Laboratory chemical analysis instrument UV Visible spectrophotometer manufacturer
Description:
A spectrophotometer is commonly used for the measurement of transmittance or reflectance of solutions, transparent or opaque solids, such as polished glass, or gases. In chemistry, spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength.
Spectrophotometry is often used in measurements of enzyme activities, determinations of protein concentrations, determinations of enzymatic kinetic constants, and measurements of ligand binding reactions. The use of spectrophotometers spans various scientific fields, such as physics, materials science, chemistry, biochemistry,Chemical Engineering, and molecular biology.
