SCANNING UV VIS VISIBLE SPECTROPHOTOMETER MSP-V1900
* Adopted high-class grating with wholly hermetic light path design, to ensure the instrument has the super low stray light.
* Real-time monitoring of the lifetime of the Deuterium lamp and Tungsten lamp with an advanced system.
* With the 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 are 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
Users can set the scan range from 190nm to 1100nm to test the max. Abs. peak value, can do derivation, and arithmetical operations to the graph.
6, Biology:
6 methods: DNA/Protein, UV, Lowry, BCA, CBB, and Biuret.
