The LSRII, Fortessa, and X-20 appear different, but the operation and workflow are performed in the same manner on all instrument types. Some are also equipped to take the High Throughput Sampler (HTS) for 96 and even 384 well type plates. Analysis occurs at the cuvette flow cell, increasing sensitivity and resolution, allowing detection of 2 relative physical properties as well as up to 18 different colors simultaneously. It can be run at 3 different sample flow rates with a fine-tune adjustor and is capable of analysis rates of up to 40,000 events per second. They are all operated using FACSDiva Software and are available for all labs to use.
The instruments differ slightly in their laser excitation lines, detector capabilities, and whether or not they have an HTS to run plates.
