Duke Standards 3K/4K Series Particle Counter Standards

Thermo Scientific* Duke Standards 3K/4K Series Particle Counter Standards are particle size standards for use in particle counting validation for particle counting instruments.
In comparison with our 3000 and 4000 Series products, this product line is precisely diluted for immediate use in laser particle counters with minimal time-consuming concentration adjustments.
  • NIST* traceable size standards
  • Provide an accurate and convenient method for calibrating or checking performance of laser particle counters used in cleanrooms and other contamination monitoring applications
  • Suspensions of monodisperse polystyrene spheres for use in airborne or liquid particle dispersion systems
  • Particle diameters traceable to the Standard Meter through the National Institute of Standards and Technology (NIST)
  • Particles prepared as low residue aqueous suspensions for minimal background interference
