Cary 4000 UV-Visible Spectrophotometer by Agilent Technologies

The Cary 4000 is a high-end UV-Vis spectrometer with excellent photometric performance in the 175–900 nm range, making it a powerful reference spectrometer. The system is ideal for analyzing solid samples or 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-Vis spectrometer has a number of optional accessories for liquid samples, like temperature control and multicell holders.

Cary 4000 UV-Visible Spectrophotometer Features:

• Measure beyond 8.0 absorbance units with reference beam attenuation
• WinUV software—a variety to applications from scanning to kinetics and thermal
• Versatile suite of accessories including temperature control, liquid and solid sample holders, solids autosamplers, multicell holders, and diffuse and specular reflectance accessories
• 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 out-of-plane Littrow monochromator
• Extended dynamic range by attenuating the reference beam to be more equivalent to the samples absorbance
• Nitrogen pumping—separate purging in the sample and monochromator compartments
