Hollow and solid glass microspheres with perfect sphericity, tight tolerances and particle size distributions for biomedical, life sciences, microscopy, automotive, high-tech equipment and specialty applications.
High quality solid polyethylene microspheres available not only in a wide variety of colors, but also with opaque, paramagnetic, fluorescent, and phosphorescent properties. Some polyethylene microspheres have a strong triboelectric (electrostatic) charge.
Monodisperse and polydisperse grades of silica nanospheres and microspheres are offered as free-flowing white powder and have an exceptional degree of roundness: >99%.
Poly(methyl methacrylate) or PMMA microspheres are often used as spacers, medical fillers, and cores for metal coated spheres in a wide variety of applications including porous ceramics, self assembled microfluidic devices, biomedical research and life sciences.
A wide selection of size ranges of high quality corrosion resistant stainless steel and titanium microspheres from 1um on up to 1.2mm.
Polypropylene Spheres are highly spherical plastic particles. Large, highly-spherical particles of density less than 1g/cc are a useful tool as reference particles in simulation experiments and process troubleshooting.
Polystyrene Spheres are highly spherical plastic particles in sizes between 2mm and 4.5mm. Large, highly-spherical particles of density greater than 1g/cc are a useful tool as reference particles in simulation experiments and process troubleshooting.
Large Cellulose Acetate Spheres are highly spherical plastic particles that are offered in a selection of bright colors and sizes between 1mm and 3mm. Cellulose Acetate Spheres have high impact and mechanical strength as well as high dielectric constant and good resistance to a variety of chemicals.
Most polymer microspheres are hydrophobic and require small quantities of surfactant in order to be suspended in an aqueous solution.
