Product Description
NU-8 Double Beam UV/VIS Spectrophotometer
1.Measurement of DNA/protein:
The absorbance is mainly measured at 260nm/280nm/230nm/320nm, and the concentration and ratio of DNA and protein are obtained according to the calculation formula.
2.Auxiliary functions:
cumulative lighting time of deuterium lamp and tungsten lamp, deuterium lamp and tungsten lamp turn off and on independently, UV and visible light switching wavelength point selection, operation language selection (Chinese, English), automatic wavelength calibration, Bluetooth function, etc.
3.Optional PC reverse control software package functions:
quantitative measurement, qualitative measurement, time measurement, DNA protein measurement, multi-wavelength measurement, 3D graphic analysis, map overlay analysis, etc.
Photometric measurement
1.Photometric measurement: In the range of 190-1100nm, you can select the single-point test wavelength and test method you need to measure the absorbance or transmittance of the sample. The concentration of the sample can also be read directly by entering the standard concentration or concentration factor.
2.Quantitative measurement: measure the sample solution of unknown concentration through the curve of the known parameter factor or automatically establish the standard solution curve; with first-order first-order zero-crossing, second-order, third-order curve fitting, and single-wavelength calibration, dual Wavelength calibration and three-point method are optional; standard curve can be stored and recalled.
Qualitative measurement
3.Qualitative measurement: Set a wavelength range, scan interval, and then measure the absorbance, transmittance, reflectivity and energy of solid or liquid samples at intervals. It is also possible to superimpose, zoom, smooth, filter, detect peaks and valleys, save, and print the measured maps.
4.Time measurement: Time measurement is also called kinetic measurement. The sample is scanned according to the time range interval of absorbance or transmittance at the set wavelength point, and the absorbance can also be converted into concentration or reaction rate calculation by inputting the concentration factor. Enzyme kinetic reaction rate calculation.
You can also choose from a variety of spectrum processing methods such as stacking, scaling, smoothing, filtering, peak-valley detection, and derivation of the measured spectrum.
