High powered flow that allows expansion and growth.
Analysis of cells
Bio-Rad's ZE5 is a machine that might not be used to its full capacity initially, but having the ability to grow, add stains, add cell types, add colors, etc. makes it worth its weight. We've added multiple panels since purchasing this machine. The software is fairly intuitive and easy to use making it easy to train new users.
