Used SHIMADZU 14A #9091829 for sale

SHIMADZU 14A is a powerful spectrophotometer used to measure the absorbance of light over a variety of wavelengths. Specifically, 14A is a double-beam spectrophotometer with an eight-space cell for a wide range of cell sizes. SHIMADZU 14A employs both single and double-beam photometric scanning for accuracy. Single-beam photometric scanning records absorbance data in a single pass, while double-beam records absorbance data in two passes, with one beam used as a baseline and the other used to scan for peaks and valleys in the spectra. The instrument is equipped with a high-efficiency Xenon lamp light source with both UV and visible spectra ranges. The silicon detector array has an exceptionally high sensitivity to accurately detect minute changes in absorbance levels. 14A provides users with enhanced flexibility and convenience with its various measurement modes. The graphically interactive user interface with full-screen displays makes operation easy and efficient. Both manual and automated measurements can be made in absorbance or molar absorptivity (molar absorptance) units. The instrument is calibrated using internal and external standards. The internal standard can be set to one of two pre-defined values, while the external standard can be tailored by using a certified standard that conforms to ISO or ASTM standards. SHIMADZU 14A features a variety of advanced options, including an automatic data logging system, graphical data processing, and automatic peak and valley search and recording. It is equipped with high-speed signal processing capabilities for fast measurements and for convenient analysis of data. Optical parameters can also be adjusted to maximize accuracy and precision, such as the wavelength range, optical sensitivity, lamp wavelength stability, detector wavelength, spectral bandwidth, and optical noise level. 14A not only offers accuracy and convenience, but its automatic data analysis and reporting features have been designed to expand the capabilities of users, allowing for improved test accuracy and providing detailed analysis of spectra results. This makes it an ideal instrument for quality control applications.
