Key points

Equipped with a high-precision syringe pump, it delivers stable liquid flow rate and accurate liquid sampling, automatically completing the entire process of sampling, cleaning and detection. It uses high-precision cuvettes for colorimetric testing, featuring strong anti-interference ability, direct concentration reading and accurate test results.
Cuvettes cover all sizes and are compatible with all materials, featuring unrestricted performance and easy replacement. The tube material is continuously upgraded; the core flow path adopts PTFE + 316L stainless steel, and the pump head/valve uses ceramic plungers + wear-resistant coatings.
The test pipelines and cuvettes are cleaned via automatic water washing, rinsing, and air purging. When switching between different samples, residual removal in the pipeline cavity is achieved through solution reverse injection technology, and a pollution-free detection channel is established based on the principle of hydrodynamic displacement.
Standard curves are generated automatically, with faster data fitting. Historical curves can be called with one click, and raw data is stored permanently.
Automatic dilution for over-range samples, one-click testing for high-concentration samples: Data is monitored in real time during detection, and automatic dilution is triggered instantly when concentration exceeds the limit, with no manual intervention required.
Integrates multiple functions including photometric measurement, quantitative analysis, kinetic analysis, wavelength scanning, and nucleic acid/protein detection.
The operating software has 21 CFR function, facilitating users' daily instrument management and ensuring data security. Automatically records testing operation traces.
