Features:
Large LCD screen(480*272 Dots) with 65 thousand true color and support U disk data saving
Imported & Environmental 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 highclass grating with wholly hermetic light path design, to ensure the instrument has the super low stray light
Realtime monitoring the lifetime of 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 protectionWavelength calibration, wavelength setting, change lamp source and dark current calibration automatically
With Si02 coating optical mirror, reducing the pollution from outside fully
Basic Fuctions:
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 calculationsA/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
