MXR - microfluidic mixer

Introducing the fastest, most adaptable microfluidic mixer in the world.
Speed up your assays, shrink your system, and reduce your assembly costs.

Meet the world’s fastest, most adaptable microfluidic mixer.

MXR stirs up a chamber in seconds. This feat is powered by Redbud Posts, microscopic features that move like tiny stir bars to agitate microliter volumes of fluid. MXR is perfect for 1–100 µL volumes and 0.1 – 1 mm tall chambers.  

This isn’t the first method for microfluidic mixing, but it might be the first you’ll actually use. MXR can rehydrate dried reagents, blend two liquids, or speed up liquid-phase reactions.

MXR enables 10x faster microarray assays

A whole new kind of kinetics

You wouldn’t expect great results from a chemistry lab without a shaker or rotator. Don’t expect to get away with concentration gradients when your assay moves from the bench to a cartridge.

MXR makes any chamber a mixing chamber, with no pumps, bubbles, or vibration. It’s even compatible with optical and electrical sensors. The result is faster reaction kinetics, better analyte utilization, and better analytic consistency.

MXR easily integrates into diagnostic consumables

Make any chamber a mixing chamber

MXR uses a patent-pending modular design that makes adding mixing to your existing cartridge a breeze. MXR won’t constrain the design of your cartridge or instrument, and it might even lower your assembly costs.

Whether your design is based on an injection molded chassis or laser-cut laminates, whether it’s powered by capillary action or pneumatic fluid control, MXR can work with your processes. Zero dead volume, no pumps, and no new tooling tolerances. Just mixing, right where you need it.

Designing cartridges: custom or off-the-shelf?

We recently had the pleasure of collaborating with the talented folks at Fusion Biotec to write a short piece looking at how diagnostics development is changing. Our primary observation: microfluidic technologies are maturing, and that means more pre-built and...

Why we invented MXR

We recently announced our first product, MXR. It's the first microfluidic mixer specifically designed for diagnostic consumables. As anyone who has developed a small-volume assay knows, microfluidic mixing is a universal problem in our industry. Mixing is so obviously...
