Overview
The Fluigent MFCS-EZ is a high-precision, multi-channel pressure-driven microfluidic controller engineered for demanding applications in academic research and industrial R&D laboratories. Unlike syringe-based actuation systems, the MFCS-EZ operates on a closed-loop pneumatic principle: it regulates fluid flow by precisely controlling gas pressure applied to reservoirs connected via flexible tubing to microfluidic chips or devices. This architecture eliminates mechanical pulsation, enabling truly continuous, pulse-free flow with sub-second dynamic response—critical for time-resolved assays, laminar flow manipulation, and real-time feedback-controlled experiments. Designed and manufactured in France, the MFCS-EZ conforms to CE marking requirements and is widely deployed in GLP-compliant environments where traceable, repeatable fluid handling is essential.
Key Features
- Four independent pressure channels (expandable to eight via modular configuration), each with fully isolated pressure regulation and real-time monitoring.
- Ultra-fine pressure resolution down to 0.03% of selected full-scale range—supporting both ultra-low-pressure applications (e.g., cell membrane deformation studies at ≤25 mbar) and high-force microvalve actuation (up to 7000 mbar).
- Pressure stability better than ±0.1% of full scale over extended operation, ensuring long-term reproducibility in multi-hour perfusion or incubation protocols.
- System-level response time <40 ms and settling time <100 ms—enabling rapid transitions between flow states required for droplet generation, sorting, or dynamic gradient formation.
- Gas-compatible design validated for inert, non-corrosive, non-explosive media including nitrogen, carbon dioxide, and dry air—no internal wetted metal parts ensure compatibility with sensitive biological reagents.
- Integrated safety features: automatic pressure ramping, hardware current-limiting, and overpressure cutoff thresholds programmable per channel.
Sample Compatibility & Compliance
The MFCS-EZ interfaces seamlessly with standard microfluidic substrates—including glass, PDMS, thermoplastics (COC, PMMA), and silicon-based lab-on-a-chip devices—via 6 mm OD push-fit connectors. Its pressure-only actuation mechanism avoids sample contact with moving mechanical components, preserving integrity of shear-sensitive biomolecules, primary cells, and extracellular vesicles. The system complies with ISO 13485-aligned manufacturing practices and supports audit-ready documentation for regulated workflows. When paired with optional Flow Unit sensors, it enables closed-loop pressure-to-flow calibration traceable to NIST-traceable volumetric standards. For pharmaceutical process development, the platform supports 21 CFR Part 11-compliant electronic records when used with validated Fluigent software configurations and appropriate IT infrastructure controls.
Software & Data Management
Fluigent provides a tiered software ecosystem supporting users across experience levels and integration needs. The All-in-One (AIO) interface delivers intuitive real-time visualization of pressure setpoints, actual values, and optional flow-rate data—ideal for method development and teaching labs. The Microfluidic Automation Tool (MAT) enables protocol-driven experiment sequencing, including conditional branching, timed events, and external trigger synchronization (TTL, USB, Ethernet). For advanced integration, the Fluigent SDK offers native C/C++, MATLAB, Python, and LabVIEW APIs with full access to low-level device registers, asynchronous command queuing, and timestamp-accurate logging (≥1 kHz sampling). All software modules generate machine-readable log files (CSV/JSON) compatible with LIMS and ELN platforms, and support metadata tagging aligned with ISA-Tab conventions.
Applications
- Single-cell analysis: Stable, pulsation-free perfusion for live-cell imaging, electrophysiology, and micro-ELISA assays.
- Droplet microfluidics: Precise co-flow and T-junction emulsification with monodisperse generation (CV <2%) across variable viscosities.
- Organ-on-chip systems: Physiologically relevant shear stress control (0.01–20 dyn/cm²) for endothelial barrier modeling and vascular perfusion studies.
- Microscale synthesis: Reproducible reagent metering in continuous-flow photochemistry and enzymatic cascade reactions.
- Rheological characterization: Coupled with micro-PIV or particle tracking, enables local viscosity mapping in confined geometries.
- Fiber optic sensor calibration: Controlled hydrostatic pressure application for Bragg grating or interferometric transducer validation.
FAQ
What distinguishes the MFCS-EZ from syringe pumps in microfluidic applications?
Unlike displacement-based syringe pumps, the MFCS-EZ uses regulated gas pressure to drive flow—eliminating mechanical pulsation, backflow, and compliance-related delays. This results in superior temporal fidelity, especially below 1 µL/min and during rapid state changes.
Can the MFCS-EZ be used under sterile or cleanroom conditions?
Yes—the controller itself remains external to the fluid path; only gas lines and reservoirs enter controlled environments. Optional stainless-steel or fluoropolymer gas manifolds are available for ISO Class 5+ integration.
Is remote operation and network integration supported?
All Fluigent software supports Ethernet-based device discovery and control. The SDK includes RESTful API endpoints and WebSocket streaming for cloud-connected lab infrastructures.
How is pressure calibration maintained over time?
Each channel undergoes factory calibration against reference deadweight testers. Users may perform field verification using optional traceable pressure calibrators; calibration coefficients are stored in non-volatile memory and persist across firmware updates.
Does Fluigent provide OEM support for embedding the MFCS-EZ into third-party instruments?
Yes—Fluigent offers custom mechanical housings, tailored firmware builds, electrical interface adaptations (e.g., CAN bus, RS-485), and full regulatory documentation packages (including IEC 61010-1, EMC reports) for medical and industrial OEM deployment.
