A Double Beam UV-visible Spectrophotometer is an analytical instrument used to measure the absorbance or transmission of light by a sample in the ultraviolet (UV) and visible regions of the electromagnetic spectrum (typically 190–1100 nm). It employs two light beams—one passing through the sample and the other through a reference—to provide accurate and precise measurements by compensating for variations in light source intensity and other instrumental factors.
Accumax India Double Beam UV-Visible Spectrophotometer is a powerful tool for precise and reliable spectroscopic analysis, offering superior performance over single beam systems due to its dual-beam design. Its versatility, high accuracy, and advanced features make it indispensable in pharmaceuticals, biotechnology, environmental monitoring, and research. When selecting a model, consider application needs, sample types, and budget, as the higher cost and complexity may not be necessary for routine analyses where a single beam system suffices.
