Product Introduction:

The DU-5050 model successfully meets the strict requirements of high-precision and high-reliability measurements. It can satisfy various application needs and can be used in fields such as biological research, bioindustry, drug analysis, pharmaceuticals, educational research, environmental protection, food hygiene, clinical testing, and public health.

By applying microcomputer technology and an electronic control system, the traditional optical path structure design has been optimized, ensuring greater reliability, stability, and durability of the instrument.

The highly automated instrument features automatic diagnostic and calibration recovery functions, ensuring stable operation and accuracy of test data.

All core components use imported parts, and all optical mirror surfaces are coated with a SiO2 protective film. Combined with a fully sealed monochromator structure, this makes analysis more accurate and enhances the instrument's stability and lifespan.

The independently designed plug-in tungsten and deuterium lamps eliminate the need for optical adjustment when changing lamps, making equipment debugging and maintenance simpler and more convenient.

Instrument Features:

The main unit operates with a Chinese-language system. The menu display allows direct display of spectra, making it simple, convenient, and fast to use.

Data storage functions: Large memory capacity meets daily standard curve and experimental data storage requirements. Supports external USB storage and transfer. By connecting a printer via USB through software control, data and spectra can be printed directly, and test reports can be edited and printed.

*Optional accessories according to user requirements include single-cell holder, manual four-cell holder, automatic eight-cell holder, glass holder, 1cm cuvette holder, and 5cm cuvette holder.

Rich measurement methods are provided, including wavelength scanning, time scanning, multi-wavelength determination, higher-order derivative measurement (optional), dual-wavelength, triple-wavelength (optional), and DNA/protein measurement (optional), satisfying varied customer measurement needs.

Measurement requirements such as spectral scanning and time scanning can also be controlled through PC software for more flexible operation.
