VARIOUS APPLICATION -PES sterilized needle syringe filters made of polyethersulfone microfiber hot melt bonded to a membrane material, which are widely used in various fields of life sciences to decontaminate all kinds of small-volume biological liquids, such as proteins, culture media, additives, buffers, reagents or drugs
UNIFORM PORE SIZE - Sterile PES Syringe Filter with uniform pore size structure makes sure of granule cell collection. PES Syringe Filter Diameter: 33mm and 0.22um pore size which can fastly sterilize of buffers, culture media or other solutions.
PES MATERIAL - The PES material has good hydrophilicity and can be wetted quickly and completely, and the asymmetric microporous structure of the PES material gives it a high water flux. It has good dirt-holding capacity. It also has low protein adsorption and low dissolution properties: it is not easy to interact with blood and other biological products. In addition, PES materials have heat resistance and acid and alkali resistance.
PRODUCT DESIGN FEATURES - SemmerFeld needle syringe filters feature a unique state-of-the-art design with a female luer lock inlet and male luer slip outlet. The shell is made of polypropylene (PP), and the interior uses a special three-layer design "upper layer - GF pre-filter, middle layer - PES filter membrane, and lower layer - PP diversion trench". This makes the needle syringe filters have a great capacity to absorb dirt.
INSPECTION & VERIFICATION - Chudeng needle syringe filters are pre-factory tested for pore size, flux, precipitation, and gamma radiation sterilization. It is ISO90001 certified.
