Silica & Glass Particle Materials

Separate silica nanoparticle/microsphere requirements from borosilicate/glass particle standards. Material, surface treatment and measurement method matter as much as nominal size.

Material → Measurement Objective

Choose particle material from the method—not from the product name

Material / familyStart here when the requirement is…Quote variables
PSL / polystyrene latexMonodisperse particle-size references, particle-counter/optical calibration, aerosol work, or deposited wafer references.Instrument/application, nominal size(s), form/concentration, quantity, certificate/traceability.
Silica / SiO₂Silica reference behavior, contamination-wafer work, optical/material research, or functionalized silica formulations.Size, surface treatment/functionalization, powder vs suspension, solvent/concentration, quantity.
Borosilicate / glassPowder/particle-size measurement and methods where glass material properties and available size ranges are appropriate.Method/instrument, nominal size/range, quantity, sample preparation and documentation.
Fluorescent / dyed polymerImaging, tracking, optical method development, method visibility or research requiring a colored/fluorescent signal.Size, color/excitation-emission, surface chemistry, dry/suspension form, concentration/quantity.
Functionalized / assay particlesConjugation, binding, lateral-flow, diagnostic or assay-development workflows.Core material, size, functional group/coating, concentration, conjugation target and assay conditions.
Magnetic / metallic nanoparticlesResearch workflows where magnetic response, plasmonic/optical properties or specialized surface chemistry are part of the method.Composition, size, morphology, coating/functionalization, concentration and application.

Make the silica-particle inquiry quote-ready

  1. Instrument, method or end application
  2. Particle material / composition
  3. Nominal size or multi-size set
  4. Dry powder, suspension, concentration or deposited format
  5. Surface treatment or functional group, solvent/dispersion requirements
  6. Package size / quantity and needed date
  7. Certificate, traceability or other documentation requirement

Do not let the catalog make the engineering decision

Applied Physics has overlapping particle families and many individual size SKUs. The correct quote should be driven by the customer's method and required reference properties—not by whichever product title happens to rank first.

For an accurate quote: use the product quote control so the selected product, variation and quantity remain attached to your request.
