- China Porous Filters: Over 18 years of filtration R&D, serving both Fortune 500 and local enterprises, with major international collaborations (Siemens, Medline, BASF). Extensive portfolio backed by ISO 9001, ISO 13485, and customized engineering solutions.
- Sartorius, Pall, Millipore: Globally recognized, strong R&D, but more standardized (non-customizable) product lines for syringe and medical filters. More restricted in geometry/porosity tailor-making.
- Porosity & Pore Size: 0.1–100 μm tailored to specific particle/bioburden retention requirements (e.g. high-retention 0.22 μm for sterile filtration, 10-50 μm for particulate control in process gases).
- Shape/Fitting: Discs, rods, tubes, plug inserts, cartridge blocks—adaptable to any housing (DIN/ANSI/ISO dimensions supported).
- Composite Structures: Integration of UHMW-PE membranes with PTFE/PVDF/Nylon fleece for layered or zonal filtration.
- Color/Visual ID: Custom color ID rings, etching, or laser marking to match traceability programs.
- OEM Contract Manufacturing: Sterile barrier packaging, private labelling, supply-chain support.
- Laboratory Sample Preparation: UHMW-PE syringe filters achieve >99.98% retention rates of 0.22 μm particles, verified via ISO 2942 bubble test methodologies; compatible with hazardous chemicals (strong acids/bases, organic solvents) for HPLC and GC-MS applications.
- Medical Devices: Utilized as venting filters in IV sets, catheters, and blood transfusion kits thanks to their non-cytotoxic, anti-fouling surfaces and FDA/ISO 13485 compliance.
- Industrial Gas Filtration: Sintered UHMW-PE filters installed for compressor venting, chemical degassing, and corrosion-prone environments exhibit >5-year service life even at 24/7 operation.
