NB-X8 Double Beam UV-Visible Spectrophotometer
Product features:
1.Photometric measurement: In the range of 190-1100nm, you can choose the single point test wavelength and test method you need to determine the absorbance or transmission of the sample. The concentration of the sample can also be read directly by entering the concentration of the standard sample or the concentration factor.
2.Quantitative measurement: through the curve of known parameter factors or automatically establish a standard solution curve, measure the unknown concentration of sample solution; It has first-order zero crossing, second-order, third-order curve fitting, and single wavelength correction, double wavelength correction, three-point method. Standard curves can be stored and called.
3.Qualitative measurement: A wavelength range is set, intervals are scanned, and then intervals are measured for absorbance, transmittance, reflectivity, and energy of a solid or liquid sample. It can also superimpose, scale, smooth, filter, detect peaks and valleys, save and print the measured graphs.
4.Time measurement: Time measurement, also known as kinetic measurement, scans the sample according to the time range interval of absorbance or transmittance at a set wavelength point, and can also be converted into concentration or reaction rate calculation by entering a concentration factor. Calculation of enzyme kinetic reaction rate. You can also choose from a variety of map processing methods such as superposition, scaling, smoothing, filtering, peak and valley detection, and derivation of the measured maps.
5.DNA/ protein measurement: 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. Multi-wavelength measurement:
6. Multiple wavelength points can be set, and N test wavelengths can be set for the measurement of the absorbance or transmittance of the sample.
7.GLP instrument verification measurement: wavelength accuracy verification, luminosity accuracy verification, stray light verification, and verification results, verification data can be stored, exported, printed.
8.Auxiliary functions: deuterium lamp, tungsten lamp lighting cumulative time, deuterium lamp, tungsten lamp independent off and on, UV light and visible light switching wavelength point selection, operation language selection, wavelength automatic calibration, Bluetooth function.
9.Optional PC counter-control software package functions: quantitative measurement, qualitative measurement, time measurement, DNA protein measurement, multi-wavelength measurement, 3D graphic analysis, map overlay analysis, etc.
