Large-Pore Filtration Testing

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

Fluid Mechanics Research

SPS100UM-10 can support flow visualization, particle transport, fluid–particle interaction and settling-behavior studies.

Microfluidic Device Testing

The particles may be evaluated for large-channel testing, particle transport, separation research and device performance studies.

Sedimentation and Suspension Studies

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

Cleaning and Contamination Research

SPS100UM-10 may be used for cleaning-process evaluation, contamination-recovery testing and surface inspection studies.

Microplastic Method Development

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

Why Choose 100um Polystyrene Microspheres?

The 100 μm diameter is equal to 0.1 mm, providing easy observation and convenient particle handling.

Typical research areas include:

• Optical imaging

• Particle characterization

• Large-pore filtration

• Flow visualization

• Particle separation

Benefits of 5% Solid Content

SPS100UM-10 is supplied at 5% solids for flexible research and production use.

The concentrated format allows users to prepare different working concentrations. It also supports repeated experiments, pilot testing and larger-volume projects.

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

Standard Polystyrene Surface

SPS100UM-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 carboxyl, amino, fluorescent and colored polystyrene microspheres for specialized applications.
