How does a luminometer work
Webmeasured using a luminometer. Luminometers are simple, relatively inexpensive instruments designed to measure sample light output. Light output is measured by … WebOct 19, 2016 · Through a chemical reaction, ATP reacts with luciferase and light is produced. The amount of light can be quantified in a luminometer and the amount of ATP present can then be calculated. Because this reaction happens instantly, the amount of microbiological content can be quantified immediately.
