Select Microspheres by Density:

Specific density microspheres are often desired for flow visualization studies, as well as creating a stable solution of particles that do not settle to the bottom or float on top of the suspending fluid. Standard products are in-stock and ready to ship within 1-2 business days.

We also have capability to manufacture custom density microspheres for specific applications, contact for a custom quote and lead time.
