Industrial microfluidics: from Lab-on-a-Chip to Lab-on-a-Manifold

Microfluidic technology has transformed fluid control by enabling the precise handling of small volumes of liquids for research and industrial microfluidic systems. Initially developed as lab-on-a-chip platforms, this innovation introduced miniaturized devices capable of performing chemical analysis, biomedical engineering, and drug discovery tasks in compact setups. However, scaling this technology for industrial production revealed challenges in cost-effectiveness, robustness, and repeatability.

The next step in microfluidic system development has been the lab-on-a-manifold approach, simplifying chip design while relying on external components such as valves, pumps, and sensors for more scalable and automated solutions. This content explores the differences between lab-on-a-chip, chip-in-a-lab, and lab-on-a-manifold, while highlighting their applications in life sciences, diagnostics, and industrial fluid control.

What is Lab-on-a-Chip technology?

A lab-on-a-chip is a miniaturized device designed to integrate laboratory functions such as sample preparation, chemical reactions, and data analysis on a single microfluidic platform. These chips use microchannels as fluid paths and are often fabricated from polydimethylsiloxane (PDMS), silicon, or glass.

Key Features of Lab-on-a-Chip technology:

• Total Analysis System (TAS) with Sample IN, Result OUT capability.
• Used for biomedical research, molecular diagnostics, and chemical analysis.
• Compact design, ideal for droplet-based microfluidics and microfluidic cell culture.
• Enables continuous flow, droplet manipulation, and capillary electrophoresis techniques.

Challenges of Lab-on-a-Chip for industrial use:

• Complex fabrication using micro and nano technologies.
• Fragile PDMS structures with limited pressure control.
• High costs for mass production.
• Difficult to ensure repeatability across large production batches.

What is Chip-in-a-Lab?

The chip-in-a-lab concept simplifies microfluidic systems by using a basic chip design (like a flow cell) combined with external instruments for fluid control. Instead of integrating the full workflow, sample preparation, mixing, and detection occur outside the chip.

Key features of Chip-in-a-Lab:

• Simpler chip designs with fewer microchannels.
• External pumps, valves, and syringe pumps control fluid flow.
• Limited integration of the complete workflow.
• Ideal for rapid prototyping and laboratory testing.

While chip-in-a-lab setups work well in academic and R&D environments, they remain difficult to scale for industrial applications due to manual control requirements and limited automation.

What is Lab-on-a-Manifold?

The lab-on-a-manifold approach builds on the strengths of both lab-on-a-chip and chip-in-a-lab by simplifying chip design while integrating external components for industrial fluid control. A microfluidic manifold replaces complex chip geometries with a modular design where pumps, valves, and sensors manage the fluid flow.

Key features of Lab-on-a-Manifold:

• Simple manifold design paired with external components for flow control.
• Programmable syringe pumps and valves for fluid automation.
• Scalable manufacturing using injection molding or CNC machining.
• Cost-effective for OEM manufacturing.

Why choose Lab-on-a-Manifold for industrial microfluidics?

• Scalability: Easier to manufacture and reproduce for mass production.
• Durability: Machined thermoplastics like PEEK and PMMA for robust operation.
• Customization: Adaptable with modular components and microchannels.
• Cost-effectiveness: Reduces fabrication costs compared to lab-on-a-chip designs.
