Durchfluss-Zytometer BD Biosciences FACSMelody

BD Biosciences FACSMelody is a benchtop fluorescence-activated cell sorter designed to bring multi-laser analysis and sorting into a general laboratory space. The instrument nameplate identifies it as a BD FACSMelody Cell Sorter, REF 661936, Model No. 664337, serial number R6643370006, manufactured 2020-10-16, rated 100-240 VAC, 50/60 Hz, 300 W total power, and marked CE and Class 1 Laser Product per IEC/EN 60825-1:2014. The sorter uses a fixed-alignment cuvette flow cell with integrated optics and closed, pressure-driven fluidics. Photos show the open sort chamber with the deflection plates, nozzle assembly and sort collection stage, and the detector compartment with three filter octagons labeled 2 Red, 4 YG and 2 Blue, indicating a three-laser (blue, yellow-green, red) configuration with eight fluorescence detectors plus scatter. A bulk fluid/waste handling module (BD unit) sits on the lower shelf of the instrument cart. The system as photographed includes the FACSMelody sorter, the BD fluidics unit, a Powervar uninterruptible power supply (model ABCE1442-11 / 50144-205R, 120 V, 1440 VA / 1296 W), a JUN-AIR oil-less laboratory air compressor (115 V, 50/60 Hz, 4.8/5.3 A, 4 liter receiver, 2020), a Thermo Scientific HAAKE A10 refrigerated circulator with SC100 controller, a Buffalo Filter Whisper aerosol evacuation system with BD BioSciences HEPA filter, three stainless steel pressurized sheath/fluid tanks (one labeled DI H2O, one still in its shipping carton), and boxes of accessories, tubing, cables, filters and two boxed Buffalo Filter ViroSafe filters. The equipment was photographed in place in a laboratory at a biopharmaceutical facility. The workstation monitor and the chiller display are lit in the photos; no further testing, service history or operating hours are documented.
