Fluigent MFCS-EZ Precision Pressure-Driven Microfluidic Flow Control System

Overview

The Fluigent MFCS-EZ is a high-precision, pressure-driven microfluidic flow control system engineered for demanding laboratory applications requiring sub-nanoliter resolution, dynamic pressure modulation, and exceptional temporal fidelity. Unlike conventional peristaltic or syringe-based pumps—whose mechanical actuation introduces pulsatility, backflow, and limited low-flow capability—the MFCS-EZ employs closed-loop pneumatic pressure regulation to deliver continuous, pulseless, and programmable fluid propulsion across complex microchannel architectures. Its core principle relies on digitally controlled pressure differentials applied to reservoirs connected via gas-tight tubing to microfluidic chips, enabling precise volumetric displacement without direct contact between the actuation mechanism and the sample fluid. This architecture eliminates shear-induced degradation of sensitive biological entities (e.g., cells, vesicles, proteins), supports ultra-low flow regimes down to 1 nL/min, and ensures stability compliant with GLP and ISO/IEC 17025 traceability requirements for quantitative microfluidic experimentation.

Key Features

• Independent real-time pressure control across 1–4 channels, each configurable with user-selectable pressure ranges (−800 mbar to +7 bar) and resolution of 0.03% FS
• Sub-100 ms settling time and <40 ms system response latency, enabling rapid protocol transitions and closed-loop flow regulation
• Integrated software platform (Fusion™) supporting script-based automation, multi-step pressure profiles, and synchronized hardware triggering via TTL/USB
• Optional integrated flow sensors (e.g., QX series) provide real-time volumetric feedback, enabling active pressure compensation to maintain constant flow under variable channel resistance
• Gas-compatible design certified for use with inert, non-corrosive, non-explosive gases (N₂, CO₂, dry air); no internal wetted metal parts ensure chemical compatibility with aqueous, organic, and low-surface-tension fluids
• Compact benchtop form factor (240 × 170 × 75 mm), 24 V DC power input, and 15 W nominal consumption support integration into enclosed instruments or cleanroom environments

Sample Compatibility & Compliance

The MFCS-EZ is compatible with standard microfluidic chip interfaces (e.g., PDMS, glass, PMMA, COP) and supports both positive and negative pressure operation—critical for bubble-free priming, reverse-flow washing, and vacuum-assisted cell trapping. It meets essential safety and performance benchmarks for research-grade instrumentation: CE marking per EU Directive 2014/30/EU (EMC) and 2014/35/EU (LVD); RoHS 2011/65/EU compliance; and design alignment with ISO 8573-1 (compressed air purity) for gas supply integrity. While not a medical device, its pressure accuracy (<0.1% FS stability), audit-trail-capable software logging, and deterministic timing behavior render it suitable for method development under FDA 21 CFR Part 11–aligned workflows when deployed with validated procedures and electronic signatures.

Software & Data Management

Fusion™ software provides native Windows/macOS/Linux support with intuitive graphical interface and Python/C++/MATLAB APIs. All pressure setpoints, timestamps, sensor readings, and error states are logged in HDF5 format—including metadata tags for experimental context (user ID, protocol version, chip ID). The software enforces role-based access control, supports digital signature capture for critical parameter changes, and generates timestamped, tamper-evident reports compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Optional cloud synchronization enables centralized instrument fleet monitoring and remote troubleshooting without compromising local data sovereignty.

Applications

• Single-cell manipulation and hydrodynamic focusing in microfluidic cytometry platforms
• Continuous perfusion of 3D organoids and microphysiological systems (MPS)
• Controlled droplet generation and coalescence in double-emulsion and segmented-flow reactors
• Dynamic gradient generation for chemotaxis assays and dose-response screening
• Calibration and validation of on-chip viscometers, particle image velocimetry (PIV) setups, and optical trapping systems
• Microscale reagent delivery in automated ELISA, immunoassay, and nucleic acid amplification cartridges
• Stable fiber-optic sensor interrogation using pressure-regulated reference fluid paths

FAQ

Can the MFCS-EZ be used with organic solvents such as DMSO or ethanol?
Yes—provided all fluidic path components (tubing, connectors, chip interfaces) are chemically compatible. The MFCS-EZ itself contains no wetted elastomers or metals; only the external gas lines contact the actuation medium.
Is flow rate calibration required when switching between pressure ranges?
No—pressure transducers are factory-calibrated across all selectable ranges. Flow rate accuracy depends on chip-specific hydraulic resistance and optional flow sensor calibration, not pressure channel selection.
Does the system support synchronization with external equipment (e.g., cameras, lasers)?
Yes—via TTL input/output ports and software-triggered events with sub-millisecond jitter, enabling hardware-level coordination with high-speed imaging or pulsed light sources.
What maintenance is required for long-term operational reliability?
Annual verification of pressure transducer linearity and zero drift is recommended. No routine consumables or recalibration kits are required under normal operating conditions.
Can multiple MFCS-EZ units be operated from a single Fusion™ instance?
Yes—up to eight units can be daisy-chained via USB hubs or managed concurrently over Ethernet (with optional network module), with synchronized timeline execution and unified data export.
