System Specifications:

Data Acquisition:

• Operating principle: analysis of video images
• Sample type: spatial data
• Cell size range: 3 microns to 70 microns

NOTE Although the size range for system performance is 3 microns to 70 microns, the system is capable of detecting particles down to 2 microns.

• Analysis rate: up to 50 Images in 2.5 minutes
• Digitizing resolution: 1.45 mega-pixels

Cell Viability/Concentration/Cell Count

• Concentration Range: 0.5 x 105 to 10 x 106 Cells/mL
• Viability Range: 0 to 100%
• Mean Recovery Value of 20 replicates of Concentration Control on Vi-CELL XR compared to the lot assay value used are ±6%.

NOTE The results for samples at the low end of the concentration range will not be as statistically accurate due to the low number of measured cells. The accuracy at the high end of the concentration range is affected by the difficulty of declustering groups of cells particularly if the cells are large. The sample should be diluted to bring its concentration into range or to improve the accuracy of the
