Hollow and Solid Glass Spheres - R&D Vials

R&D vials of hollow glass microspheres contain 10ml of spheres with density of 0.14g/cc in dry powder form. R&D vials of solid glass microspheres contain 25g of spheres with density of 2.52g/cc in dry powder form.

R&D vials are used for R&D applications, such as life sciences, biotechnology or process research. They are also often used as a test quantity for a large volume orders.

Large volume pricing and leadtimes are available by request.  Choose solid or hollow glass spheres.
