Description

The UVISON UV1901S is a high-precision UV-Vis double beam spectrophotometer engineered for advanced analytical applications in chemistry, biochemistry, environmental science, food testing, and medical diagnostics. It features a wide spectral range of 190–1100nm and variable spectral bandwidths (0.5/1/2/4/5nm), making it highly adaptable for diverse measurement needs. The instrument’s double beam optical system with 1200 lines/mm grating ensures excellent photometric accuracy, repeatability, and stability. Equipped with a large 320×240 mm LCD display, imported silicon photodiode detector, and dual light sources (deuterium & tungsten), the UV1901S delivers robust and accurate measurements with minimal noise. It comes with multiple scanning speeds, auto wavelength setting, and USB/parallel ports for efficient data handling.

Key Features

• The real double beam metering system, with advanced circuit measurement and control system, make the instrument with high reliability and low noise

• Powerful functions like photometric measurement, quantitative measurement, kinetics, spectrum scan, DNA/protein test, multi-wavelength test, etc.

• Plug type deuterium lamp and tungsten lamp transfer lamps without optics debugging

• Large room for samples can hold cuvettes of various specifications

• Auto 8-cell holder is optional.
