Application Example

(1) Standard Sample

With spherical and sharp size distribution, good data reproducibility can be obtained when taking measurement of particle.
Also suitable as size comparison particles.

  1. Standard sample for calibration or inspection of particle size distribution measuring device, sieve, filter
  2. Particles for size comparison during microscopic observation
  3. Foreign matter sample at the time of quality inspection

(2) Spacer ( Gap control material )

By mixing glass beads with the adhesive, easily form a given gap when gluing.

  1. Spacer for various parts
  2. Spacer for optical components
  3. Spacer for electronic components
  4. Spacer for precision parts
