Product Description:

The DU-5030 model successfully meets the strict requirements of high-precision and high-reliability measurements, suitable for various applications. It can be used in the fields of biological research, biotechnology, drug analysis, pharmaceuticals, academic research, environmental protection, food hygiene, clinical testing, and public health.

Utilizing microcomputer technology and an electronic control system, the traditional optical path structure has been optimized to ensure greater reliability, stability, and durability of the instrument.

The highly automated instrument features automatic diagnostic and calibration recovery functions to ensure stable operation and accurate test data.

Core components use imported parts, all optical mirror surfaces are coated with a SiO2 protective film, and the fully sealed monochromator structure enhances analytical accuracy as well as the stability and lifespan of the instrument. The self-designed plug-in tungsten lamp and deuterium lamp eliminate optical adjustments when replacing lamps, making device setup and maintenance simpler and more convenient.

Instrument Features:

- Chinese main unit operating system, menu display, direct display of spectra, simple, convenient, and fast to use.

- Data storage function: large memory capacity meets daily storage needs for standard curves and experimental data. Supports external USB storage and transfer, allows USB software-controlled printer connection for direct printing of data and spectra, and the test report can be edited and printed.

- Optional configurations based on user requirements include single-cell holder, manual four-cell holder, automatic eight-cell holder, glass holder, 1cm cuvette holder, 5cm cuvette holder, etc.

- Rich measurement methods including wavelength scanning, time scanning, multi-wavelength determination, higher-order derivative determination (optional), dual-wavelength, triple-wavelength (optional), DNA and protein measurement (optional), meeting different customer measurement needs.
