BK-D560/BK-D580/BK-D590 DOUBLE BEAM SCANNING UV/VIS SPECTROPHOTOMETER
Features:
●Large LCD screen(480*800) with 65 thousand true color and support U disk data saving
●Imported & Environmental Deuterium lamp, preventing from Ozone inhalation
● Data output: Data can be exported to U disk (USB Output)
●Print port: Instrument can connect PCL printer for printing A4 paper (USB Port)
● Adopted high class grating with wholly hermetic light path design, to ensure the instrument has the super low stray light
●Realtime monitoring the lifetime of Deuterium lamp and Tungsten lamp with advanced system
●Pre-aligned design ensures the user can change lamps conveniently
●With GLP selfcheck function, check the wavelength accuracy and Photometry accuracy, can provide test report and power-off protection
●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 rat 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 operations to the graph.
6, Biology
6 methods: DNA/Protein, UV, Lowry, BCA,CBB and Biuret
