General description
Micro Particles or Latex Beads, commonly known as polystyrene microparticles, are negatively charged colloidal particles. The microparticles are produced through a polymerization reaction of styrene under controlled conditions. The conducive environment of the reaction induces spontaneous coalescent bead formation. Micro Particles or Latex beads are supplied in aqueous solutions composed of polymer particles with water. Polystyrene′s refractive index at 589 nm is 1.5905 and 1.602 at 486 nm.
Application
Micro Particles or Latex Beads is used for a wide variety of applications like:
- Electron Microscopy.
- Cell Counter Calibration.
- Immunodiagnostics, especially for latex agglutination tests, and
- Phagocytosis Research.
Analysis Note
Für jede Charge werden die exakte Partikelgrösse und die Standardabweichung mit einer Genauigkeit von 0.01 μm unter Verwendung eines Coulter Multisizers bestimmt.

Are the Microparticles based on polystyrene in a suspension sterile? Or is it possible to sterilize the microparticles?
1 answer-
The polystyrene microparticles offered for sale are not sterile.
Although autoclaving is a common method of sterilization, polystyrene microparticles are not autoclavable. Filter sterilization is also not a practical method. There are no protocols available for sterilizing polystyrene microparticles. From the remaining methods for sterilization, it should be possible to either sterilize in 70% ethanol for 30 minutes and then rinse away the ethanol with sterile water. For small batches, UV radiation would be another option.
