Shimadzu, specialists in analytical instrumentation and testing equipment, introduces the updated UV-1900i Plus UV-Vis Spectrophotometer, an evolution of its popular compact UV-Vis system. The updated version incorporates targeted improvements in both hardware and software. The result is a high-speed, high-sensitivity system that supports efficient workflows in pharmaceutical, life science, chemical, and food laboratories. In addition to the standard LabSolutions UV-Vis software, Shimadzu also offers LabSolutions DB UV-Vis and CS UV-Vis to support compliance with electronic record and signature (ER/ES) regulations.
Easy-to-use interface
The UV-1900i Plus is equipped with a modern on-screen interface featuring bold, high-contrast icons on a dark background, allowing users to navigate settings with ease and confidence. This intuitive design minimises operational steps and shortens the learning curve, enabling users to become proficient quickly. A next-generation CPU enhances responsiveness, ensuring smooth and efficient operation. Trusted by laboratories around the world, the UV-1900 series is renowned for its robust design and long-lasting performance in both routine and high-precision UV-Vis analysis.
Reasons to choose UV-1900i Plus:
- Improved performance with enhanced optics and CPU
The hardware platform ensures higher sensitivity and reduced noise levels compared to previous models, enabling precise detection even at trace concentrations. Full spectral scans can now be completed in under seven seconds, thanks to scanning speeds reaching up to 29,000 nm/min. - Shutdown/wakeup function
A highlight of the UV-1900i Plus is its integrated shutdown and wake-up functionality, allowing the instrument to enter sleep mode after use and power up automatically before the lab day begins. Combined with the startup validation function, this ensures the system is ready to measure upon arrival, minimising downtime and improving sustainability. - Smart assist functions and intuitive user interface
To support users of all experience levels, the instrument includes an assist function that verifies baseline, auto-zero, and blank corrections before each run. The large icon-based touch-screen interface is designed for ease of use, reducing the number of steps required during operation and making instrument status clear at a glance. - User-friendly connectivity and input
Designed with convenience in mind, the UV-1900i Plus allows seamless data transfer via network and supports wireless printing from multiple instruments. For faster and error-free sample handling, users can input sample names and values directly using a barcode reader or keyboard—making routine workflows smoother and more intuitive.
In addition to these features, the UV-1900i Plus offers flexible software integration. The system can be operated stand-alone or with LabSolutions UV, DB, or CS software. Quantitative data analysis functions have been expanded to include automatic pass/fail determination, range validation, and colour evaluation via the Hazen (Yellowness) scale—supporting material inspection in regulated environments.
Engineered to meet the requirements of JP, USP, and EP standards, the UV-1900i Plus features a compact Czerny-Turner monochromator with 1 nm resolution. Its photometric repeatability of 0.0002 Abs (at 0.5 and 1.0 Abs) ensures consistent, high-quality results. Built for reliability, fast performance and ease of use, the UV-1900i Plus is a dependable workhorse for laboratories seeking performance, simplicity, and longevity.
