(* - USA : for research only)
The system also displays :
2 x WBC scattergrams, Plt histogram, RBC histogram
Scientific Principle :
Multi-dimensional optical scattering using stable laser diode light source to optimize the measurement of WBC differential
Electrical resistance for counting (WBC, RBC, Plt) and sizing (Plt,RBC)
Optical absorbance of cyanmethemoglobin for hemoglobin measurement (there is also an optional cyanide-free reagent).
Full CBC with 5 part differential in under one minute.
Sample Volumes :
Blood samples must be collected in EDTA tubes. Depending on how the 2280 is operated, the system requires :
Sample saver mode
|180 µL whole blood
80 µL whole blood
180 µL whole blood
An optional 30 position autosampler is available.
Dilution system :
The Autosampler mixes, reads the barcode, pierces the tube cap and automatically aspirates the sample.
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.
Laser diode illuminated flow cytometer with three, solid state sensors and one PMT tube for
||100 µm dia x 75 µm length
||78 µm dia x 55 µm length
The Plt/RBC channel
features the patented "von Behrens" silencer that eliminates
RBC recirculation which interferes with low Plt counts in conventional aperture
System Software :
The 2280's easy to use software gives rapid access to all patient information including full blood counts, demographics and patient history. QC, calibration and reporting routines are all a few key strokes away.
