Particle Standard Bi-Mix: 10 µm & 25 µm SIS

• Volume: 500 mL
• Standard material: NIST traceable size Polystyrene latex (PSL) spheres
• Nominal sizes and concentrations of standard particles:
  • 10 µm PSL – 1,500 particles/mL
  • 25 µm PSL – 150 particles/mL
• Product batch will be ± 10% of the nominal concentration; individual standard bottles will be certified ± 15% of the mean concentration and particle sizes are certified ± 5% of the standard size (± uncertainty)
• The Certificate of Analysis includes actual concentration testing data and mean size.
