The CELL-DYN 3500R automated hematology analyzer employs dual technologies to provide the basis for a five-part WBC differential. Multi-Angle Polarized Scatter Separation (M.A.P.S.S.) provides the primary white blood cell count, all differential information, and reticulocyte analysis, while impedence provides additional information in the presence of fragile lymphocytes and hypotonically resistant red blood cells. The instrument features extended WBC and PLT linearity, RBC and indices corrected for WBC count.

The CELL-DYN 3500R features an automatic start-up cycle designed to prime the flow system and check the background counts. The analyzer also automatically performs a shut-down cycle and places itself in a standby mode.

The CELL-DYN 3500R offers both open and closed sampling options on two instrument versions. Along with the open mode, the SL version includes a dual-head sample loader, which holds up to 100 samples at one time and can process them at up to 90 samples/hour. STATs can be inserted at anytime. The CS version offers single, closed tube sampling along with the open mode. A patient report can be customized to include the following information: patient identification, 22 parameters and a limit sets, color cytograms, color histograms, and manual differential transcription area on a color printout. The 540 MB hard drive provides for on-board storage of 10,000 patient reports. The multi-tasking system permits data editing while samples are being processed.
