What Are Spectrophotometers? 

Spectrophotometers are optical instruments designed to measure the intensity of light absorbed or transmitted by a substance across specific wavelengths. They are critical in analyzing chemical compositions, concentrations, and reactions. By emitting light through a sample and detecting how much light is absorbed or passes through, spectrophotometers provide quantitative and qualitative data about the material. 

These devices are widely used in environmental monitoring to test water or air quality, in pharmaceuticals for analyzing drug formulations, and in the food and beverage industry for quality control. Depending on their design, spectrophotometers can operate in the ultraviolet (UV), visible (Vis), or infrared (IR) light spectrum. Key features often include microvolume sample analysis, scanning capabilities, portability, high-performance optics, and enhanced connectivity options. Advanced models also integrate multimodal functions, fluorescence detection, and compatibility with cloud-based systems, making them versatile for both laboratory and field use. 

GAO Tek’s spectrophotometers offer advanced features tailored to meet the diverse needs of industries, ensuring accurate results, user-friendly interfaces, and compatibility with evolving technologies.
