General description

Silicon dioxide-based microbeads (size: 0.5 μm) are ideal for profiling particle size distribution (PSD) of a particle system.

Application

Used to qualify, validate and monitor particle sizers and surface scanning equipment.
Also used to fabricate silicon-based nano-electro-mechanical systems (NEMS) for mass sensing application.
Silicon dioxide beads, 0.5 μm have a wide range of uses from use as a flow agent to electrical and medical applications.

Features and Benefits

  • suitable for routine instrument calibration checks, testing and corrections
  • available in 5 and 10 mL pack sizes as neat samples
