Double Beam UV/Vis Spectrophotometer

Features:

Environmental Deuterium lamp, preventing from Ozone inhalation.
Real-time monitoring the lifetime of Deuterium lamp and Tungsten lamp.
Socket-Type Deuterium lamp and Tungsten lamp.
GLP self-check function: check the wavelength accuracy and Photometry accuracy provide test report and power-off protection.
Wavelength calibration, wavelength setting, change lamp source and dark current calibration automatically.
Si02 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

Coefficient, Standard Sample input and Standard Sample read three modes to establish standard curve
Establish A=K1*C+K0, can search original data, graph curve, parameters settings
Can save 240 group curves, can test 240 data in each curve
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, Arithmetical operations to the graph.

6, Biology:

6 methods: DNA/Protein, UV, Lowry, BCA, CBB and Biuret
