Poture supported a Hangzhou-based biopharmaceutical company in upgrading its downstream purification process by designing and supplying 36 units of Class A cleanroom-certified ceramic membrane housings. Each unit underwent full ASME BPE 2022-compliant surface finish validation (Ra ≤ 0.4 μm), helium leak testing (<1×10⁻⁹ mbar·L/s), and pre-sterilization validation documentation. The housings were integrated into a fully automated tangential flow filtration (TFF) skid operating at 60°C with 0.1 µm ceramic membranes. Production commenced in August 2025; client reported 100% operational uptime over the first 90 days.
