UV-990 Spectrophotometer

Labindia’s UV-990 Spectrophotometer incorporates dual monochromator technology making it well suited to even the most demanding of applications in all areas of UV-Visible Spectroscopy including:
• Pharmaceutical • Material Science • Metrological Verification • Biotechnology • Food Safety – Research
The double monochromator spectrophotometer delivers extremely wide linear dynamic range by ensuring lowest stray light in contrast to a single monochromator system. This type of Instrument is suitable for measurements of highest concentration sample solutions and weak - transmittance materials, such as optical films, coated thin film, semi-conductors, glass, cellulose nanofibre, enzymatic reactions.
