Why Choose 200nm Polystyrene Microspheres?

The 200 nm diameter provides a practical nanoscale model for optical, membrane, colloidal and biological research.

Compared with irregular particles, spherical polystyrene microspheres offer more consistent geometry for comparative testing and analytical method development.

Typical research areas include:

• Nanoparticle characterization

• Dispersion stability

• Particle aggregation

• Optical scattering

• Surface adsorption

• Membrane filtration

• Particle counting

• Microscopy imaging

Benefits of 5% Solid Content

SPS200-10 is supplied at 5% solids for flexible laboratory and production use.

The concentrated format allows users to prepare different working concentrations while reducing storage and packaging volume. It is suitable for repeated experiments, formulation studies and larger-volume projects.

Standard Plain Polystyrene Surface

SPS200-10 has a standard non-functionalized polystyrene surface without added carboxyl or amino groups.

The hydrophobic polymer surface is suitable for general particle research and physical adsorption studies.

For controlled covalent biomolecule coupling, SHBC can also supply carboxyl, amino and other functionalized polystyrene microspheres.

Standard Microspheres or Certified Size Standards?

SPS200-10 is positioned as a standard plain polystyrene microsphere for research and method development.

It should only be described as a certified or traceable calibration standard when the required certification and traceability documents are supplied for the specific batch.

Customers requiring instrument calibration should confirm particle-size tolerance, CV, measurement method and certification requirements before ordering.
