Solid Dosage Forms

Solid product may be produced by crystallization, where filters are used during production of the Active Pharmaceutical Ingredient, or by heat drying, granulation or other techniques. Granulators and mixers used for compounding powders have vent filters, especially where a vacuum is used. Stainless steel filters such as Pall's sintered metal mesh filter cartridges may be used, with sterile vent and gas filters used for more rigorous requirements. For highly-active ingredients, these filters are often used in GBK Containment Systems for operator safety.

Air used in conveying, de-dusting and other applications in handling pharmaceutical solids is also commonly sterilized by filtration.
