Microspheres & injectables: controlling flow, packing, and surface area

Microspheres are chosen for their handling advantages—but the same product can behave very differently if you don’t define size distribution, density, and surface area.

Recommended products

• HA Microspheres for structured packing and surface
• 45S5 Microspheres for flow & packing studies
• PLLA Microspheres for polymer microsphere programs

Spec checklist

• Size window (D10/D50/D90) and method
• Bulk density / tap density target (if relevant)
• Surface area range
• Moisture control and packaging
