Application Fields
Gas / Venting Filtration
Membrane Solutions provides gas filtration for semiconductors, pharma, and food processing, ensuring purity with stable chemical properties. Our hydrophobic venting membrane is designed for automotive (headlamps, valves), consumer electronics (microphones, phones, earphones), and sensors (pressure sensors). Key advantages: high air permeability, high water pressure resistance, easy post-processing, and PFAS Free. Whether for precision gas filtration or protective venting, our solutions enhance efficiency, reliability, and sustainability.
Liquid Filtration
Membrane Solutions provides high‑flux, high‑precision liquid filtration for chemical, pharma, water treatment, and food & beverage. Our membranes remove particles, bacteria, viruses, and chemical pollutants, with durability under complex conditions. Applications: food/chemical (solvent/chemical filtration), semiconductor (strong acid/strong oxidizer filtration), biomedical (sterilization, ozone water, H₂O₂ filtration). Advantages: high efficiency, high flux, high dirt holding capacity, high cleanliness, biocompatibility.
Protein Transfer
Western blot uses SDS-PAGE to separate proteins, then transfers them onto PVDF or NC membranes while preserving biological activity. Antibody binding yields clear bands, with thickness reflecting protein mass, enabling detection down to 1ng. Membrane Solutions provides high-performance transfer membranes for crisp, reliable protein bands. Additionally, our positive-charged nylon membranes offer strong endotoxin removal for biomedical applications. Key advantages: clear protein transfer bands and superior endotoxin removal capacity. Widely used in molecular biology, biochemistry, and immunogenetics.
Successful Applications
Biopharma & Life Sciences
Hydrophilic PTFE membranes are made into sterilizing-grade filter cartridges that withstand multiple autoclave cycles, used in aseptic filling to reduce contamination risks. Hydrophobic PTFE membranes are used in freeze‑drying containers and shake flasks, demonstrating high tolerance and high air permeability. Highly asymmetric PES membranes are made into sterilizing-grade filter cartridges achieving LRV >7 and low endotoxin, ensuring bioproduct safety. Ultra‑low protein‑binding PVDF membranes are made into bioburden reduction sterilizing-grade filter cartridges with protein adsorption <4 mg /cm², improving antibody yields. Hydrophobic PES membranes are made into vent filters and aseptic connectors, meeting irradiation resistance and PFAS‑free requirements, widely adopted in single‑use bioprocessing systems.
Food & Beverage
Oleophobic PTFE (PFAS‑free) membranes are used as venting in freshness containers, offering high air permeability and oil repellency to prevent clogging and extend shelf life. Highly asymmetric PES membranes are made into pleated filter cartridges for tea beverage filtration, providing high flow rate and high dirt‑holding capacity, enabling cold clarification while preserving flavor. Hydrophilic PTFE membranes are made into sterilizing-grade filter cartridges for beverage process water and aseptic filling, ensuring microbial safety. These solutions improve clarity, extend shelf life, and reduce energy consumption.
Electronics & Chemicals
Hydrophobic PTFE membranes are made into high‑precision filter cartridges for particle control in developers and etchants. Non‑dewetting PTFE membranes have elevated surface energy, remain hydrophilic in aqueous solutions after alcohol permeation, eliminating repeated pre‑wetting, and are widely used in semiconductor strong acid and strong oxidizer filtration. Nylon+ membranes are made into pre‑filtration filter cartridges, utilizing stable positive charge for chemical APIs and photoresist pre‑filtration, extending final filter cartridge life. These solutions meet the requirements of high‑purity filtration and demanding process stability.
Industrial & Environmental
Hydrophilic PTFE membranes are made into particle removal filter cartridges, achieving high‑precision particle control in industrial fluids with high flow rate and high bubble point, reducing equipment wear. Hydrophilic PVDF membranes are made into pleated filter cartridges for high‑temperature liquid filtration, resisting 120°C and performing stably in industrial hot water recirculation. Hydrophobic PTFE membranes are made into venting for tank protection, preventing contamination and moisture ingress. These products ensure filtration precision, high‑temperature resistance, and moisture protection for chemical, pharmaceutical, and electronics industries.
