Microspheres in R&D quantities

Order R&D vials of solid polyethylene, polymer, hollow glass, or metal coated microspheres.
Microspheres listed in R&D quantities of 10grams or less usually ship in 1-3 business days.

Note:
Small particle sizes (below 53 micron) come in 0.5g, 1g or 5g vials. 
Larger particle sizes (upto 1.2mm) come in 10g vials.
Hollow Glass microspheres are sold by volume: 10ml per vial.
