The 50 mL Bottle Top Vacuum Filter with a 0.22 μm polyvinylidene fluoride (PVDF) membrane is designed for high-performance sterile filtration of biological and chemical solutions. Known for its broad chemical compatibility and low extractables, PVDF is ideal for applications requiring low protein binding and high filtration precision.
With precise graduation marks and a robust outer structure, this compact unit is easy to handle and well-suited for small-volume filtration tasks. The universal hose connector allows quick integration with various vacuum systems, streamlining your lab’s workflow.
Each filter is gamma-ray sterilized, individually packaged, and certified to be endotoxin- and pyrogen-free to support contamination-free operation in research and clinical environments.
