  • Up to 130 EMIT® tests per hour with three reagents
Reagent system
  • 2 Emit reagent rotors
  • Each rotor has 14 positions for 30 mL bottles and 12 positions for 15 mL bottles, all positions can be assigned as R1, R2 and R3; adapters for 3, 6 and 15 mL bottles
  • Reagent rotor compartment is cooled to approximately 12°C
  • Reagent Volumes:
    • Reagent 1 volume 110-400 μL
    • Reagent 2 volume 0-180 μL
    • Reagent 3 volume 0-180 μL
  • Preheated reagent probes with level detection and integrated mixer
Sample system-providing continuous loading
  • Positive sample identification
  • Sample rotor containing:
    • 80 barcode read samples positions
    • 20 calibrators
    • 10 controls
  • STAT and pediatric functionality
  • Continuous loading
  • Internal barcode reading
  • Primary tubes (13 or 16 mm OD)
  • All positions can contain 5 mL or 10 mL primary tubes or sample cups
  • Sample volume 1-30 μL per test, programmable in steps of 0.1 μL
  • Sample probe with level detection and integrated mixer
Sample predilution (Dual Reagent Mode only) Programmable ratios 1:5, 1:10, 1:20, 1:30, 1:40, 1:50 with 3 possible diluents
