Alpha-1900S double-beam scanning UV-Vis Spectrophotometer is designed by Puyuan Company for the needs of various fields such as organic chemistry, biochemistry, drug analysis, food inspection, medicine and health, environmental protection, life science, etc., using new microcomputer technology And electronic control system, optimize the traditional optical path design and structural design, so that the accuracy, stability and durability of the instrument are more guaranteed while expanding new functions.

Stable and reliable quality:
Deuterium lamps, tungsten lamps, holographic gratings, Detectors and other key components are all imported from world-renowned brands. All optical mirror surfaces are coated with SiO2 protective film, and the fully sealed monochromator structure ensures the stability and reliability of the instrument. long life.
The 20mm thick base ensures that the optical system mounted on it can withstand any strong vibration caused by rough transportation.
The dual-beam dynamic feedback ratio recording photometry system ensures baseline stability.
Highly automated instrument self-diagnosis function and calibration recovery function to ensure the stable operation of the instrument and the accuracy of test data.
Perfect use function:
Choosing an instrument with adjustable bandwidth can select the appropriate bandwidth for different samples and different test requirements, which greatly expands the application range of the instrument and ensures better test accuracy.
Photometric measurement: It is convenient to measure the absorbance and transmittance of samples at specified wavelengths. The multi-wavelength fixed-point test can measure multiple wavelengths at the same time.
Quantitative analysis: automatic establishment of standard curve, optional first-order and first-order zero-crossing linear regression, second-order and third-order curve fitting, optional single-wavelength calibration, dual-wavelength calibration, three-point method for your choice: and can store standards The curve is convenient for future test calls.
Qualitative analysis: The scanning speed reaches 3500nm/min, which greatly improves your work efficiency. The scanning speed is adjustable, the position of the color filter can be fine-tuned, and there are many ways to process the spectrum, including: Graduation, smoothing, filtering, peak and valley detection, etc.
Kinetic analysis: Enzyme kinetic reaction rate calculation. Various spectral processing methods such as zooming, smoothing, filtering, peak and valley detection, and derivation are available for you to choose.
DNA/RNA, protein test function: Built-in special calculation formula, get the final result directly, let you easily enter the field of life science research.
The dedicated PC anti-control workstation connected with the USB data interface has more powerful functions and data processing capabilities. At the same time, PC analyst software with GMP functions can also be selected.
Light source debugging-free function: socket-type deuterium lamp and tungsten lamp, no need for optical debugging when changing the lamp, and the unique automatic light-seeking positioning system makes the debugging and maintenance of the instrument easier and more convenient.
