Applications of 3um Polystyrene Microspheres
Particle Size Analysis
SPS3UM-10 can be used as a model particle for particle-size measurement, comparative testing and analytical method development.
Particle Counter Research
The uniform particles are suitable for particle-counting studies, detection-method development and instrument-response comparison.
Microscopy Studies
The 3 μm particles provide convenient visibility for optical microscopy, SEM imaging and particle morphology research.
Flow Cytometry Research
SPS3UM-10 can be evaluated for light-scatter studies, flow-system testing and particle detection method development.
Physical Protein Adsorption
The plain polystyrene surface can be evaluated for passive adsorption of antibodies, antigens, proteins and other biomolecules.
Latex Agglutination Assays
The particles may be used as carriers for latex agglutination reagent and particle-based immunoassay development.
Phagocytosis and Cell Uptake Studies
SPS3UM-10 can be evaluated as a model polymer particle for phagocytosis, cellular uptake and particle–cell interaction research.
Microfluidic Research
The microspheres are suitable for flow visualization, channel evaluation, particle transport and separation studies.
Filtration and Membrane Testing
The particles can support filter-retention, membrane-efficiency, particle-recovery and separation research.
Colloid and Sedimentation Studies
SPS3UM-10 can be used to study suspension behavior, particle aggregation, sedimentation and surface interactions.
Why Choose 3um Polystyrene Microspheres?
The 3 μm diameter provides convenient optical detection and controlled microscale particle behavior.
Typical research areas include:
Particle characterization
Particle counting
Protein adsorption
Latex agglutination
Flow-system testing
Cell uptake studies
Microfluidic transport
Microscopy imaging
Standard Plain Polystyrene Surface
SPS3UM-10 has a non-functionalized polystyrene surface without added carboxyl or amino groups.
The 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
The 5% solids format provides flexibility for research and production use.
Users can dilute the dispersion to the required working concentration while supporting repeated testing, assay development and larger-volume projects.
Standard Microspheres or Certified Size Standards?
SPS3UM-10 is positioned as a standard plain polystyrene microsphere for research and method development.
It should only be described as a certified or traceable particle-size standard when corresponding certification documents are supplied for the specific batch.
Customers requiring calibration materials should confirm particle-size tolerance, CV, testing method and traceability requirements before ordering.
