Material Safety Data Sheet - Polyethylene Spheres, Beads, Microspheres, and Nanospheres

Barium Sulfate Polymer Microspheres are created for scientists searching for X-ray opaque microspheres with high sphericity and tight particle size distribution. Barium Sulfate is embedded within the microspheres and acts as a radio contrast agent for X-ray imaging and other diagnostic procedures. These spheres are also know as barium impregnated polyethylene spheres (BIPS) and are often used in veterinary medicine. We recommend the higher density 1.5g/cc product for optimal contrast.


White barium sulfate polyethylene microspheres are supplied in dry powder form and specifically designed with density 1.00 g/cc, for suspension in fresh water, enabling flow visualization and PIV analysis of fluid flow in a device. Controlled particle size ranges enable investigation of maximum particle size passing through the openings, filters and membranes. Polyethylene microspheres are hydrophobic and need to be coated with a surfactant prior to suspension in water. We recommend Tween 80 Bio-compatible Surfactant.


Density: 0.99g/cc-1.01g/cc (perfect for suspension in water)
Particles in Size Range: > 90%
Spherical Particles: >90%
