What is the effect of the wavelength on the spectrophotometric measurements of protein? Does the wavelength setting affect the absorbance reading of a spectrophotometer? For example, if I am using a spectrophotometer ...
In addendum, keeping the wavelength around the absorption maximum for the light-attenuating species avoids introducing error into Beer's Law. There are limitations to the law, outlined here where we can see that around the lambda max, there's little change in absorption per unit wavelength: ![enter ...

What are the requirements for a spectrometer to be used in biological research? Suppose one would do spectrophotometry on biological materials. What would be the minimum requirements for the measuring device so that t...
For all the common uses of a spectrophotometer in biology, any commercial one should be sufficient. For all the routine stuff, the quality of the spectrophotometer is usually of negligible importance.
