The trusted name in laboratory supplies for 40 years.
Diamond® PureFlow™ bottle top filter units from Globe Scientific are essential components in large volume filtration, seamlessly fitting onto Diamond® PureFlow™ solution bottles or other laboratory media bottles with GL45 threads. These top filters are available in multiple configurations, ensuring compatibility and flexibility across a wide range of laboratory applications.
Featuring low protein binding Polyether Sulfone (PES) membranes, Diamond PureFlow™ bottle top filters are ideal for the clarification, separation, or sterilization of aqueous solutions, including cell culture media, biological samples, and laboratory reagents. The filters are available in various porosities—0.10μm, 0.22μm, and 0.45μm—to meet the diverse requirements of different applications. Each filter unit is clearly marked with its membrane type and porosity, aiding in straightforward identification and selection.
Engineered for maximum laboratory efficiency and safety, these filter units include a multi-step, angled hose barb that accommodates multiple sizes of vacuum lines, ensuring stability on the benchtop during use. The units are crafted from high-quality virgin USP Class VI polystyrene (PS) and acrylonitrile butadiene styrene (ABS), materials known for their durability and chemical resistance, which contribute to the overall reliability and performance of the filtration process.
