This product is a hydrophilic PVDF microporous filter membrane developed by Shanghai Xingya, designed for precise filtration in aqueous and biological applications. With a uniform microporous structure available in pore sizes ranging from 0.15 µm to 0.8 µm and a 50 mm diameter, it offers reliable separation performance for particle retention and sample clarification. The hydrophilic nature of the membrane ensures efficient flow of water-based solutions without the need for pre-wetting. It is commonly used in laboratory filtration, microbial analysis, and quality control processes where consistent pore size and chemical resistance are required. The polyvinylidene fluoride material provides good thermal stability and low protein binding, making it suitable for sensitive biological and pharmaceutical samples. This membrane is a practical choice for research environments requiring reproducible filtration results.
