The Guava PCA-96 System provides automated, higher throughput screening of 96-well microplates or a tray of microcentrifuge tubes. This flexible sample format makes the Guava PCA-96 System ideal for screening in basic research, target validation, assay development, and clinical trials. Like its smaller cousin, the Guava PCA System uses a green laser for excitation, two fluorescence detectors, and a forward scatter detector for assessing relative size. The walkaway automated sampling of 96-well plates makes it easy to screen large numbers of samples and plates in one day.
