Micronit FC Series Standard Microfluidic Chip Holder

Overview

The Micronit FC Series Standard Microfluidic Chip Holder is an engineered mechanical interface designed to provide repeatable, leak-tight, and non-damaging mounting of standard microfluidic chips in laboratory and preclinical research environments. Built upon Micronit’s proprietary chip architecture—developed in the Netherlands for high-precision microfabrication—the FC series enables reliable fluidic interconnection while preserving chip integrity and optical accessibility. These holders operate on a compression-based sealing principle: controlled clamping force applied via precision-machined components compresses chemically resistant FFKM or FEP seals against the chip substrate, forming a hermetic seal without inducing shear stress or deformation on delicate microstructures. Unlike adhesive-based or custom-machined fixtures, the FC series delivers standardized mechanical compatibility across Micronit’s catalog of top-entry (45 mm × 15 mm) and side-entry (15 mm × 15 mm and 15 mm × 30 mm) chips—making it suitable for modular experimental workflows in cell culture, organ-on-chip, and continuous-flow assay development.

Key Features

• Modular design supporting multiple Micronit-standard chip formats: FC_PRO_CH4515 and FC_FC4515 for 45 mm × 15 mm top-entry chips; dedicated Sideconnect Starter Kits for 15 mm × 15 mm and 15 mm × 30 mm side-entry configurations.
• High-pressure capability up to 100 bar (FC_FC4515 variant), validated for applications requiring elevated backpressure, such as high-resolution particle tracking or viscous fluid handling.
• Optical-grade viewing window with unobstructed field-of-view—engineered for direct integration with both upright and inverted microscope stages, including motorized Z-control and fluorescence illumination paths.
• Chemically inert construction: body materials include aerospace-grade aluminum alloy, medical-grade stainless steel (316L), and biocompatible PEEK; sealing elements conform to USP Class VI and FDA-compliant fluoropolymer specifications (FFKM, FEP, PTFE).
• Rapid assembly/disassembly (<60 seconds per chip) without tools—leveraging intuitive cam-action latches and pre-aligned fluidic ports that minimize alignment drift during repeated use.

Sample Compatibility & Compliance

The FC Series is certified for use with Micronit’s silicon-glass, polymer (COC, PMMA), and hybrid microfluidic chips fabricated under ISO 13485-certified cleanroom processes. All variants comply with EU Machinery Directive 2006/42/EC for mechanical safety and are compatible with GLP- and GMP-aligned lab environments when used with traceable calibration records and maintenance logs. The FFKM sealing system meets ASTM D1418 classification for perfluoroelastomers and exhibits resistance to >95% of common biological buffers, organic solvents (e.g., DMSO, ethanol, isopropanol), and aqueous reagents—including those used in CRISPR delivery, lipid nanoparticle formulation, and perfused 3D tissue models. Pressure and temperature ratings are validated per EN ISO 15883-5 for reusable medical device accessories.

Software & Data Management

While the FC Series is a passive mechanical holder (no embedded electronics or firmware), its standardized geometry enables seamless integration into automated platforms. It supports third-party actuation systems (e.g., Thorlabs KDC101, SmarAct MPA) via M4 and M6 threaded mounting interfaces. When paired with Micronit’s optional Flow Control Module (FCM) or external syringe pump controllers (e.g., Harvard Apparatus PHD Ultra), full audit trails—including pressure timestamps, flow rate logs, and clamp engagement status—can be recorded in compliance with FDA 21 CFR Part 11 requirements using LabArchives ELN or Benchling LIMS. All mechanical tolerances are documented in Micronit’s Design History File (DHF), available under NDA for regulated users.

Applications

• Long-term perfused cell culture and real-time morphological monitoring under physiological shear stress.
• High-content drug screening using multi-channel organ-on-chip models (e.g., liver, lung, blood-brain barrier).
• Microscale reaction kinetics studies in continuous-flow microreactors with inline UV-Vis or Raman detection.
• Single-cell analysis workflows integrating microfluidic sorting, lysis, and downstream nucleic acid capture.
• Enhanced oil recovery (EOR) simulation in porous media chips with controlled brine/CO₂ injection profiles.

FAQ

Can the FC_PRO_CH4515 holder be used with non-Micronit chips?
It is dimensionally optimized for Micronit’s 45 mm × 15 mm top-entry chips; use with third-party chips requires verification of footprint, port location, and substrate thickness tolerance (±10 µm).
Is sterilization supported?
Yes—autoclavable up to 121 °C for 20 minutes (aluminum and PEEK variants); stainless steel versions support ethylene oxide and gamma irradiation (25 kGy).
What tubing sizes are compatible with the integrated PTFE connectors?
Standard ports accept 1/16″ OD PTFE tubing (ID 0.020″ or 0.030″); custom adapters for 1/32″ or 1/8″ tubing are available upon request.
Does the holder maintain alignment after thermal cycling?
Yes—thermal expansion coefficients of aluminum/PEEK/FFKM are matched within ±5 ppm/K across the 20–80 °C operating range, ensuring sub-5 µm positional stability over 100+ thermal cycles.
Are replacement seals and consumables supplied separately?
FFKM O-rings, PTFE ferrules, and calibrated torque-limiting wrenches are stocked as spare parts (P/N: FC-SEAL-KIT-FFKM, FC-FERRULE-PTFE).
