2280

Intended Use :

Top of the range Cell Counter for medium-sized laboratories

Features :

• 22 parameters, 2 scattergrams and 2 histograms
• Short sample detection
• Proprietary laser technology, 5 part WBC differential
• Impedance technology for cell counting
• State of the art patented platelet counting technique
• 80 samples per hour
• Sample size flexibility satisfies a wide range of end user requirements

Parameters :

WBC, Lymp#, Neut#, Mono#, Eos#, Baso#, Lymp%, Neut%, Mono%, Eos%, Baso%,
RBC, Hgb, Hct, MCV, MCH, MCHC, RDW,
Plt, MPV, Pct*, PDW*
(* - USA : for research only)
The system also displays :
2 x WBC scattergrams, Plt histogram, RBC histogram

Operation :

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 :

An optional 30 position autosampler is available.
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 WBC differential.

The Plt/RBC channel features the patented "von Behrens" silencer that eliminates RBC recirculation which interferes with low Plt counts in conventional aperture designs.

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.
