Shimadzu UV-2550 UV-Vis Spectrophotometer
Shimadzu UV-2550
The Shimadzu UV-2550, with it's double-blazed grating, double monochomator design, provides a high-energy throughput optical system with ultra-low stray light. While featuring low stray light, excellent energy characteristics are provided over an extremely wide wavelength range (200 - 1100 nm), from the ultraviolet to visible, and into the near infrared for both liquid and solid samples.
Use of this instrument is currently determined on a case-by-case basis by the LSBI administration, and it is not available to all LSBI users.  Researchers interested in utilizing this instrument, please send a brief email outlining your intended research needs to the LSBI Director,
Professor Karen Wooley
.  If you are approved to use the instrument, instructions on how to proceed will be sent via email from the LSBI administration.
Low stray light
The UV-2550, with its DDM (double blazed grating, double monochromator) design, provides a high energy throughput optical system with ultra low stray light. The UV-2450, the single monochromator version of the UV-2550, achieves 0.015% stray light even with its simpler optical system.
High Performance
Both instruments offer outstanding cost performance in their ability to provide UV-VIS spectral analysis of wide ranging samples, including organic and inorganic compounds, biological samples like DNA and enzymes, as well as special measurements on optical materials.
Windows XP Pro/2000 Pro Compatible
Operating under the Windows XP Pro/2000 Pro environment, the new generation UV Probe software is provided as standard. UVProbe incorporates the latest multitasking and report generation functionality, including network support, enabling measurement assistance among colleagues and effective presentation of precious data.
Analysis of multiple trace samples
The 8/16 micromulti-cell permits selection among 4 possible combinations with sample capacities of 50mL and 100mL. And, either the normal type or the constant-temperature controlled type cell holder may be selected.
