Project Description

polystyrene-microspheres

EPRUI Biotech provides high quality monodisperse polystyrene beads: crosslinked and non crosslinked polystyrene microspheres for labs or large scale industrial use. The non crosslinked polystyrene microbeads are soluable in solvents such as acetone, chloroform THF, tolune etc. Different with non crosslinked polystyrene spheres, crosslinked polystyrene particles or PS/DVB exhibit much higher physical and chemical stability and are soluable in organic solvents. PS/DVB microbeads have excellent mechanical strength and disperse well in solvents.

  1. Highly uniform particle size
  2. Perfect spherical morphology
  3. Optimized pore structure
  4. Good chemical and PH stability
  5. High mechanical strength
  6. Scale production

Polystyrene beads can be used for a wide range of applications such as : particle size standards, LCD spacers, reverse chromatographic packing media, high end coating, solar battery, medical and biochemical industries etc.
