Description

BK-UV1900/BK-V1900 SCANNING UV/VIS SPECTROPHOTOMETER Features: ⊙ Adopted high-class grating with wholly hermetic light path design, to ensure the instrument has the super low stray light ⊙Real-time monitoring the lifetime of Deuterium lamp and Tungsten lamp with advanced system ⊙With GLP self-check function, check the wavelength accuracy and Photometry accuracy ⊙Wavelength calibration, wavelength setting, change lamp source and dark current calibration automatically ⊙With Si02 coating optical mirror, reducing the pollution from outside fully 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 Model BK-UV1900 BK-UV1900PC Optical System Single Beam, Grating 1200 lines/mm Wavelength Range 190~1100nm Spectral Bandwidth 2nm Wavelength Accuracy ± 0.5nm Wavelength Repeatability ≤ 0.3nm
