Olis CLARiTY series Request More Information

With a CLARiTY UV/Vis, you can work in the native, natural environments for conclusions that will stand the test of time.

  • Living cells
  • Living tissue
  • Nanoparticles
  • Micro-particles
  • Frozen samples
  • Aggregating proteins, and
  • All light scattering samples.

Unique to the CLARiTY line:

  • Immunity to scatter throughout the UV/Vis spectral range
  • Useful with suspensions, solids, and solutions
  • Pathlengths of 20 or 30 centimeters using 4 or 8 mL sample holders
  • Available millisecond spectral scan rate

 

Integrating sphere and dual wavelength technologies get you close. But the CLARiTY "is an almost incredible advance on the best Britton Chance was ever able to do for turbid suspensions:

How does it work?

In ordinary UV/Vis spectrometers, a focused beam of light shoots through the sample to an awaiting detector. If the sample is particulate, some or much of this focused measurement beam is scattered out of the detection path. The instrument can only return an 'apparent high absorbance’ reading.

In the CLARiTY, the measurement beam is a "gas of photons." Because the measurement beam is fully diffuse, it cannot be scattered further by a light scattering sample. The only way the light is changed before and after the sample is by being absorbed by the sample.

Thus, scatter does not matter, only sample absorbance does.

The Olis CLARiTY series will have extraordinary consequences in the fields of mitochondria and cancer cells, Alzheimer's, Parkinson's, lupus and other diseases, polymer and nanoparticle development, and many other contemporary studies.

MODELS

Olis CLARiTY 1000
CLARiTY1000

The CLARiTY 1000 combines the innovative CLARiTY performance with the unbeatable speed and sensitivity of the Olis RSM 1000 rapid-scanning spectrophotometer. Choose this model when you want

  • Highest speed (≤ 100 scans/ second) spectral scanning
  • Utility in alternative measurements such as stopped-flow and CD (≤ 1000 scans/ second)
  • Spectral ranges of 170-540 nm, 200-800 nm, 400-1100 nm, or 800-1700 nm, including the option of all three ranges with minor hardware exchanges

"The ability to conduct direct spectrophotometric studies under noninvasive physiological conditions represents a new and powerful approach to examine the extents and rates of biological events in situ without disrupting the complexity of the live cellular environment." RC Blake II, owner of the first Olis CLARiTY 1000. See more at http://www.orau.gov/gtl2012/abstracts/blake01.pdf

Also available on non-rapid scanning models

CLARiTY 620
CLARiTY 620

The CLARiTY 620 is a tiny, non-rapid scanning version of the 1000. Choose this model when

  • Your sample is static or very slow to change
  • Utility in alternative measurements such as CD
  • Spectral range of 170-700 nm, 400-1100 nm, or 800-1700 nm

CLARiTY 17
CLARiTY17

The CLARiTY 17 employs the world-class Cary 14/17 prism + grating monochromator. The DSPCs replace the old style cuvette holders. Choose this model when

  • Your sample is static or very slow to change
  • Utility in alternative measurements such as CD
  • Sub-nanometer spectral resolution, to 0.1 nm
  • Spectral range within 185-2600 nm
