SK-SY15 UV-Visible Spectrophotometer
Introduction:
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.
Display screen
LCD liquid crystal display screen, measurement data is clear at a glance.
Sample room
Spacious sample chamber that can accommodate 5-100mm cuvettes, improving instrument utilization.
Knob
Wavelength knob, adjust the range of wavelengths.
Cuvette
The ultraviolet region (190-360nm) must use quartz cuvettes.
Features
All key components are configured with imported original parts to ensure the accuracy and precision of measurements; the automatic light gate ensures the service life of the photoelectric sensor and makes instrument testing simpler.
