| MAXX-Cap / Brevi-Cap capsule sizes | 2" up to 40", 0.2/0.1 µm, ultrapure polypropylene construction | Allied Fluid Products — Bay Area Fluid Handling & Sealing Distributor |
| Compliance stack | ISO 9001:2015, cGMP manufacturing in ISO Class 7 clean rooms, LAL endotoxin testing, bacterial challenge validated to ASTM F838, FDA-listed materials, steam and gamma sterilization validation | Allied Fluid Products — Bay Area Fluid Handling & Sealing Distributor |
Sterilizing-grade filtration for beverage or biopharma service is a compliance stack, not just a micron rating — a 0.2µm membrane alone doesn't establish sterility assurance without bacterial challenge validation to ASTM F838 against Brevundimonas diminuta and 100% integrity testing on every cartridge, which is the actual basis for a defensible sterile claim to a regulator or customer.
