The BD LSRFortessa cell analyzer puts the power of the BD LSR platform into a compact footprint. It can easily fit on the benchtop for more cost-effective space utilization. 

The instrument delivers the optimal sensitivity and resolution required for multicolor applications. The BD LSRFortessa cell analyzer can be used to detect up to 18 colors simultaneously and supports up to 4 lasers, and is upgradeable to 7 lasers through the special order program. In addition to the reduced size, design innovations make filters and detectors more accessible for easier setup of new experiments.

Through the BD special order program, customers can upgrade the BD LSRFortessa to support more lasers, choosing from 16 different wavelengths and a wide range of powers. This flexibility allows users to configure the instrument to meet their exact requirements for advanced assay development.


Optics Specifications:

  • Excitation optics
  • Excitation optical platform: The BD LSRFortessa optical layout allows for up to four lasers.
  • Laser Options with Powers
  • 355 nm: 20 mW
  • 405 nm: 50 mW
  • 488 nm: 50 mW
  • 640 nm: 40 mW
  • Optical efficiency: Power loss at flow cell: <20% of specified laser power
  • Flow cell designRectangular quartz cuvette: Internal cross-section, 430 x 180 µm
  • External quartz cuvette surfaces are anti-reflective coated for optimal transmission of laser light.
  • Fixed optical assembly with spatially separated laser beams.
  • Emission optics: 
  • Optical coupling: The quartz cuvette flow cell is gel- coupled by refractive index-matching optical gel to the fluorescence objective lens (1.2 NA) for optimal collection efficiency.
  • Forward scatter detection: Photodiode detector with a 488/10 bandpass filter
  • Side scatter detector: Photomultiplier tube (PMT) with a 488/10 bandpass filter
  • Emission optical design: Emitted light from the gel-coupled cuvette is delivered by fiber optics to the detector arrays. The BD LSRFortessa uses BD’s patented octagon- and trigon-shaped optical pathways that use signal reflection to maximize signal detection. Please see the separate filter guide for information on dye and filter options.
