The Fluidnatek LE-500 BioFlat is an LE-500 electrospinning platform specifically configured for medical flat sheets production, with high process control. It combines roll-to-roll collector with conveyor belt mechanism, large-volume solution feeding systems up to 8L, multiple multi-emitter spinning heads (37 emitters each), environmental control, and automation tools to support reproducible manufacturing and pilot-scale development, all the process data-driven.

Engineered electrospinning machine for the production of electrospun medical flat sheets, such as wound dressings, patches, flat scaffolds, etc.
The Fluidnatek LE-500 BioFlat electrospinning machine is designed for production of medical flat sheets, combining the process control needed for validated manufacturing (e.g. under GMP or ISO 13485) with the flexibility required for R&D and pilot-scale work.
This system incorporates Fluidnatek’s experience gained through multiple biomedical electrospinning projects relating wound healing patches, where reproducibility, process control, and product homogeneity, and consistency batch-to-batch, as well as system-to-system matching, are critical requirements. That experience is reflected in the platform design, which focuses on clean chamber operation and hygienic design, reproducible batch-to-batch performance thanks to a tight process control on many variables affecting the electrospinning process, and compatibility with controlled manufacturing workflows.
Maximum process control is reinforced by the Fluidnatek Environmental Control Unit (ECU), which provides precise temperature and humidity control inside the chamber and works together with the actively regulated exhaust system to maintain stable and safe operating conditions.
If required by the customer, Fluidnatek can support process development and validation activities such as DQ/IQ/OQ (Design Qualification | Installation Qualification | Operational Qualification), including also PQ (Performance Qualification) if needed, so the machine can be delivered with a specific process that has been optimized in line with the established product requirements and specifications for the electrospun material.
For medical flat sheets production, validation, documentation, and repeatability are essential. The Fluidnatek LE-500 BioFlat electrospinning systems is designed to support those requirements with a platform built for tightly controlled processing and scalable manufacturing.

Thanks to its high level of process control, environmental regulation, and medical-manufacturing-oriented features, the platform is particularly suitable for applications where reproducibility, uniformity, and product consistency are critical requirements.
Typical applications include:
The Fluidnatek LE-500 BioFlat provides the process control and scalability required to transition these applications from early-stage development to reproducible pilot-scale production.
Since initiating our experience with ISO 13485 and GMP (Pharma)-certified processes and cleanroom manufacturing facilities in 2017, Fluidnatek has applied the same engineering principles to the Fluidnatek LE-500 BioFlat electrospinning platform. The result is a spinning chamber with a hygienic design, that maintains ISO 7 cleanliness grade (or up to ISO 5), equipment compatible with cleanroom installation, and is constructed from robust, solvent-cleanable materials throughout.
The platform uses cleanable materials, helping support operation in controlled environments where cleanliness and repeatability matter. Also system-to-system matching is key when managing fleets with multiple pieces of equipment manufacturing the same electrospun material. This design logic is aligned with the demands of medical flat sheets production.
HEPA filtration is implemented in the Fluidnatek LE-500 BioFlat machine to maintain the required air cleanliness within the spinning chamber (inlet air and/or exhaust). Robust, solvent-cleanable materials are used throughout the chamber construction, supporting thorough cleaning between production batches and the hygienic conditions required for ISO and GMP-compliant medical device manufacturing.
Control and precision in solution delivery are critical in medical and pharmaceutical device manufacturing. The Fluidnatek LE-500 BioFlat solution feeding systems are engineered to meet demanding requirements for solution dispensing at every production scale, whether at small-scale with high-pressure syringe pumps of great performance, or at large-scale with gravimetrically controlled large-volume systems (up to 4L each).
The Fluidnatek LE-500 BioFlat uses a gravimetrically controlled peristaltic liquid feeding system with a 4-liter solution reservoir. High-pressure syringe pumps are also available. With dual peristaltic solution feeding systems, the equipment supports batches of up to 8 liters of spinning solution, enabling extended semi-continuous flat sheet production runs.
A second solution feeding system can be integrated, enabling simultaneous deposition of two different materials within the same electrospun flat sheet — for example, combining bioactivity and mechanical strength in a single membrane or wound dressing structure.
Product consistency is one of the most important requirements in medical and pharmaceutical device manufacturing. The Fluidnatek LE-500 BioFlat equipment includes process automation features designed to reduce operator error and improve batch repeatability, including programmable multi-step recipes in-line thickness metrology.
The platform may integrate in-line metrology systems capable of measuring deposition thickness and/or area density (gsm) during production. These systems can be configured to automatically stop the process once the target deposition value is reached, helping reduce end-point variability and improve batch-to-batch consistency.
The Fluidnatek LE-500 BioFlat supports in-line thickness measurement in rotating collectors, as well as in-line area density measurement. By providing real-time process feedback, these tools support tighter process control, reduced material waste, and more reproducible manufacturing outcomes.
Stable temperature and humidity within the spinning chamber are also prerequisites for a reproducible electrospinning process and consistent medical flat sheet quality. As one of the first companies to develop climate control systems designed specifically for electrospinning process in our electrospinning equipment, Fluidnatek has built extensive expertise in this area.
The Fluidnatek Environmental Control Unit (ECU) is capable of heating, cooling, drying, and humidifying the spinning environment.
