Hitachi U-5100: Performance and Ecology for Efficient UV-Visible Analysis

The Hitachi U-5100 spectrophotometer combines performance, durability and environmental friendliness. Designed according to the "ECO-FRIENDLY & CLEAN" concept, this device incorporates a low-energy xenon flash lamp, reducing operating costs and environmental impact. The lamp, which emits pulses only during measurements, provides energy savings of 70% compared to previous models, while offering a longer service life, eliminating the need for frequent replacements.

The compact and lightweight design of the U-5100 makes it easy to integrate into laboratories, even where space is limited. With a footprint reduced by 38% and a weight reduced by 52% compared to previous models, it is easy to install and handle. The device is equipped with a dual-beam optical system, ensuring exceptional baseline stability, which is essential for accurate and reliable measurements over long periods of time. This stability is particularly useful for analyses requiring prolonged measurements, where accuracy and repeatability are crucial.

The U-5100's user interface is designed to be intuitive and easy to use. A 6-inch LCD screen clearly displays information, and controls are accessible via a soft-touch keypad, facilitating continuous operations. The system is also equipped with an automatic 6-cell turret, enabling fast and efficient measurements of multiple samples without manual intervention. This feature significantly reduces measurement time, improving laboratory efficiency.

The U-5100 offers a comprehensive range of measurement modes, including photometry, wavelength scanning and time measurement. These modes enable detailed sample analysis, with advanced features such as peak detection, spectrum tracing andaxis expansion. In addition, the system is compatible with PC-based data control and processing software, enabling easy integration into existing laboratory workflows.

In terms of performance, the U-5100 stands out for its low noise level and high sensitivity, thanks to newly developed light detection circuits. These features enable accurate measurements even at low concentrations, which is essential for trace analysis and diluted samples. The system is also equipped with a performance validation function, enabling automatic verification of six performance parameters, thus ensuring data reliability.

The Hitachi U-5100 spectrophotometer is an indispensable tool for modern laboratories, offering a unique combination of performance, durability and environmental friendliness. With its advanced features and compact design, it meets the needs of demanding users while contributing to a more sustainable future.
