The Cglab560/920 series are open multi-optical-path fluorescence spectrometers supporting fluorescence emission scanning and quantitative analysis in the 380–1000 nm range. The standard configuration includes a 390 nm fixed-wavelength light source (near-UV/violet region), capable of weakly exciting low-cost classic UV dyes such as DAPI and Hoechst. Optional modules at 375, 405, and 450 nm are available to support mainstream blue-light dyes including SYBR Green and FAM.
The system measures one standard fluorescence cuvette per scan and supports high-speed Ethernet-based multi-unit cascading with real-time distributed data aggregation.
Application Scenarios:
Life Sciences: Preliminary screening of nuclear fluorescence labeling (DAPI/Hoechst weak excitation; a 375 nm module is recommended for routine detection), enzyme kinetics studies, and screening of near-UV/blue-violet excited probes. Protein detection requires specific probes and corresponding excitation modules.
Education & Research: Spectroscopy laboratory teaching, qualitative substance identification, fluorescence quantum yield determination, and quantitative concentration analysis (standard curve and internal standard methods).
Industrial Inspection: Semi-quantitative analysis of vitamins, tetracycline drug residues, and environmental pollutants; fluorescence-based discrimination and rapid quality screening of fats, chlorophyll (a 450 nm module is recommended due to lower excitation efficiency), and spoiled food products.
The system supports TCP-based data uploading, provides Python/R/MATLAB/LabVIEW interfaces, includes a built-in Web API and intelligent algorithms, and is compatible with Windows and Ubuntu. Optional extensions include polarization detection and multiple optical configurations, making it suitable for teaching, research, life sciences, and industrial inspection applications.
