The UV-1900i double-beam spectrophotometer is designed to enhance usability, performance and data compliance. It is an ideal workhorse UV-Vis spectrophotometer for all types of work, from routine analysis to research.

The UV-1900i provides the perfect balance of performance and usability, with high resolution, low stray light, an ultra-fast scan function, and an easy-to-use interface. The spectrophotometer can be operated standalone (without PC) using the touch panel or with a PC with the included LabSolutions UV-Vis software. Measurement modes include photometric, spectrum, quantitation, kinetics, time course and bio-methods. With available microcells, the UV-1900i is also suitable for micro-volume measurement for life science and molecular biology labs. The instrument also packs various features to make everyday work easy and efficient. These include, USB keyboard and barcode input, wake-up functions that enables the device to start up at a desired time, display options for eight languages, network printing, USB printing and expanded memory.

With the included LabSolutions UV-Vis control software, users can get the most out of the instrument in terms of data acquisition, analysis, data integrity and user administration. With the proper software compliance package, the UV-1900i and the software setup can provide total data integrity, user administration and audit trails to fully comply with FDA 21 CFR Part 11 compliance.
