  • PRODUCT DETAIL

EV-2600RT Split Beam UV/VIS Spectrophotometer

Product Introduction

The EV-2600RT Split Beam UV/VIS Spectrophotometer is a laboratory analytical instrument designed for reliable qualitative and quantitative spectral analysis. Its split-beam ratio-monitoring optical system helps minimize measurement drift, making it suitable for long-duration testing and routine quality control. Covering a wavelength range of 320–1100 nm with a 2.0 nm spectral bandwidth, the instrument supports absorbance, transmittance, and concentration measurements. A 9.7-inch color touchscreen provides intuitive operation and curve display, while automatic wavelength setting, blank measurement, and real-time data storage improve workflow efficiency. Optional PC scanning software enables wavelength scanning and expanded spectral analysis for universities, research institutions, and industrial laboratories.

• Automatic Wavelength Setting: Offers automatic wavelength adjustment with 0.1 nm resolution and automatic blanking.

•  Flexible Curve Fitting: Supports standard curve fitting using single- or dual-wavelength methods.

• Real-Time Data Storage: Saves measurement data and curves for convenient review and reporting.

• High-Quality Optical Components: Uses a 1200-lines/mm blazed holographic grating, silicon photodiode detector, and pre-aligned tungsten and deuterium lamps.

• Convenient Lamp Maintenance: Individual lamp switching and pre-aligned lamp replacement simplify routine maintenance.

•  Optional PC Scanning: Supports wavelength scanning through optional PC software.

• Durable Construction: A reinforced baseboard and bracket provide structural stability for laboratory operation.


Working Principle

The EV-2600RT operates on the principle of UV-Visible spectrophotometry using a split-beam ratio-monitoring optical system. Light from the tungsten or deuterium lamp passes through a monochromator equipped with a blazed holographic grating, which selects the required wavelength. The optical system monitors the light intensity ratio to help compensate for fluctuations and improve measurement stability. A silicon photodiode detects the transmitted light, and the instrument processes the measured signals to calculate absorbance, transmittance, or concentration. The resulting data can be displayed on the touchscreen and used for quantitative analysis, standard curve fitting, and spectral evaluation.
