Used PERSEE T7S #9302794 for sale

The PERKIN ELMER PERSEE T7S spectrophotometer is a modern and versatile analytical instrument designed to measure the absorbance of samples at a wide range of wavelengths, from the UV to near infrared. It uses a xenon lamp as a light source, combined with triple-grating monochromators for excellent wavelength resolution. It includes a selectable 8-Port fiber-optic sampling system to allow for automated studies. The core operation of the PERKIN ELMER T7S spectrophotometer is absorbance measurement. This is accomplished by the separation of the sample light signal into a desired range of wavelengths and then the measurement of the absorbance at each wavelength. This is accomplished by an adjustable photographic lens that focuses the light onto a diffraction grating. The diffraction grating separates the light into its component wavelengths as it passes through, which are then focused onto the sample cell. The absorbance of the sample at each wavelength is then determined by a photodiode detector. The PERKIN ELMER PERSEE T7S has a number of features designed to improve its performance. For instance, it includes an adjustable attenuator that can be used to reduce the intensity of the incoming light thereby allowing for the detection of subtle absorbance changes in a sample. It also includes an adjustable filter wheel that enables the instrument to measure absorbance changes at different optical densities. In addition the PERKIN ELMER T7S is equipped with a range of fiber optic accessories that allow for automated sample runs, such as the 8-port sampling system mentioned earlier. In conclusion, the PERKIN ELMER PERSEE T7S spectrophotometer is an advanced and versatile instrument designed for absorbance measurements at wavelengths from the UV to near infrared. Its range of features and accessories allow for the automation of sample runs and the detection of extremely subtle absorbance changes in samples, making it a valuable tool for a wide range of research and analytical applications.
