BD FACSMelody

Simplify the workflow with smart automation

With BD FACSChorus™ software, researchers are guided throughout the entire cell sorting process using advanced automation technology. Designed to eliminate manual steps, this smart automation simplifies the workflow, making cell sorting easy to learn, and the BD FACSMelody sorter easy to use.


With an intuitive user interface, BD FACSChorus software enables researchers at all skill levels to achieve high-purity sorting with:

  • Screens that are dedicated to each single step
  • On-screen instructions and tips that display when needed
  • Preset data tools to save the user clicks and time
  • Instrument management behind the scenes to activate sort controls, monitor sort progress and turn off sort controls when sorting is completed
  • Simple to read reports

Automation makes sorting simple and saves time

Minimal training required for effective operation

Learning to operate the BD FACSMelody cell sorter is easy, regardless of a user’s skill level or experience. To aid in producing consistent results, BD FACSChorus software prompts novice users with step-by-step instructions. It eliminates the need for setting up the sort streams and monitoring the sort, reducing the risk of poor sort outcomes.


Automation of routine tasks

  • Typically the system is ready in less than 17 minutes, maximizing uptime.
  • Fluidic startup automatically debubbles the stream.
  • Sheath pressure, drop drive frequency and amplitude are optimized.
  • The sort streams are focused and steered into tubes or plates.

Streamlined workflow

  • Instrument settings, gates and sort settings are available and retrievable from saved experiments.
  • Compensation is conveniently computed automatically from the results of compensation controls.
  • Compensation controls can be labeled capture beads, cells, BD™ FC Beads, or a combination of types.
  • Compensation is automatically recalculated when detector settings are adjusted, simplifying operation and saving time.

System anticipates potential issues and identifies root causes

  • Filter/mirror units communicate with the software to confirm the optical configuration supports your experiment.
  • Stream stability is monitored to detect and correct stream aberrations. If the stream cannot be corrected, sorting will pause and the operator is notified.
  • When a sample tube is empty, the sample flow is stopped before bubbles can be introduced into the nozzle.
  • Alerts remind the operator to perform maintenance.
  • Sorting is stopped when the target number of cells is reached, inhibiting overflowing of collection tubes.
