The Cglab560/920 series are open multi-optical-path fluorescence spectrometers, supporting fluorescence emission spectrum scanning and quantitative analysis in the 380–1000 nm range. Standardly equipped with a 390 nm fixed-wavelength light source (near-UV/violet region) for weak excitation of low-cost classic UV dyes such as DAPI and Hoechst, and customizable with 375, 405, 450 nm modules to suit mainstream blue-light dyes like SYBR Green and FAM.
The system measures one standard fluorescence cuvette per run, and supports high-speed network interface for multi-unit cascading and real-time distributed data aggregation.
Applications:
Life Sciences: preliminary screening of cell nuclear fluorescent labels (DAPI/Hoechst weak excitation; 375 nm module recommended for routine detection), enzyme kinetics mechanism studies, near-UV and blue-violet excited probe screening. Protein detection requires specific probes and corresponding excitation modules.
Education & Research: spectral teaching labs, qualitative substance identification, fluorescence quantum yield measurement, quantitative concentration analysis (standard curve method, internal standard method).
Industrial Testing: semi-quantitative analysis of vitamins, tetracycline drug residues, environmental pollutants; fat, chlorophyll (450 nm module recommended for better excitation efficiency), and spoiled food fluorescence discrimination and rapid quality screening.
The system offers open TCP data upload, Python/R/MATLAB/LabVIEW interfaces, built-in Web API and intelligent algorithms, supporting Windows/Ubuntu dual system. Expandable with polarization detection and various optical configurations to broadly meet the needs of teaching, research, life sciences, and industrial testing.
