Calculating microspheres per gram
During scientific experiment design and analysis it is common to need to know the number of spheres per gram of dry material. We have put together the table below to help speed up the process.

Silica nanoparticles and nanospheres are now available in distributions of less than 10% CV in the sizes of 0.25 micron, 0.5micron, 0.75 micron, 1.0 micron, 4 micron and 8 micron.
Scientists who study fish require artificial micro-particles to simulate fish eggs and their behavior in water. In order to accurately simulate the fish eggs it is important to use particles of the proper size and buoyancy/density. Particles with accurate size ranges and densities are now available.
Spacer Grade Glass Microspheres are presently used in gas plasma displays, automotive mirrors, electronic displays, flip chip technology, filters, sporting goods equipment, calibration standards and transformer manufacturing. Every day engineers are finding new and innovative uses for bond line spacers.
Barium Titanate Glass microspheres are high density solid glass spheres. At a Density of 4.5g/cc these solid glass spheres can be used for many scientific applications where high density and optical clarity is needed. In addition to high density they also offer an index of refraction of more than 1.9.
For those scientists who are looking to use silver coated materials such as silver coated microspheres in biomedical applications, it is important to understand whether they are bio-compatable. A selection of abstracts and article references related to the biocompatability of silver follow:
Barium Titanate Glass Microspheres are excellent for use as a functional retro reflective additive to paints and coatings. Spheres with sizes of about 50 micron (~0.002 inches) mean diameter provide a small enough size for most coatings while offering a large enough size to reflective a significant amount of light. Barium Titanate Glass Spheres are offered…
A process for forming hollow glass micro-spheres with walls of controllably variable thickness in a size range of 50 to 5,000 microns, embodying (1) preparation of a water slurry of finely particulated, high temperature and low temperature glass formers; (2) prilling the slurry in a vertical spray drying tower; (3) separating and supporting the individual prilled feed material; (4)…
Borosilicate glass offers advantages over standard soda lime glass microbeads.
The high roundness, and low thermal expansion make…
Cospheric announces new particle size ranges for its BKPMS, Paramagnetic Microsphere product.
Thanks to customer demand for narrower particle size ranges of paramagnetic microspheres. Cospheric has added the following sizes to its extensive inventory of microspheres offered in the dry powder form:
