  • 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.
