Overview

Principal Applications

  • Nanoparticle milling
  • Preparation of ultra-fine nanoparticles
  • Biological cell disruption
  • Improve solubility of small molecules

Advantages

  • Creates nanoparticles less than 100 nm
  • Ultra High Purity
  • Exceptional wear resistance
  • Minimizes contamination
  • Uniform particle size; prevents screen binding
  • Highly efficient
  • Autoclavable / steam sterilizable
  • Scalable
  • Low media density; enables high media loads and agitation speeds
  • Generates less heat than traditional media
  • Biologically inert; prevents chemical reactions and composition changes

Systems

  • AISI 316 stainless steel or other metal alloy agitator bead mills
  • High-speed dispersers
  • Homogenizers
  • Rotor-stators
