Spectrophotometer
C
Centrifuge
D
Desiccator
Verified step by step guidance1
Understand that a colorimeter is an instrument used to measure the absorbance or transmission of specific wavelengths of light by a solution, which helps determine the concentration of a solute.
Recognize that a spectrophotometer is a more advanced instrument that measures the intensity of light as a function of wavelength, often used interchangeably with colorimeter in laboratory analysis.
Identify that a burette is a device used for dispensing precise volumes of liquid, mainly in titrations, and is not related to measuring light absorbance.
Know that a centrifuge is used to separate components of a mixture based on density by spinning samples at high speed, unrelated to light measurement.
Understand that a desiccator is a container used to keep substances dry by removing moisture, which is also unrelated to measuring light absorbance or colorimetry.
