Semi automatic specific protein analyzer STS-M400
Part Number:
STS-M400
The STS‑M400 is a semi-automated analyzer designed for rapid and sensitive quantification of specific proteins (e.g., tumor markers, infectious disease indicators, cardiovascular markers) in biological fluids like serum, plasma, or whole blood. It uses rate nephelometry, measuring light scattering from antigen–antibody reactions at 650 nm, which offers high sensitivity, fast throughput, and minimal interference from background turbidity .
High Sensitivity & Speed
Conducts 60 tests per hour with minimal background interference through rate nephelometry at 650 nm.
Multiplexed Channels
Equipped with 4 independent reaction cuvettes, enabling simultaneous measurement of multiple assays.
Low Sample & Reagent Use
Requires only 3–5 µL sample and 200–300 µL reagent per test, minimizing volume requirements.
Intelligent Data Management
Includes real-time temperature control, stirring, result storage, printing, and compatibility with LIS systems through RS‑232.
Automated Calibration
Utilizes swappable calibration cards, removing manual curve prep and blanking, while providing traceable results with ≤5% CV.
Robust & Reliable Design
Operates within 15–30 °C and 40–85% humidity, with RS‑232 for printing or LIS linkage.
