Hi･spheres®

Hi･spheres® is polystyrene particles created using polymerization technology that Polysphere has developed over many years.Can be used as a carrier for latex immunoturbidimetry.

Type

  • PA-series
    Polystyrene for Physical Adsorption
  • CBN plus -series
    Polystyrene for Chemical Bonding

Feature

  • uniform-sized polystyrene latex
  • High dispersibility based on particle design
  • Minimize lot differences by mixing multiple batches
  • Ready to use
  • High characterization capability（Particle size, Surface carboxyl groups）
