Descrição

Descrição geral

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.

Aplicação

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.

Nota de análise

For every lot exact values of particle size and standard deviation are determined with an accuracy of 0.01 μm using a Coulter Multisizer.
