Applications of 150um Polystyrene Microspheres

Optical Microscopy

The 150 μm particles are easily observed under suitable optical microscopy conditions, supporting particle counting, tracking and morphology studies.

Particle Size Analysis

SPS150UM-10 can be evaluated as a model particle for comparative particle-size testing and analytical method development.

Large-Pore Filtration Testing

The microspheres are suitable for filter-retention, screen testing, membrane challenge and particle-recovery studies.

Fluid Mechanics Research

SPS150UM-10 can support flow visualization, particle transport, fluid–particle interaction and settling-behavior research.

Sedimentation Studies

The controlled particle size supports settling-rate, particle recovery, aggregation and suspension-behavior experiments.

Crystallization Research

The particles may be evaluated as model surfaces in crystallization, nucleation and process-observation studies.

Cleaning and Contamination Studies

SPS150UM-10 may be used for cleaning-process evaluation, contamination-recovery testing and visual inspection research.

Microplastic Method Development

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

Why Choose 150um Polystyrene Microspheres?

The 150 μm diameter equals 0.15 mm, providing convenient handling and optical observation.

Typical research areas include:

• Particle characterization

• Optical imaging

• Large-pore filtration

• Flow visualization

• Sedimentation analysis

Benefits of 5% Solid Content

SPS150UM-10 is supplied at 5% solids for flexible laboratory and production use.

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

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

Standard Polystyrene Surface

SPS150UM-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.

Carboxyl, amino, fluorescent and colored microspheres are also available for specialized applications.
