The new UV-1900 spectrophotometer integrates a progressive double-beam optical system with Shimadzu’s patented Lo-Ray-Ligh® diffraction grating technology in a Czerny-Turner type monochromator. This technology ensures low stray light with a photometric repeatability previously unknown in its instrument class.

UV-1900 also guarantees maximum efficiency with the industry’s fastest level scan function (29,000 nm/min); measuring in all wavelength regions takes just three seconds. Controlled using an easy-to-handle color touchscreen or the new LabSolutions UV-Vis software, UV-1900 is perfect for optimizing laboratory workflow.

High technologies combine with unprecedented abilities.

Known from high-end models, the Lo-Ray-Ligh® diffraction grating brings the lowest stray light level in its class (less than 0.5 % @ 198 nm) to the UV-1900. It ensures high photometric repeatability with high accuracy, offering one of the largest linearity ranges (see Figure 2).

The UV-1900’s optical system also shows the highest resolution in its class (1 nm), guaranteeing maximum measurement accuracy as Pharmacopeia requires. Moreover, the new ultra-fast scan function enables users to perform accurate measurements with a fantastic scan speed of 29,000 nm/ min. This reduces analysis time significantly and allows the elucidation of fast chemical processes.

Perfect instrument for all analytical challenges

The color touchscreen (controlled by fingertip or included stylus) is accompanied by an intuitive program design. All typical programs (photometric, spectrum, quantitation, kinetics, time-course, and biomethod for DNA or protein quantification) are accessible without needing a PC. The on-board validation and security functions enable full support for Pharmacopoeia, GLP/GMP, FDA, and other regulations. Moreover, the sample compartment accepts common accessories such as the sipper unit, temperature control, and the Specular Reflectance Measurement Attachment.

This qualifies the UV-1900 as the perfect standalone instrument for many application fields such as food, pharma or chemistry. The entire spectral range can be scanned in a matter of seconds. Whereas until now only the intensity at one significant wavelength could be observed for time-course measurements, the absorption spectrum change can now be investigated.

LabSolutions UV-Vis for advanced capabilities

To improve work efficiency by exploiting UV-1900 maximum capacities, the new LabSolutions UV-Vis Software is intended for frequent users of UV-Vis spectrophotometers in various applications.

The clear and simple program layout fits into the LabSolutions family (LabSolutions IR, LabSolutions RF). Easy-to-follow windows and self-explanatory icons optimize system and measurement configuration workflows.


  • Type:UV/Vis
  • Wavelength Range:190 to 1100 nm
  • Optical System:Double beam
  • Scanning Speed:3000 to 2 nm/min, 29000 nm/min when survey scanning
