High Absorbance level up to 8 Abs.
The double monochromator UV-Vis spectrophotometer UV-2700 has achieved the world's lowest level of stray light (0.00005% at 220nm) and highest efficiency throughput using the unique optical design. The heart of the optical system are the LO-RAY-LIGH® diffraction gratings based on Shimadzu’s new holographic exposure method and optimized etching process, which allows an ultra high absorbance level of 8 Abs. The measurement of high density samples is possible without dilution. For pharmaceutical and other applications requiring hardware validation, the UV-2600/2700 series provides integrated validation software. USP, EP and JP test requirements are supported. A wide range of accessories and software packages are available.
