Application Example
(1) Standard Sample
It is perfectly spherical, has uniform particle size distribution, and provides good reproducibility when measuring particle size distribution.
It is also suitable for particle size comparisons.
- Standard sample for calibration or inspection of particle-size distribution measuring devices, sieves, and filters
- Particles for size comparison during microscopic observation
- Foreign matter sample for quality inspection
(2) Spacer (gap control material)
By mixing glass beads with adhesive, a gap can easily be formed when gluing.
- Spacer for various parts
- Spacer for optical components
- Spacer for electronic components
- Spacer for precision parts
