Agilent Technologies' Cary 4000 UV-Visible Spectrophotometer

The Cary 4000 is a high performance UV-visible spectrophotometer with excellent photometric performance in the 175-900 nm range, making it a powerful tool for analyzing biotechnology samples with minimal sample preparation. Controlled by the Cary WinUV software, a Windows-based modular software, it can be ordered with specific modules for bio and pharma. The UV-Visible spectrophotometer has a number of optional accessories for liquid samples like temperature control, autosamplers, multicell holders, and sippers.


  • Measure beyond 8.0 absorbance units with reference beam attenuation
  • WinUV software optional modules for bio and pharma
  • Versatile set of accessories including temperature control, liquid and solid sample holders, autosamplers, multicell holders, sippers, and fluorescence
  • Variable slit widths (down to 0.01 nm) for optimum control over data resolution
  • Large sample compartment with precision LockDown mechanism for quick changes of accessories
  • Maximum light throughput using Schwarzchild coupling optics
  • Minimal noise and stray light using a floating aluminum casting and double Littrow monochromator
  • Extended dynamic range by attenuating the reference beam more in line with the sample absorbance
  • Nitrogen pumping separate purging in the sample and monochromator compartments
