Standard Plain Polystyrene Surface

SPS15UM-10 has a non-functionalized polystyrene surface without intentionally added carboxyl or amino groups.

The plain hydrophobic surface is suitable for general particle research and passive biomolecule adsorption.

For controlled covalent coupling, SHBC also supplies carboxyl, amino and other functionalized polystyrene microspheres.

Benefits of 5% Solid Content

SPS15UM-10 is supplied at 5% solids for flexible laboratory and production use.

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

Storage and Handling

Store SPS15UM-10 according to the product label, COA and SDS.

Gently mix the suspension before use. Brief sonication may be used when compatible with the application.

Avoid freezing, drying, prolonged high-temperature exposure and contamination. Because larger microspheres may settle during storage, redisperse the suspension thoroughly before sampling.
