Drew Scientific Excell 22 - 5 part diff Hematology Analyzer

Features :
•	22 parameters, 2 scattergrams and 2 histograms
•	Proprietary laser technology, 5 part differential
•	Impedance technology for cell counting
•	State of the art patented platelet counting technique
•	70 samples per hour
•	Sample size flexibility satisfies a wide range of end user requirements
•	SVGA color monitor with scattergrams and histograms on screen
•	User friendly operator interface (keyboard and mouse)
•	Data management stores up to 100,000 sample records including scattergrams and histograms
•	Built in QC package (Levey-Jennings, X-B)
•	Bidirectional port for communications with LIS
•	Modern electronics with industrial grade processors for durability and serviceability
Optional Features :
•	Automatic 30 tube sampler/mixer with optional bar code sample identification (as shown)

Parameters :
	WBC, Lymp#, Gran#, Mono#, Eos#, Baso#, Lymp%, Gran%, Mono%, Eos%, Baso%, RBC, Hgb, Hct, MCV, MCH, MCHC, RDW, Plt, MPV, 2 x WBC scattergrams Plt histogram, RBC histogram
Principle :
	4 x dimensions optical scattering for WBC differential Electrical resistance for counting (WBC, RBC, Plt) and sizing (Plt, RBC) Optical absorbance of cyanmethemaglobin for hemaglobin
Sample volumes :
	Direct mode Sample saver mode Automatic sampler	180 µL whole blood 80 µL whole blood 180 µL whole blood
Dilution System :
	High precision ceramic shear valve and computer controlled diluent dispenser. Automatic rinse inside and outside of the sample probe prevents carryover and reduces risk of transmission of blood borne pathogen to operators.
Sensors :
	Flow cytometer with solid state sensors or photomultiplier for WBC differential.
	WBC aperture	100 µm dia x 75 µm length
	RBC/Plt aperture	78 µm dia x 55 µm length
	The Plt/RBC channel features the patented "von Behrens" silencer, which eliminates RBC recirculation that interferes with low Plt counts in conventional aperture designs.
Throughput :
	Minimum 70 samples per hour in direct mode.
