4320 Series UV/Visible Spectrophotometer

Zuzi Model 4320 UV Vis Spectrophotometer for High-Precision Analysis

The Zuzi 4320 series UV/Vis spectrophotometers has been developed for laboratories requiring reliable measurements in quality control, research, pharmaceutical, chemical, food, environmental and educational applications. Its single-beam optical system incorporates a 1200 lines/mm holographic grating, a silicon photodiode detector, and tungsten and deuterium light sources to deliver accurate results across the ultraviolet and visible regions of the spectrum.

The 5" colour TFT touchscreen simplifies method set-up and result visualisation. The instrument features internal memory, USB connectivity and an RS232 port for data storage, transfer and integration with other laboratory systems. Its construction combines a cast aluminium base with a high-rigidity housing, ensuring mechanical stability and reliable performance during continuous operation.

Available Versions

The series is available in four configurations to suit different analytical requirements.

Models 4320/1 and 4320/2 operate within a spectral range of 195–1050 nm and are intended for photometric and quantitative analysis. The main difference between these two versions lies in the spectral bandwidth: 4 nm for model 4320/1 and 2 nm for model 4320/2.

Models 4320/3 and 4320/4 extend the spectral range to 190–1100 nm and are designed for photometric, quantitative and spectral analysis. They incorporate spectral analysis functions including spectrum scanning, graphical display of spectral curves and automatic peak detection. These versions are available with a spectral bandwidth of 4 nm (4320/3) or 2 nm (4320/4).

Choosing the Right Model

Versions equipped with a 2 nm spectral bandwidth provide higher spectral resolution than the 4 nm versions, enabling improved separation of closely spaced peaks. Models 4320/3 and 4320/4 extend the working range to 190–1100 nm and incorporate spectrum scanning, graphical display of spectral curves and automatic peak detection functions, providing additional capabilities for advanced analytical applications.
