A blank is used in order to cancel out or zero the absorbance of all the other components in the sample except the component whose absorbance is to be measured. For example, if you want to measure the absorbance of a solute in water, you will use only water as a blank and the spectrophotometer will subtract the absorbance of water from the spectrum when you measure the absorbance of your solute in water.

Where can I get a Spectrophotometer fixed in Southwest Florida?
Currently, there are no places that are in FL that can fix them, however, you can call the number on the back of the Spectrophotometer & they can assist you.
Can a spectrophotometer be used to diagnose diabetes?
no
How would a spectrophotometer be used in treating diabetes?
A spectrophotometer is not and could not be used to treat diabetes. This is a device that measures light in a specific wavelength.
Function of the spectrophotometer?
The spectrophotometer is an instrument that measures the amount of light of a specified wavelength which passes through a medium. This instrument operates by passing a beam of light through a sample and measuring the intensity of light reaching a detector.
How do you work spectrophotometer?
. A spectrophotometer is a photometer (a device for measuring light intensity) that can measure intensity as a function of the color, or more specifically, the wavelength of light
What do you use to view light spectrums?
A Spectrophotometer
