Colorimeter

A photometer is a device that measures the absorbance of light at a specific wavelength, allowing the determination of the concentration of cells, proteins, or other substances in solution. It is widely used in microbiology and biotechnology laboratories, being a practical and economical alternative to the spectrophotometer.

A turbidimeter measures the turbidity of liquids by assessing the scattering of light caused by suspended particles. It is widely used in quality control of water, beverages, and pharmaceutical products.

A fluorometer measures the fluorescence emitted by a substance after being excited by a light source at a specific wavelength. It is highly sensitive and widely used in molecular biology, environmental analysis, and pharmaceuticals.

A densitometer is a device used to measure cell concentration (bacteria and yeast), especially during fermentation processes. It allows for rapid and accurate monitoring of microbial growth, making it an essential tool in microbiology, biotechnology, and quality control laboratories.

A luminometer measures the light emitted by chemical or biological reactions. It is widely used in ATP testing, microbiological control, immunological assays, and cell studies.
