Features:
1. With SiO2 coating optical mirror, reducing the pollution from outside fully.
2. Adopted high-class grating with wholly hermetic light path design, to ensure the instrument has the super low stray light.
3. With GLP self-check function, check the wavelength accuracy and photometry accuracy.
4. Real-time monitoring the lifetime of Deuterium lamp and Tungsten lamp with advanced system.
5. Wavelength calibration, wavelength setting, change lamp source and dark current calibration automatically.
Basic Functions:
1. Photometry
Test Abs., transmittance and energy by fixed wavelength
2. Quantitative
Linear fit and linear fit through zero two modes.
a. Coefficient, standard sample input and standard Sample read three modes to establish standard curve.
b. Establish A=K1*C+K0, can search original data, graph curve, parameters settings.
c. Can save 240 group curves, can test 240 data in each curve.
d. Double wavelength, Triple wavelength test functions.
3. Kinetics
Used for time course scanning or reaction rate calculations△A/t, can search all data.
4. Multi-Wavelength
Can test Transmittance and Abs. with 8 different wavelengths at most
5. Scanning
User can set the scan range from 190nm to 1100nm to test the max. Abs. peak value, can do derivation, arithmetical operationsto the graph.
6. Biology
6 methods: DNA/Protein, UV, Lowry, BCA,CBB and Biuret
