MFI™ gives you more insight into the world of sub-visible particles—way more than just size and count. Because it's image-based, you also get quantifiable morphological parameters for your analysis. Easily differentiate and characterize different particle populations in no time. Plus, MFI has an optic focal length that spans the entire fluidic path, so your sample data is robust and reproducible day in and day out. Add a Bot1 anytime to automate the whole process and kick your throughput up a notch. If you're looking for broader, deeper analysis of your biotherapeutic products, MFI is the particle analysis tool for you.

Detect sub-visible particles

How does MFI work?

Micro-Flow Imaging combines the direct imaging capabilities of digital microscopy with the precise control of microfluidics. What does that get you? High-resolution images with 85% sampling efficiency, more precise counts and sizing with full morphological detail for all sub-visible particles in your sample and the complete confidence that you can accurately identify every possible type, from protein aggregates to air bubbles.

Images of the sample are captured as it passes through the flow cell's sensing zone. Every particle in every image is then analyzed to create a database of particle count, size, transparency and morphology (or shape). And you'll have visual verification on the spot, as images are displayed in real-time. You can also display the results for many samples at once, which makes it easy to monitor stability and comparability.
