Fluigent MFCS-EX Precision Pressure Controller

Overview

The Fluigent MFCS-EX Precision Pressure Controller is an eight-channel, high-fidelity pneumatic pressure regulation system engineered for demanding microfluidic applications requiring simultaneous, independent, and dynamically stable control of fluidic actuation across multiple parallel channels. Based on closed-loop piezoresistive pressure sensing and proportional solenoid valve actuation, the MFCS-EX delivers precise, low-noise pressure output over a broad operational range—from vacuum conditions as low as −800 mbar to positive pressures up to +7 bar—enabling both aspiration and pressure-driven delivery in a single integrated platform. Its architecture eliminates mechanical hysteresis and thermal drift commonly observed in analog regulators, achieving sub-millisecond response dynamics and long-term baseline stability essential for quantitative microfluidics, such as droplet generation, cell manipulation under laminar shear, and time-resolved perfusion assays.

Key Features

• Eight fully isolated pressure control channels on a single compact module—each channel operates independently with no crosstalk or shared hardware dependencies.
• Programmable pressure ranges spanning vacuum (−800 mbar) to high-pressure (7000 mbar), selectable per channel to match specific fluidic resistance and viscosity requirements.
• High-resolution pressure control with ≤0.03% full-scale resolution and <0.1% full-scale stability over 24 hours at constant ambient conditions.
• Ultra-fast dynamic performance: system response time <40 ms; settling time to ±0.5% of target <100 ms—critical for pulsed flow, rapid switching, and feedback-controlled protocols.
• Robust pneumatic interface compatible with standard 6 mm OD tubing; supports inert, non-corrosive, non-explosive gases including nitrogen, carbon dioxide, and dry air.
• Integrated digital communication via USB 2.0 and optional Ethernet (with external hub), enabling synchronization with external triggers, cameras, or DAQ systems.

Sample Compatibility & Compliance

The MFCS-EX is designed for use with aqueous, organic, and low-viscosity biological media in glass, PDMS, thermoplastic, or silicon-based microfluidic devices. It complies with CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). While not intrinsically safe for hazardous environments, its gas compatibility aligns with ISO 8573-1:2010 Class 4 purity standards when used with filtered, oil-free compressed air or regulated cylinder gas. The controller supports audit-ready operation when paired with Fluigent’s Flow Control Software (FCS) configured for GLP/GMP-aligned workflows—including user access levels, electronic signatures, and change logs traceable to ISO/IEC 17025 and FDA 21 CFR Part 11 requirements.

Software & Data Management

Fluigent’s Flow Control Software (FCS) provides intuitive graphical configuration of multi-channel pressure profiles, including ramping, stepping, cycling, and event-triggered sequences. All pressure setpoints, actual readings, timestamps, and error states are logged in open-format CSV files with nanosecond-precision synchronization. FCS supports Python and MATLAB APIs for custom automation, integration with image acquisition pipelines (e.g., high-speed microscopy), and real-time closed-loop control using external sensor inputs (e.g., flow sensors, pressure transducers). Raw data export enables post-hoc analysis in third-party platforms such as OriginLab, GraphPad Prism, or Python-based scientific stacks (NumPy/Pandas/Matplotlib).

Applications

• Single-cell isolation, sorting, and mechanobiological stimulation under defined shear stress profiles.
• Continuous and pulsatile perfusion in organ-on-chip and tissue-engineered constructs.
• Droplet microfluidics: monodisperse emulsion generation, coalescence control, and sorting based on interfacial tension modulation.
• Microscale chemical synthesis and kinetic reaction monitoring in Lab-on-a-Chip (LoC) and MicroTAS platforms.
• Automated sample preparation for micro-ELISA, nucleic acid extraction, and point-of-care assay development.
• Rheological characterization of complex fluids using pressure-driven flow through calibrated microchannels (e.g., extensional viscosity estimation).
• Fiber-optic sensor calibration and optical trapping setups requiring ultra-stable hydrodynamic confinement.

FAQ

Can the MFCS-EX be used with corrosive or reactive gases such as O₂ or Cl₂?
No. The MFCS-EX is rated exclusively for non-corrosive, non-explosive gases. Exposure to oxidizing, acidic, or halogenated gases will degrade internal elastomeric seals and compromise long-term accuracy and safety.
Is it possible to synchronize pressure output with external hardware triggers?
Yes. The device supports TTL-compatible input/output ports for hardware triggering, enabling deterministic timing alignment with high-speed cameras, laser pulse generators, or electrophysiology amplifiers.
Does the MFCS-EX require recalibration after routine use?
No scheduled recalibration is required under normal operating conditions. However, Fluigent recommends annual verification against NIST-traceable pressure standards for ISO/IEC 17025-compliant laboratories.
Can multiple MFCS-EX units be operated simultaneously from one computer?
Yes. Up to 16 units (128 total channels) can be daisy-chained via USB or managed concurrently via Ethernet using FCS software with appropriate licensing.
What is the maximum recommended tubing length between the MFCS-EX and the microfluidic chip?
For optimal dynamic response, Fluigent specifies ≤1 m of 6 mm OD tubing per channel. Longer lines introduce compliance-induced lag and resonance effects that degrade step-response fidelity.
