Description
Features: 1. Environmental Deuterium lamp, preventing from ozone inhalation. 2. Real-time monitoring the lifetime of Deuterium lamp and Tungsten lamp. 3. Socket-type Deuterium lamp and Tungsten lamp. 4. GLP self-check function: check the wavelength accuracy and photometry accuracy, provide test report and power-off protection. 5. Wavelength calibration, wavelength setting, change lamp source and dark current calibration automatically. 6. SiO2 coating optical mirror, reduces the influence from outside. 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 setting. 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. Technical Parameters:
