General description

This polystyrene-based microparticle (size: 20 μm) size standard is ideal for profiling particle size distribution (PSD) of test samples.

Application

Used to standardize and monitor instrument particle size.
Also used:
  • to assess the effect of microplastics on zooplankton upon ingestion[1]
  • to calibrate microfluidic device based on size measurements[2]
  • in focused beam reflectance measurement (FBRM) based particle system characterization[3]

Features and Benefits

  • suitable for routine instrument calibration checks, testing and corrections
  • available in 5 and 10 mL pack sizes as neat samples

Analysis Note

For every lot exact values of particle size and standard deviation are determined with an accuracy of 0.01 μm using a Coulter Multisizer.

Questions

1–2 of 2 Questions  

  1. 1. What is the molecular weight of this product? 2. How many particles are there per mL?

    1 answer

    1. This product is an aqueous suspension containing 10% solids in the form of polystyrene microparticles. The molecular weight of the starting material has not been determined. The particle count is not tested or reported on a lot-to-lot basis. However, historical information reveals an estimate of 2.0 - 2.4 x 10E7 particles/mL. This information is theoretical, based on concentration and particle size.

      Helpful?

  2. We have this 5 mL of latex beads. I curious about how many beads in the bottle. It is important for our study. Thank you. Regards

    1 answer
