Worth knowing before you order
This is the entry point of the UV-visible range and two figures say so. Stray light is quoted at ≤ 0.3 %T, roughly ten times the 0.03 to 0.05 %T of the double-beam models, and stray light is what sets the highest absorbance you can trust; wavelength accuracy is ± 1 nm. The range also stops at 1000 nm rather than the 1100 nm of the other UV models. Being single beam, it reads blank and sample at different moments, so re-blank often and do not choose it for scanning or kinetics. Spectrum scanning, kinetics and multi-wavelength results are shown through PC software over USB, not on the instrument. The Peltier / sipper system and the multi-cell holder are optional and quoted separately.Specification
