This product contains nominally 30 µm polystyrene particles. The particles are optically transparent rather than opaque under a light microscope. When suspended in water, the difference in refractive index between the particles and water makes the particles clearly visible.

General description
Polystyrene based microparticles (size: 30 μm) are a particle size standard, ideal to determine particle size distribution (PSD) of test samples.
Application
Used for equipment particle size monitoring and validation.
Also used to:
Also used to:
- investigate the impact of polystyrene microplastics on marine biota and organic matter
- study optical confinement in optofluidic laser measurements
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.
