The Fluidnatek LE-50 ProSterile is a benchtop platform designed for aseptic electrospinning for producing sterile electrospun products and in-line aseptic bioprocesses. It is built for medical, biomedical, and research environments where cleanliness, control, and reproducibility are essential. Applications such as tissue engineering in personalized medicine and medical bed-side applications are ideal for the Fluidnatek ProSterile electrospinning machine.

Its ISO 5 chamber cleanliness, welded stainless-steel construction, glove port access, vacuum antechamber pass-through, and up to 3 combined sterilization techniques are designed to support sterile manufacturing workflows and minimize contamination risk throughout the process. The platform is intended for applications where maintaining chamber integrity is critical from setup to production.

The Fluidnatek LE-50 ProSterile also integrates multi-emitter spinning heads (5 emitters or up to 10 emitters per spinning injector, with the possibility to also include field deflectors), high-pressure 2-channel syringe pump, Fluidnatek Environmental Control Unit (ECU), and an actively regulated exhaust system to help maintain stable process conditions during electrospinning. These features make it suitable for controlled development work as well as more demanding aseptic production scenarios.

Where required, Fluidnatek can support regulated projects with IQ/OQ (Installation Qualification | Operational Qualification) documentation, on-site services, and even Performance Qualification (PQ), helping customers move from development into validated aseptic production. This makes the platform a strong fit for teams that need both process control and a clear path toward compliance with electrospun medical devices sterile-made.

Chamber Sterilization Systems

The Fluidnatek LE-50 ProSterile can integrate up to 3 combined sterilization techniques to support aseptic processing before, during and after production. These sterilization systems are designed to reduce contamination risk and support validated aseptic manufacturing workflows while helping maintain controlled chamber conditions throughout production.

Glove Port Access and Vacuum Antechamber Pass-through

To maintain chamber integrity during operation, the Fluidnatek LE-50 ProSterile includes glove port access and a vacuum antechamber pass-through. Glove ports allow operator intervention without opening the chamber and avoiding contamination, while the vacuum antechamber supports the transfer of materials and accessories without breaking the sealed environment. Together, these features help preserve aseptic conditions during setup, loading, and unloading.

Why Aseptic Electrospinning Matters

Medical devices, tissue engineering scaffolds, solutions of personalized medicine with patients, and other biomedical products manufactured by electrospinning often require highly controlled production environments. Even minor variations in environmental conditions or unwanted contamination can affect product quality, process reproducibility, and the ability to validate manufacturing workflows.

Aseptic electrospinning is designed to minimise these risks by combining contamination control, environmental stability, and process standardisation throughout production. Unlike conventional laboratory electrospinning systems, the aseptic Fluidnatek ProSterile electrospinning platform incorporate features that help maintain controlled the spinning chamber conditions while allowing operators to safely interact with the process and transfer materials without unnecessarily exposing the manufacturing environment.

The Fluidnatek LE-50 ProSterile integrates several complementary technologies that support these objectives, including hygienic design,  ISO 5 chamber cleanliness level, glove port access, vacuum antechamber pass-through, combination of multiple sterilisation systems, actively regulated exhaust system, environmental control, automated process management, and Process Data Hub for data-driven decisions.

Together, these capabilities help create stable operating conditions that achieve a great robustness and reliability, process repeatability and batch consistency, and facilitate documentation for regulated development projects.

Environmental Control for Reproducible Electrospinning

Maintaining stable environmental conditions is essential for achieving consistent electrospinning performance. The Fluidnatek LE-50 ProSterile incorporates a dedicated Fluidnatek Environmental Control Unit (ECU) designed specifically for electrospinning applications, providing precise control of both temperature and relative humidity throughout the manufacturing process.

The ECU supports independent heating, cooling, drying, and humidifying functions, therefore all degrees of freedom, allowing operators to establish stable process conditions according to the requirements of each material and application.

Unlike general-purpose climate control systems, the Fluidnatek ECU has been specifically developed to manage the evaporative nature of electrospinning processes, where environmental fluctuations can significantly influence process stability and product consistency.

To further improve process reliability, the Fluidnatek Environmental Control Unit (ECU) operates in synchrony with the actively regulated exhaust system, optimizing gas extraction at all time as well as generating a slight negative pressure in the spinning chamber, to enhance operator safety.

Together, these systems maintain controlled chamber conditions while optimising solvent extraction, supporting safe operation and helping minimise process variability during electrospinning.

For facilities operating in cleanroom or regulated manufacturing environments, the Environmental Control Unit can be installed in a dedicated service corridor outside the cleanroom.

The hygienic design of the Fluidnatek ProSterile electrospinning platform, and the HEPA filtration, further contribute to maintaining ultra-clean processing conditions inside the spinning chamber, supporting applications that require tightly controlled manufacturing environments.

Precise Solution Dosage

The Fluidnatek LE-50 ProSterile is equipped with a high-pressure 2-channel syringe pump designed to deliver precise and stable solution feeding throughout the electrospinning process, even when using viscous solutions.

Accurate dosing is particularly important in biomedical and pharmaceutical applications, where stable flow rates directly influence process reproducibility, product quality, and batch-to-batch consistency.

The system is well suited to research, process development, and regulated manufacturing environments that require controlled solution delivery and repeatable electrospinning conditions.

A second high-pressure syringe pump can be installed, enabling the possibility of increasing the solution volume, or producing coaxial spinning (core-shell structures) if using a coaxial spinning head, or the simultaneous deposition of two different materials if using a secondary spinning stage (so called “dual spinning”). This allows the development of composite electrospun structures with complementary properties, supporting advanced applications in tissue engineering, drug delivery, and biomedical materials research.

Automation for Batch-to-Batch Consistency

The Fluidnatek LE-50 ProSterile includes programmable sequential multi-step recipe function, multi-user access, batch control, and high-definition process data collection. These functions reduce operator variability and provide process insights and track record, thus supporting more consistent batch-to-batch production. For regulated applications, they also improve traceability and make the process easier to document and validate.

Applications involving Sterile Electrospinning

The Fluidnatek LE-50 ProSterile is designed for advanced electrospinning applications where aseptic processing, contamination control, and process reproducibility are essential.

Typical application areas include:

• Personalised medicine – Fabrication of patient-specific electrospun materials for wound healing or tissue regeneration requiring aseptic processing throughout product development.
• Tissue engineering – Production of nanofibrous scaffolds for cell culture, supporting controlled cell growth and tissue regeneration studies.
