Used VARIAN 3800 #198088 for sale

VARIAN 3800 is a high-performance double-beam spectrophotometer designed for use with a variety of sample types. It is equipped with an adjustable slit size to optimize resolution, a wide spectral range from 190 nm to 1100 nm, and long-life xenon lamps. The long lamp life is accomplished by multi-pulse xenon flash technology: multiple brief flashes of the lamp are used together to generate a microsecond long exposure. This Xenon Flash technology also provides low detection limits and high sensitivity, allowing for accurate measurement of concentrations as low as parts per trillion (ppt). The user friendly software integrated into 3800 allows for the recording of spectra with a single press of the "Go" button, and automatically stores all settings for the next use. The spectrophotometer also has a built-in spectrum compiler to easily save and retrieve data as well as noise filter algorithms to improve accuracy. In terms of stability, VARIAN 3800 is designed with internal feedback controls for high performance and long-term precision. It is also equipped with an upgraded universal cell holder which can accommodate cells from 10 mm to 50 mm in length. For sample analysis, 3800 features computerized direct linear least squares analysis with pre-recorded or user-defined methods. It can analyze high concentrations with the kinetic mode setting, measure ultra-low concentration with a built-in noise filter, and evaluate the optical density of particles, including nanoparticles, with the Diffusion Analysis Mode. Overall, VARIAN 3800 is a professional-grade medium- to high-resolution double-beam spectrophotometer designed for a wide variety of applications. It offers superior resolution, excellent sensitivity, reliable performance, and easy operation. The cutting-edge Xenon Flash Technology ensures long lamp life; the pre-programmed functions allow for accuracy and convenience; and the advanced cell holder and spectrum compiler offers flexibility.
