Worth knowing before you order
Single beam: the blank and the sample are read at different moments, so lamp drift lands in the result — re-blank often, and choose a double-beam instrument for scanning or kinetics. Wavelength accuracy here is ± 0.8 nm against ± 0.3 nm on the double-beam models, which matters for any identification test that turns on a peak position; check the tolerance your method allows. Spectrum scanning, kinetics and multi-wavelength results are displayed through the PC software over USB, not on the instrument. The larger cuvette holders that make use of the 5 to 100 mm compartment are optional, as are the Peltier / sipper system and the multi-cell holder; none is included. The baseline flatness row is printed as ± 0.002 A/h, a drift unit rather than a flatness unit, so it has been left out.Specification
