Used CECIL CE 2041 #293605983 for sale

CECIL CE 2041 is a spectrophotometer that is used to measure the intensity of light at a range of wavelengths and to determine the absorbance of a sample on a filter or glass slide. CE 2041 spectrophotometer has a wavelength range of between 250-550 nanometers and an accuracy of 1.5 nm. It is equipped with an optical chopper, a bias light source and a fiber optic probe that can be focused on a small area. It has two detectors, one for the visible light (380nm to 750nm) and one for the near ultraviolet light (200nm to 400nm). The device is compact and easy to use, it can be used in field research and in the laboratory. CECIL CE 2041 measures the degree of light absorption of substances through its two detectors in the visible and ultraviolet range. It consists of a bright xenon lamp that produces very flat output spectrum over the entire wavelength range of 250-550 nanometers. The lamp emission is collected and focused into a single monochromator by a special type of optical chopper. The optical chopper separates the light at each wavelength and directs it to one of the two detectors. The light is then passed through an optical filter that blocks the undesired wavelengths before reaching the detector. CE 2041 is equipped with a digital display and controls for adjusting the integration time, the exposure time and the output gain. The digital display allows the user to quickly read the absorbance of the sample, and the output gain is adjustable for different sensitivities. By using the different exposure times, longer integration times are possible for higher accuracy measurements. CECIL CE 2041 spectrophotometer is accurate, efficient and easy to use. It is suitable for a wide range of applications including the measurement of the absorbance of proteins and other biochemical species, the measurement of the absorbance of thin films and transparent materials, and the measurement of spectral responses in optics and photometry. CE 2041 has a high signal-to-noise ratio and is stable over time and temperature.
