When stored in a cool, dry environment, Cospheric spherical particles have an indefinite shelf life. Containers should be kept closed to minimize contamination. Refrigeration is recommended for Density Marker Beads.
None of our products are toxic or require special
shipping. When working with particles less than 10 micron in diameter we recommed wearing a dust mask and working inside an exhaust hood to minimize the posibility of inhaling the particles. All standard precaustions of working with small particles are to be followed. All spherical particles are slippery when spilled, due to ball-bearing effect. Good housekeeping is required. We encourage customers to perform their own testing and assessment for suitability of use for their specific application.
of calculated number of spheres per gram of material based on various
microsphere diameters for glass and polymer microspheres can be found in

Spheres per Gram.
This depends on the surface properties of the material the microspheres are made from (hydrophobic or hydrophillic).
Suspension of hydrophobic microspheres in water (aqueous) solution, specifically for flow visualization, Particle Image Velocimetry (PIV) or biological applications require the use of a surfactant.
We recommend to use concentrated Simple Green All Purpose Cleaner (www.simplegreen.com) Cover dry spheres with concentrated simple green
and let sit for approximately 5 min before dispersing in water.
