luminómetro
- The researcher uses a luminometer to measure the light emitted during the chemical reaction.
Examples
-
PHOTO (COLOR): Chemist Andy Gehring inserts a meat sample into a luminometer to check for the presence of bacteria as technician Sue Reed prepares other samples for analysis.
Academic text (2005) -
A luminometer measures the amount of light produced by the reaction of ATP with Bacillus cells and LL by counting the number of light flashes from the photomultiplier tube in the device.
Academic text (2006) -
The method described previously was modified to use direct luminometer readings of the ELISA plates.
Academic text (1997) -
The Filtravette, which retained the bacilli on the surface, was placed into the sample chamber of the luminometer.
Academic text (2006) -
Serum samples were diluted 1 in 2000, and the titres were expressed as the ratio of the luminometer reading to the cut-off value (defined as ten times the negative control mean minus the background control mean for each plate).
Academic text (1997) -
Relative-luminescence units (RLUs) were recorded from the luminometer proportional to the amount of extracellular ATP that originated from the bacteria in a sample (Lee & Deininger, 1999).
Academic text (2006) -
In the laboratory, they calibrated the luminometer to ensure accurate readings of the light intensity.
-
After mixing the samples, the scientist recorded the results on the luminometer to determine the light emissions.

Morphology
luminometer = lumino + meter
The word is compositionally clear as 'lumino' plus '-meter', but both are technical classical forms rather than everyday English morphemes.
Etymology
Luminometer starts with lumin- meaning 'light', like in luminous or illuminate, and ends with -meter meaning 'measure', like in thermometer. So a luminometer is a device that 'measures light', for example the light given off by a chemical or biological reaction.
