Applications of 200um Polystyrene Microspheres

Optical Microscopy

The 200 μm particles are easily observed under suitable optical microscopy conditions, supporting particle counting, tracking and morphology studies.

Large-Pore Filtration Testing

SPS200UM-10 can be evaluated for screen testing, filter retention, membrane challenge and particle-recovery studies.

Fluid Mechanics Research

The microspheres support flow visualization, particle transport, fluid–particle interaction and hydrodynamic research.

Sedimentation Studies

The controlled particle diameter is suitable for settling-rate, suspension behavior, aggregation and particle-recovery experiments.

Crystallization and Nucleation Research

SPS200UM-10 may be evaluated as a model particle or surface in crystallization, nucleation and process-observation studies.

Particle Separation Studies

The microspheres can support sieving, classification, particle recovery and separation-method development.

Cleaning and Contamination Research

SPS200UM-10 may be used for cleaning-process evaluation, visible contamination studies and particle-recovery testing.

Microplastic Method Development

The particles can be evaluated as a defined polystyrene model for environmental sampling, separation, transport and recovery studies.

Why Choose 200um Polystyrene Microspheres?

The 200 μm diameter equals 0.2 mm, providing convenient handling and observation.

Typical research areas include:

• Optical imaging

• Particle characterization

• Large-pore filtration

• Flow visualization

Benefits of 5% Solid Content

SPS200UM-10 is supplied at 5% solids for flexible laboratory and production use.

The concentrated suspension can be diluted to different working concentrations and supports repeated experiments, pilot testing and larger-volume projects.

The liquid format reduces weighing and initial dispersion steps compared with dry microspheres.

Standard Polystyrene Surface

SPS200UM-10 has a standard plain polystyrene surface without intentionally added fluorescent dyes or reactive functional groups.

It is suitable for general particle, filtration and surface-interaction research.

SHBC also supplies functionalized, fluorescent and colored polystyrene microspheres for specialized applications.
