The Cytomics™ FC 500 is a sophisticated benchtop flow cytometer equipped with the most advanced technologies provided by Beckman Coulter. (Material abstracted from BC brochures)
Lasers
- Air-cooled Argon ion laser, 488nm (20mW output)
- Air-cooled Helium - Neon ion laser, 633nm (20mW output)
- Argon laser beam spot size: 10 microns high by 80 microns wide (elliptical)
- Helium - Neon laser beam spot size: 9.5 microns high by 85 microns wide (elliptical)
Detectors
- Forward Scatter Side scatter detectors are photodiodes
- Five photomultipliers with spectral sensitivity from 185nm-900nm collect the fluorescence signals centered approximatively at:
- FL1 = 525 nm
- FL2 = 575 nm
- FL3 = 620 nm
- FL4 = 675 nm
- FL5 = 755 nm
Flow Rates
- A continuous pressure is applied to the sample tube based on user selected flow rates.
- Three flow rates are available:
- Low (around 15 microl/min)
- Medium (around 30 microl/min)
- High (around 60 microl/min)
Sensitivity - Resolution
- Particle size range: 0.5µm to 40µm diameter
- < 600 MESF for FITC* and APC**
- < 300 MESF for PE*
* measured with Spherotech™ Rainbow Calibration particles and IsoFlow™ Sheath Fluid
** measured with Linear Flow Beads from Molecular Probes
Acquisition Rate
- Maximum acquisition rate: 3,300 events/sec
Sample Handling
- Glass or plastic tubes (12x75 mm)
- Single-tube sampling mode
- Multi Carousel Loader (up to 32 tubes)
Spectral Cytometry
We have also added our own 32 Channel Spectral detector system onto the FC500.
