The manufacturer of the BD FACSCanto Flow Cytometer is BD. Today's BD FACSCanto system features a fixed-alignment flow cell in the fluidics system that minimizes startup time and improves reproducibility. To increase sensitivity and resolution for each color in a multicolor assay, a patented optical design maximizes signal detection. The optics of the BD FACSCanto system consist of an excitation source with three lasers: blue (488-nm, air-cooled, 20-mW solid state), red (640-nm, 40-mW solid state), and violet (405-nm, 30-mW solid state). Laser excitation optics illuminate cells in the sample, and collection optics direct light scatter and fluorescence signals through spectral filters to the detectors. The pre-owned products will be thoroughly cleaned and fully tested to perform at manufacturer specifications before shipping.
