EU-2600D Double Beam UV/VIS Spectrophotometer
Product Introduction
The EU-2600D Double Beam UV/VIS Spectrophotometer is a laboratory analytical instrument designed for accurate ultraviolet and visible light absorption measurements. Its double-beam optical system helps compensate for blank variations and minimize measurement drift, making it suitable for long-term testing and routine laboratory analysis. Equipped with a high-quality holographic grating, a graphic LCD, and automatic wavelength setting, the instrument supports reliable quantitative measurements and standard curve analysis. Optional PC scanning software enables wavelength scanning and expanded data analysis for universities, research institutions, and quality control laboratories.

• Durable Construction: A reinforced baseboard and bracket provide structural stability for routine laboratory use.
Working Principle
The EU-2600D operates on the principle of UV-Visible absorption spectrophotometry. Light from tungsten and deuterium lamps passes through a monochromator equipped with a blazed holographic grating, which separates the light into selected wavelengths. The double-beam optical system measures the sample and reference light paths to help compensate for fluctuations in light intensity and changes in the blank. A silicon photodiode detects the transmitted light, and the instrument calculates absorbance or transmittance based on the measured signals. These results can be used for quantitative analysis, standard curve fitting, and concentration determination.
