Used SHIMADZU DGU-14A #9019262 for sale

SHIMADZU DGU-14A is a light-sensitive, multi-wavelength spectrophotometer typically used for the quantitative measurement of chemical components in liquids. It is a highly accurate instrument that has been designed to meet both the demands of users who are new to ultraviolet and visible light spectrophotometry and advanced researchers alike. DGU-14A features two ultra-violet and four visible light monochromators with a single-mode optical path that ensures maximum accuracy and minimal warm-up errors. Its integration of high speed, multi-wavelength selection allows for measurements to be obtained with extremely low-noise levels. It also includes an automatic wavelength selection feature, providing users with a convenient way to perform multiple wavelength analysis. Light from a tungsten-halogen lamp is dispersed by a diffraction grating and focused on the sample through a sample cell. The wavelength of light that is absorbed by the sample is then read and measured by a highly sensitive photomultiplier tube and an associated linear circuit. The device then calculates absorptivity values for the sample using a set of standard settings, such as reference data, optical path length, scan resolution and speed, and automatically adjusts the values to compensate for changes in spectral output of the lamp or temperature and wavelength drift. The unit stores data points identified by the operator in RAM and can then transfer the data to a printer or other communication device. The system also provides a range of capabilities, including graphical display of measured values, external communication through a 9-pin or RS232C interface, and memory capacity for up to 16 simultaneous measurements, as well as a range of software options. As such, SHIMADZU DGU-14A provides an all-in-one solution for a wide variety of applications, such as chromatography, colorimetry, chemical analysis, bioanalysis, and forensic analysis.
