EU-2600A UV-Vis Spectrophotometer

Product Introduction

The EU-2600A UV-Vis Spectrophotometer is a single-beam analytical instrument designed for ultraviolet and visible light measurement, quantitative analysis, and wavelength scanning. Covering a wavelength range of 190–1100 nm, it supports transmittance, absorbance, energy, and concentration-related analytical workflows.

Equipped with a high-performance 1200 lines/mm diffraction grating, an imported silicon photodiode detector, and long-life tungsten and deuterium lamps, the EU-2600A is designed for accurate and stable optical measurements. Its 2 nm spectral bandwidth, low stray light, and low baseline drift support demanding routine laboratory applications.

The instrument provides standard-curve analysis, data storage, USB and serial interfaces, and optional PC scanning software for expanded data processing, nucleic acid and protein testing, report generation, and wavelength-scan analysis.

Working Principle

The EU-2600A uses a single-beam optical system with a high-performance diffraction grating to separate light into specific wavelengths. The selected light passes through the sample, and the silicon photodiode detector measures the transmitted optical signal.

The instrument compares sample measurements with an appropriate reference or blank to determine transmittance and absorbance. Quantitative analysis can then be performed using a coefficient method or a standard calibration curve. With optional PC scanning software, the system can also perform wavelength scans and time-dependent measurements for suitable analytical procedures.
