Currently available is one analytical FACS machine (Calibur), a modular bench top flow cytometer from Becton Dickinson. The Calibur is an automated, three-color system capable of analyzing a wide variety of reagents; it has been designed for applications that range from routine cell biology to high-throughput analysis. The system includes 488nm and 633nm lasers, four fluorescence and two scatter channels as well as automated high-throughput sampling capability for 96-well plates. Further acquisitions are currently underway.
