Czerny-Turner spectrophotometer SK-SY15

opticalUV-visiblefor the pharmaceutical industry

Design: the instrument is widely used in medicine and health, clinical testing, biochemistry, environmental protection and other industries, and is one of the analytical instruments reused in physical and chemical laboratories. Used for quantitative or qualitative analysis of substances. Working principle: matter has selective absorption of light, resulting in an absorption effect when exposed to light. Different substances have different absorption spectra, and when monochromatic light passes through a solution, its energy will be weakened due to absorption, and the degree of energy attenuation is proportional to the concentration of the substance. This series of instruments is based on the principle of colorimetry to qualitatively and quantitatively analyze samples, and within a certain concentration range, it conforms to the Lambert-Beer law.
