Introduction
Double Beam UV-Visible Spectrophotometer is a light intensity measuring unit with deuterium lamp for prevention of ozone inhalation. The SiO2 coated optical mirror enables uninterrupted propagation of light and reduces contamination through external sources. It is characterized with double and triple wavelength test feature for measurement of transmittance and absorbance.
Applications
Used for concentration measurement, photometric analysis, impurities detection in the fields of biology, biochemical, pharmaceutical, environmental science, food, chemical, genetic, quality control, etc.
