The ZE5 Cell Analyzer from Bio-Rad Laboratories, Hercules, Calif, is a new flow cytometer with flexible configurations to meet a broad range of experimental complexities and throughput needs. Whether for low-complexity, two-parameter experiments or high-complexity, 28-parameter experiments, the ZE5 is expandable and flexible, accessible for novice users yet powerful enough for experienced flow cytometry professionals. A fully integrated sample loader with the ability to handle tubes or plates without an instrument hardware change enables true walkaway functionality. Features such as a stat tube station, onboard fluidics that are hot-swappable, and automated startup and quality control support continuous operation and maximization of instrument runtime for core labs.
