi-nozzle uses four parallel nozzles to multiply fiber deposition. Adding an EM-TNS translation nozzle stage to the EM-RDC or EM-RTC collector enables a second nozzle to operate simultaneously, doubling throughput. Linking multiple EP-HRU syringe pumps gives synchronous flow control for multi-channel setups. All of these can be combined in a single session for maximum throughput.
Coaxial electrospinning produces core–shell nanofibers where the core and shell are different materials — enabling drug encapsulation, fiber reinforcement, and surface functionalization. You’ll need the EM-CAX coaxial nozzle (0.4 mm core, 1.2 mm shell — custom sizes on request) and typically two independent EP-HRU syringe pumps for independent flow control. The EM-CAX is also compatible with the EM-GSM gas shield for volatile solvent systems.
The EM-TMM uses a laser-based differential distance measurement principle. A laser module mounted on a precision metrology frame measures the distance to the collector surface and to the growing electrospun layer — calculating thickness from the difference. It works reliably even on highly porous structures. Variation is typically 5σ < 50 µm, and the system monitors layer build-up at one or more locations simultaneously, even at high collector speeds.
For flat membranes up to 200 × 300 mm with controllable alignment, the EM-RDC rotating drum collector is the standard choice. For tubular structures — from millimeter-scale vascular grafts to larger tissue-engineering tubes — the EM-RTC rotating target collector accepts custom mandrels and drums from Ø0.5 to 90 mm. If you need highly porous scaffolds with void-templating via ice crystals, the EM-LTE low-temperature collector achieves up to 99.8% porosity. For quick material screening, stationary EM-CXX collector plates on the EM-STD nozzle stand provide a simple, fast setup.
Yes. Every EC-CLI add-on module is designed with a plug-and-play architecture and can be added to any existing EC-CLI system at any time — no hardware modifications to the base machine are needed. Modules are controlled through the integrated touch-screen UI and, in most cases, require no additional software installation beyond optional upgrades.
