Low protein binding Polyether Sulfone (PES) membranes make Diamond PureFlow™ vacuum filters perfect for clarification, separation, or sterilization of aqueous solutions including cell culture media, biological samples, and laboratory reagents. Filter membranes are available in 0.10, 0.22 and 0.45 µl porosities to meet the requirements of most applications. Membrane and porosity are clearly marked on each filter unit.

Engineered with laboratory efficiency and safety in mind, Diamond® PureFlow™ vacuum filter systems include a multi-step, angled hose barb that accepts multiple sizes of vacuum lines while keeping the system stable on the benchtop. Graduation markings are included on both the filter unit and solution bottle for easy reference during and after filtration operations. Diamond® PureFlow™ vacuum filter systems are molded from virgin USP Class VI polystyrene (PS) and acrylonitrile butadiene styrene (ABS).
