The CytoFLEX LX Blue-Red-Violet-Yellow Near UV-Infrared (B-R-V-Y-N-I) Series has the capacity for 23 parameters, including 21 for fluorescence detection. The fully activated instrument includes three channels from the 488 nm (Blue) laser, three from the 638 nm (Red) laser, five from the 405 nm (Violet) laser, five from the 561 nm (Yellow Green), three from the 375 nm (Near UV), and two from the 808 nm (Infrared) laser.

  • Expanded laser color palette provides flexibility to optimize panel design for efficient marker detection
  • Fixed integrated optics and quartz flow cell design enables portability
  • Avalanche Photodiode (APD) detectors provide unmatched red sensitivity and unique compensation workflow
  • Violet Side scatter (VSSC) optional configuration for nanoparticle resolution
