The Abbott Laboratories ADC-500T.M.
The ADC-500T.M. is a second generation differential white cell counter manufactured by Abbott Laboratories which performs a 500-cell differential on both normal and immature white blood cells (leukocytes). It also performs an assessment of red blood cell morphology and estimates platelet sufficiency at a throughput rate of 40 to 50 samples/hr (20,000 to 25,000 cells/hr) in unattended operation. The system consists of (a) a slide spinner for producing a monolayer of blood cells incorporating diffraction pattern sensing to adjust spin time for varying blood viscosities, (b) a stainer/loader which applies stain to the blood film under carefully controlled conditions and which inserts the stained sample slide into a small plastic holder, (c) an encoder which applies a human and instrument readable identification number to each holder and (d) a real-time analyzer which evaluates the sample.
