Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7680A #9096287 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7680A is a state-of-the-art spectrophotometer designed for use in a variety of research, diagnostic, and industrial laboratory applications. It is capable of simultaneously measuring up to seven wavelength bands with an optical resolution of 0.01 to 3 nm, and an absorbance range from 0.001 to 999.9 AU. The instrument also offers a wide variety of accessories and peripheral devices to provide even greater versatility. The unit is equipped with a seven-wavelength beam splitter allowing multiple wavelengths to be measured simultaneously. The setting of the beam splitter is controlled by individual switches. For greater precision, the wavelength range can be adjusted from 2 to 4 nm in 0.01 nm increments. The front panel of the instrument features a vacuum-fluorescent display with touchscreen capability for displaying spectral readings and other key functions (wavelength, brightness, etc). All measurements can be entered directly into the unit or downloaded from a PC or external device. In addition, the unit is equipped with a micro-computer interface for controlling data acquisition and analysis. The optical path of the instrument includes a monochromator, a photodetector, and a wavelength selector assembly. The monochromator is a hollow-cathode magnesium lamp/mirror assembly, and the detector is a sterling photocell. The wavelength selector assembly allows the user to change the wavelength from 0.9 to 999 nanometers. All optical components are aligned for optimal performance. In addition to spectrophotometry, HP 7680A is also capable of fluorescence, multi-channel fluorescent analysis, multi-wavelength spectrophotometry, chromatography, and dual-channel spectrophotometry. For sample analysis, the instrument can be fitted with interchangeable accessories such as slit discs, liquid-nitrogen-cooled sample holders, optical extinction filters, high-power light sources, mirror and prism assemblies, and various measuring and vacuum chambers. AGILENT 7680A is an advanced spectrophotometer with a multi-level configuration capable of performing a range of spectrophotometric tests. Its reliability, high resolution, and versatility make it ideal for use in research, diagnostic or industrial laboratories.
