Waters 2487 Dual Absorbance UV/Vis Detector

 
Waters 2487 Dual Absorbance UV/Vis Detector
  General Information:

Designed to provide the highest performance in UV/Vis detection for your HPLC analyses, Waters 2487 Dual Absorbance UV/Vis Detector offers the sensitivity required for detection of minor impurities, with the linear dynamic range to simultaneously quantitate major and minor components.

With versatile and easy programmability from the front panel keypad, timesaving qualification derived from the built-in cuvette holder, the ability to view real-time chromatograms or spectral scans via the front panel LCD display, and dual wavelength performance, the detector will enhance the productivity of any chromatography laboratory.
