Revolutionizing the world of pipetting was never going to be an easy feat, as “extending the volume range of MagPip towards the sub-microliter scale required new methods to determine volumes, as conventional gravimetric methods were no longer sufficient,” confirms Mr. Romer, Hamilton. Now, this leading liquid handling tech supplier has solved this issue by embracing a new vision-based measuring system developed at CSEM. We introduce to you: DropWatch.
An eye on the DropWatch system
“By taking optical measurements of in-flight droplets based on high-speed imaging, DropWatch can record the fast dynamics of droplet dispensing, precisely measure droplet volume, and track 3D trajectories,” explains Peter Cristofolini, Senior R&D Engineer at CSEM. “Using two synchronized cameras positioned at 90 degrees to each other allows us to see each liquid dispensing event with up to 8’000 frames per second. With Hamilton’s powerful software we can reconstruct a high-resolution 3D animation of the droplet shape and its flight path, ensuring MagPip’s extremely accurate droplet volume measurement,” he adds.
