4. With powerful storage capacity, it can store 2000 data and 96 Linear dispersion.
5. Standard USB interface, WIFI module and Bluetooth module, support wireless Bluetooth printing, optional computer software to manage data, data can be exported through U disk and edited directly by EXCEL.
6. Supports fast scanning (up to 3000nm/min), automatic wavelength and lamp switching settings, and can realize various advanced functions such as wavelength scanning, kinetic measurement, quantitative measurement, and nucleic acid measurement after connecting to computer software.
Principle
The instrument works based on the principle of ultraviolet-visible Spectrophotometric method, spectra-trophotometry. The composite light emitted by the light source is separated by a C-T monochromator composed of blazing Holographic grating, forming monochromatic light to illuminate the sample. The sample absorbs light of a specific wavelength, and the transmitted light is received by the imported silicon photodiode Detector and converted into an electrical signal, which is then converted into a digital signal by the High Accuracy AD chip. Finally, the processor calculates and displays the parameters such as light transmitance or Absorbance of the sample.
Applications
Biochemical analysis, drug testing, environment monitoring, food inspection, teaching and research
Steps
1. Turn it on and warm up, and the instrument self-checks.
2. Set measurement parameters (such as wavelength, mode) through the touch screen.
3. Put in the reference solution and perform Baseline correction or zeroing.
4. Put in the sample to be tested and start the measurement.
5. View, store or export measurement data.
6. Optional with computer software for more complex Light spectrum scanning or dynamic analysis.
Notice
• The instrument should be placed in a stable, non-strong electromagnetic interference, well-ventilated environment.
• Before use, make sure that the instrument is fully preheated to ensure measurement Stability.
• Colorimetric dishes should be kept clean, and the outer wall should be wiped clean after loading the solution.
• When measuring, pay attention to the wavelength range (190~ 1100nm) and photometric range (0~ 200% T, - 0.3-3 A) to avoid exceeding the range.
Before replacing the light source or performing maintenance, be sure to disconnect the power supply.
When exporting data or connecting wirelessly, make sure that the storage device or network environment is safe and reliable.
