1.4 Reaction System
Reaction disk : Turntable type disk (10-minute reaction per rotation)
Reaction cell : Optical path length 6 mm (area 6 × 5 mm)
No. of reaction cells : 48
Reaction cell control : One rotation + one pitch feed (18 seconds)
Sample pipetting position: One position (fixed)
Reagent pipetting position: One position (fixed)
Reaction temperature : 37 ± 0.1°C (warm water circulating system)
Stirring : By means of stirring rod rotation
Timing for stirring; after each addition of R1,R2,R3
Stirring possible for a minimum volume of 100 µL
Stirring position : One position (fixed)
Reacting solution volume: Minimum; 250 µL (minimum required volume for photometry)
Maximum; 500 µL (temperature control, rinsing upper limit)
Photometric position : One position (fixed)
Cell rinsing : After completion of photometry (rinsing 3 times; rinsing with
detergent not performed)
Carryover evasion : Rinsing for carryover evasion possible; throughput may decrease
by specifying cell carryover evasion
