SZ - 100 - Nanopartica Series Instruments


The SZ-100 nanopartica series instruments are flexible analytical tools for characterizing the physical properties of small particles. Depending on the configuration and application the system can be used as a particle size analyzer, or also used to measure zeta potential, molecular weight, (MW) and second virial coefficient (A2). Typical applications for the SZ-100 include nanoparticles, colloids, emulsions, and submicron suspensions.


  • A single device analyzes three parameters
  • Two angle system enables analysis of a wide range of high concentration and diluted samples
  • Lowest sample volume
  • Cell design minimizes EOF
