The Cary 4000 is a high-end UV-Vis spectrophotometer with excellent photometric performance in the 175–900 nm range, making it a powerful reference spectrophotometer. 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 spectrophotometer has a number of optional accessories for liquid samples, like temperature control and multicell holders. Features Measure beyond 8.0 absorbance units with reference beam attenuation WinUV software—a variety of 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 sample's absorbance Nitrogen pumping—separate purging in the sample and monochromator compartments
