Safety Data Sheets

Non-Functionalized Colloidal Polystyrene Microspheres
 

  • CV< 5% for microspheres 2 μm ~ 100 μm

  • Roundness > 0.950

  • Sodium azide can be added as an antimicrobial agent upon request.

  • Cross-linked by default with non-cross-linking option available upon request

  • Surface Chemistry
    Carboxyl-terminated or non-functionalized

    Other functional groups available upon request

  • Provided in Milli-Q water with a trace amount of surfactant (<0.1%) that can be easily washed away

  • Concentration available to choose from: 10 - 300 mg/ml (i.e. 1 - 30 % w/v)

  • Can be easily surface-functionalized via chemical bond formation

  • Can be adapted to other common biological buffers like phosphate-buffered saline (PBS) or organic solvents like ethanol via repeated centrifugation and resuspension

  • These polystyrene microparticles might precipitate at the bottom of the containing vial over time, and this is not a sign of aggregation. Large particles precipitate faster than small particles. These particles can be easily resuspended using sonication (ultrasonic bath or ultrasonic homogenizer) or vortexing
