1.1 The principle of the spectrophotometer is that the continuous radiation light generated by a light source is decomposed into monochromatic light with continuous wavelength by a dispersion system (monochromator). The monochromatic light is irradiated on the sample pool, and the sample in the pool will be absorbed. By detecting the intensity S of the emitted light and the intensity R of the incident light, the transmittance T=S/R. If the wavelength is continuously adjusted (i.e., scanned), the transmittance of the biochemical sample with respect to the wavelength distribution can be obtained, and its transmittance with respect to the wavelength distribution is dependent on the composition and concentration of the sample. So as to determine the composition of the sample, concentration.
1.2 Spectrophotometers are commonly used for substance identification, purity check, and study of organic molecular structures. In terms of quantification, it can measure the content of components in complex compounds and mixtures, also can measure the dissociation constant of substances, the stability constant of complexes, the end point in molecular weight identification and microtitration of substances, and as a detector in high performance liquid chromatography.

It has the functions of automatic correction of wavelength error and automatic switching of light source. Photometric, quantitative and other functions; With RS232 communication interface optional printer.
BGD 256 Uv-vis Spectrophotometer
2. Characters
1. Advanced electromagnetic force balance force sensor, with high precision, high repeatability characteristics.
2. 5 inch wide touch screen control, current ambient temperature, current tension, peak tension, equivalent tension and other information integration display, the operation is very simple.
3. At the same time design platinum plate, platinum ring two kinds of test methods, can choose one of them, can also choose two kinds at the same time.
4. Automatic operation, eliminate all human error. The platinum plate automatically locks the liquid interface, the platinum ring displays the tension curve, automatically locks the peak tension, without any conversion, and directly displays the tension value on the screen.
5. Full range automatic correction, support weight correction, pure water tension correction, ethanol tension correction.
6. Exquisite ball screw lifting system, no noise, adjustable rising and falling speed.
7. Convenient platinum plate, platinum ring lifting bracket, the user is very easy to uninstall, at any time can use the standard weight calibration force value accuracy.
8. One-button peeling function, the number does not beat, zero no drift.
9. Environmental temperature automatic compensation, water, ethanol as the standard, automatic conversion sample tension value at 20°C.
10. Optional data acquisition software
