Shanghai Xingya Water System PES Disposable Needle Filter

This product is designed for efficient aqueous sample filtration in laboratory environments. Manufactured by Shanghai Xingya, these disposable needle filters incorporate a hydrophilic polyethersulfone (PES) membrane, which provides low protein binding and high flow rates. Available in 13 mm and 25 mm diameters with pore sizes of 0.22 µm, 0.45 µm, and 0.8 µm, they can be selected for sterilization, clarification, or particle removal. The PES material ensures broad chemical compatibility with aqueous solutions, making the filters suitable for HPLC sample preparation, microbiological analysis, and routine filtration tasks. Each filter is individually packaged to maintain cleanliness and ease of use, supporting consistent and reproducible results in research and quality control workflows.
