The BD LSRFortessa™ cell analyzer the laboratory is equipped with offers the ultimate in choice for flow cytometry, providing performance and consistency. The system includes a novel collection optics that reduce excitation losses and improve light collection efficiency. The result is optical efficiency that delivers maximal sensitivity and resolution for multicolour applications. An affordable choice to fit most flow cytometry analyzer needs, the BD LSRFortessa™ system has been configured with 4 lasers - blue (488 nm), red (640 nm), violet (405 nm) and UV (355 nm). This enables the detection of up to 13 colors simultaneously. The high throughput sampler (HTS) allows cells to be taken from a 96 or 384 well plate for screening assays.
