Product catalog summary

Overview: The Evolution is an automated hematology system designed for efficient and precise blood analysis. It supports closed collection tubes and offers a capillary mode that eliminates the need for external pre-dilution. The system can process up to 60 samples per hour and is equipped with a user-friendly interface.

Key Features:

Accepts most closed collection tubes and offers flexibility in sample sizes.
Provides 16 parameters with 3 histograms for comprehensive analysis.
Innovative capillary mode requiring only 25 µL of whole blood.
Data management system capable of storing up to 200 sample records with histograms.

Operation: The Evolution uses electrical resistance for cell counting and sizing, combined with optical absorbance for hemoglobin measurement. It delivers a complete CBC with a 3-part differential in under one minute.

Sample Handling: Blood samples should be collected in EDTA tubes. The required sample sizes are 70 µL for direct mode and 25 µL for capillary mode.

Dilution System: Features a high precision ceramic shear valve and computer-controlled reagent dispenser to maximize performance and minimize downtime. Automatic rinsing prevents carryover and reduces pathogen transmission risk.

Parameter Precision and Linearity:

WBC: CV% < 1.5, range 0.1-99.9 x 10³ cells/µL
RBC: CV% < 1.0, range 0.02-9.99 x 10⁶ cells/µL
Hgb: CV% < 1.0, range 0.0-30 g/dL
MCV: CV% < 1.0, range 40-150 fL
Plt: CV% < 3.0, range 10-1000 x 10³ cells/µL

Reagent Options: Two options are available: EVO-PAC LV for approximately 100 tests and EVO-PAC 200 for approximately 200 tests, depending on lab procedures.

System Software: The software is powerful yet user-friendly, allowing easy access to functions such as counting, result retrieval, QC, calibration, and printing. It includes a 9-digit keypad for patient identification and stores up to 200 results with histograms.

Quality Control and Maintenance: The system includes a comprehensive QC package and provides diagnostic alerts for system operation. A maintenance log is available for monitoring system upkeep.

Evolution Operation System Software Reagent Options The Evolution uses electrical resistance for cell counting (WBC, RBC, Plt) and sizing (Plt, RBC). This is combined with optical absorbance of cyanmethemoglobin for hemoglobin measurement. The technology used combines to give a full CBC with 3 part differential in just under one minute. The Evolution uses powerful but user friendly software. Every operator request such as counting, retrieving results from the memory, QC, calibration, or printing is only a few key strokes away. EVO-PAC LV Users get approximately 100 tests per pack at 5 samples...
