Specific protein analyzer STS-A200
Part Number:
STS-A200
The STS‑A200 is a high-throughput, fully automated instrument designed for comprehensive protein biomarker analysis in clinical and research settings. It employs turbidimetric scattering rate technology to quantify proteins—such as tumor markers, infectious disease indicators, cardiovascular biomarkers, CRP, and immunoglobulins—by monitoring light scattering of antigen–antibody complexes at multiple wavelengths.
High-Capacity Automation
Delivers up to 180 tests/hour using a 5-position sample rack and automated sample/reagent handling.
Multi-Wavelength Detection
Utilizes a 12V halogen lamp and holographic backscatter grating to support measurements across 8 wavelengths (340–700 nm).
Precision Thermal Control
Maintains reaction cuvettes at 37 ± 0.1 °C for stable kinetic nephelometry.
Smart Quality Management
Features auto-clean, needle blockage alarm, liquid-level detection, reagent monitoring, and quality-control with daily/monthly QC records.
LIS Connectivity & Data Handling
Supports LIS integration via RS‑232, with database backup/restore, automated reporting, and capacity for 100k+ records.
