Colored high quality solid glass microspheres
are
manufactured from high pure raw materials (Soda Lime) and have a pure and shining
surfaces. The density colored glass microbeads is 2,45-2.50 g/cm3, chemical composition is
65% SiO2, 13% Na2O, 8% CaO and other minor components. These glass
microbeads are free from lead oxide. The sphericity of these beads ≥
95%. The intense colors result in very high contrast and visibility relative
to most background materials. They are available as dry powders, and can
easily be suspended in aqueous media if desired.
Colored glass microbeads were developed for use
as reference or calibration materials and in applications where a high
visual contrast is desired. The product line consists of a large assortment
of uniform particle sizes between 150 and 2000 microns in eleven different
colors. They can be dispersed in aqueous media and some other solvents.
Currently, we are evaluating the compatibility of various solvents and
dispersion media.
Typical applications of colored glass
microbeads include:
- Reference or calibration materials
- Testing of filtration media and systems
- Vial and container cleaning evaluations
- Flow tracing and fluid mechanics
- Contamination control
- Sedimentation processes
- Calibration of injection devices
- Pharmaceutical manufacturing control
Colored glass microbeads can be observed directly in the media being
tested either visually or by light microscopy. Their high contrast and
visibility make them ideal for contamination control and tracing
applications. |
