Introducing the NanoBrook Omni

NanoBrook Omni
Quick Look:


  • • For proteins, peptides, mAb, RNA and other biological samples
  • • 1,000 times more sensitive than other zeta potential techniques
  • • Multimodal & unimodal size distribution software
  • • ISO 13321 and ISO 22412 compliant results
  • • Three measurement angles: 15°, 90°, and 173°



The NanoBrook Omni combines state of the art technology from Brookhaven's particle/protein sizers and zeta potential analyzers in to one powerful and accurate instrument. For particle sizing, it employs a backscattering angle of 173° and the well-established 90° and 15° angles. The zeta potential measurement uses Brookhaven's respected PALS and the classic electrophoresis capabilities. Measure your samples in nearly every possible suspension environment from high salts such as PBS and sea water to organic solvents and of course aqueous solutions!
