KEY FEATURES
Engineered for
Engineered for
high-throughput diagnostics
Independent dual probes, ceramic syringe precision, non-stop reagent cooling, and a Peltier-based reaction system — all in one compact analyzer.
280 Tests/Hour
Constant throughput of 280 tests per hour with mono or double reagent — uninterrupted random access operation.
Precision Ceramic Syringe
Permanent ceramic piston with accurate dispensing as low as 0.1 µL — ensuring maximum precision in sample and reagent handling.
Non-Stop Reagent Cooling
80 reagent positions with Peltier pad cooling system maintaining 2°C–14°C 24 hours a day for optimal reagent stability.
Stable Reaction Temperature
Peltier pad incubation system maintains reaction temperature at 37±0.1°C for stable, accurate results every time.
Advanced Software
Windows-based platform with automatic calibration, Westgard QC rules, multi-point calibration up to 8 points, and LIS integration.
4-Stage Auto Washing
