The combination of high resolution, low stray light, and an ultrafast scan function with an easy-to-use interface makes this system ideal for R&D and QC laboratories in a variety of fields, such as pharmaceuticals, food science, chemicals, and life sciences, as well as for academic settings.
Resolution of 1 nm -
In addition to achieving a resolution of 1 nm, the highest in its class, by using a monochromator with a Czerny-Turner mounting, the UV-1900i also features a compact, bright optical system.
Ultrafast Scanning -
Spectra can be acquired as fast as 29,000 nm/min, making it possible to acquire high-accuracy spectra in just a few seconds and observe more detailed behavior.
Easy-to-Use Interface -
The UV-1900i Plus on-screen user interface includes large, easy-to-see icons providing a clear picture of the instrument settings on the display. In addition, the large, easy-to-see icons improve intuitive understanding, which enables users to quickly become familiar with the operations.
Navigation Tabs Improve Usability -
In quantitation mode on the UV-1900i Plus, the stages of the entire measurement process and the current status are always shown on the display. As a result, users know immediately what to do in the next step.
Analytical Intelligence -
The system incorporates Analytical Intelligence functions for improved operation. The Assist Function notifies the user when attempting to implement measurements without making necessary corrections, helping to ensure analyses are performed using the correct procedure. By specifying various evaluation criteria for measurement results, the Spectral Evaluation Function enables spectra judgments to be made automatically. The Shutdown/Wakeup Function allows the instrument to be put into sleep mode, limiting power consumption, and be set to wake up automatically at a specified time, enabling analysis to start the instant the user arrives at the laboratory.
The UV-1900i Plus system can also pair with Shimadzu’s software compliance package to provide total data integrity, user administration and audit trails to full compliance with FDA 21 CFR Part 11....

The user-friendly UV-1280 enables intuitive operation, while the enhanced validation, maintenance and inspection functions improve work efficiency. The monitored system for the D2/WI lamps ensures that users can perform highly stable measurements with this compact unit.
Equipped with seven measurement modes, the UV-1280 can be used for a number of measurements, including photometric, spectral, kinetics, DNA/protein, and high-level multi-component quantitation. Modes include: - Photometric mode allows users to measure the absorbance or transmittance at single or multiple wavelengths. It is also capable of quantitation using the k-factor method.
- Spectrum mode records a sample spectrum using wavelength scanning. Users can repeat scans to follow sample changes over time.
- Quantitation mode generates a calibration curve from the measurement of standards and then calculates the concentrations of unknowns. Multi-component quantitation mode quantitates up to eight components mixed in a single sample.
- Kinetics mode measures absorbance changes as a function of time and obtains the enzymatic activity values.
- Time scan mode measures the change in absorbance, transmittance or energy as a function of time.
- Biomethod mode is used to determine DNA and protein concentrations using several quantitation methods, including the Lowry, BCA, Biuret, CBB and UV absorption methods.
Users can connect USB flash drives directly to the UV-1280, making it easy to transport analysis data and to store large amounts of data in a PC. The curve-related data can then be converted to and saved in CSV format.
A wealth of available accessories, including a multi-cell sample compartment and a constant-temperature cell holder, makes the UV-1280 ideal for a wide variety of samples in the pharmaceuticals and life sciences, chemicals, foods and environmental industries.
