Product Function

Photometric Measurement: You can select the single-point test wavelength and test method you need in the range of 190-1100nm to determine the absorbance or transmittance of the sample. The concentration of the sample can also be read directly by inputting the standard sample concentration or concentration factor. 2, quantitative measurement: through the known parameter factor curve or automatically establish the standard solution curve, measure the sample solution of unknown concentration.
3. Qualitative measurement: set a wavelength range, scan intervals, and then measure the absorbance, transmittance, reflectance and energy of solid or liquid samples at intervals. The measured atlas can also be superimposed, scaled, smoothed, filtered, peak-valley detected, saved, printed, etc.
4. Time measurement: Time measurement is also called dynamic measurement. The sample is scanned according to the time range interval of absorbance or transmittance at the set wavelength point. The absorbance can also be converted into concentration or reaction rate calculation by inputting the concentration factor.
Enzyme kinetic reaction rate calculation. Can also be measured out of the map overlay, scaling, smoothing, filtering, peak valley detection, derivation and other map processing methods for your choice.
5. DNA/protein measurement: absorbance measurement is mainly carried out at 260nm/280nm/230nm/320nm, and the concentration and ratio of DNA and protein are obtained according to the calculation formula.
6. Multi-wavelength measurement: It is possible to set multiple wavelength points, and measure the absorbance or transmittance of the sample solution. N wavelength test wavelengths can be set to test the absorbance and transmittance ratio at a single wavelength.
7, instrument calibration measurement: built-in special wavelength larger allowable error calibration, transmission larger allowable error measurement, stray light measurement.
8. Auxiliary functions: deuterium lamp, tungsten lamp lighting cumulative time, deuterium lamp, tungsten lamp independent shutdown and startup, ultraviolet and visible light switching wavelength point selection, operating language selection, wavelength automatic calibration, Bluetooth function, etc.
9. Optional PC anti-control software package functions: quantitative measurement, qualitative measurement, time measurement, DNA protein measurement, multi-wavelength measurement, 3D graphics analysis, map overlay analysis, etc.
