BD LSRFortessa™ X-20 Cell Analyzer

The flow cytometer designed for core lab dependability


The BD LSRFortessa™ X-20 Cell Analyzer can be configured with up to 5 lasers to detect up to 20 parameters simultaneously to support ever increasing demands in multicolor flow cytometry. 


BD FACSDiva™ Software controls the efficient setup, acquisition and analysis of flow cytometry data from the BD LSRFortessa™ Workstation. This software is common across BD FACS™ instrument families, including the BD FACSCanto™ Cell Analyzer and BD FACSAria™ Cell Sorter systems. This affords greater application flexibility and allows you to easily move assays from one platform to another.


Take advantage of the multicolor panels designed for various applications, such as immunopheotyping, characterization of stem cells, identification of human mesenchymal stromal cell and more, using the BD LSRFortessa™ X-20 Cell Analyzer.

The BD LSRFortessa™ X-20 System provides optimal resolution of cell populations.


The high sensitivity of the BD LSRFortessa™ X-20 Cell Analyzer allows optimal resolution of lower expression antigens and rare cell subsets. In this example, regulatory T cells (Tregs), characterized by low levels of expression of CD127 and high levels of CD25, were easily identified. Note the resolution of different levels of expression of CD25 and CD127.


Characterization of the BD LSRFortessa™ X-20 Cell Analyzer sensitivity using 8-peak beads


The sensitivity across detectors of a BD LSRFortessa™ X-20 Cell Analyzer equipped with blue (50-mW), red (100-mW) and violet (50-mW) lasers is illustrated by the optimal resolution of SPHERO™ Rainbow 8-Peak Beads. Note that all peaks are easily identified in various detectors from the blue (A, B), red (C, D) and violet (E, F) lasers.
