Introduction
Double Beam UV-Visible Spectrophotometer features a wavelength range of 190 to 1100 nm, ensuring precise and accurate spectral analysis of samples. It has double beam optical system and uses a 1200 lines/mm diffraction grating for high-resolution spectral separation. It employs an imported silicon photodiode detector for fast and accurate signal conversion. spectrophotometer features a 7-inch color LCD screen for intuitive control and clear display of results.
Applications
Double Beam UV-Visible Spectrophotometer is used for photometric, quantitative, kinetic studies, spectrum scanning, and DNA/protein testing of samples. It is widely used in research laboratories, medical diagnostics, environmental analysis, and food quality control.
