Our emphasis is on designing contact-free, continuous monitoring of cell cultures and bacterial fermentations. The developed sensors are capable of monitoring cell density and viability without the need for manual sampling or removing sample culture. This sensor system is also adapted to correlate sensor readings with your company's preferred cell count/sampling method. Skroot sensors are designed to be used with shake flask systems and bioreactors, including SUBs. The Skroot sensor system comprises of three key pieces: a sensor sticker, a reader, and a single-board computer.
