Breaking Down the Features of Pall Supor PES Membrane Disc Filters 142mm Pack of 25

Specifications

The Pall Supor PES Membrane Disc Filters 142mm Pack of 25 come with a clear set of specifications that highlight their intended application and performance capabilities. The most crucial of these is the 0.8 micron pore size. This specific pore size is ideal for critical sterilizing-grade filtration, effectively removing bacteria and larger microorganisms while allowing for a significant fluid flow.

The 142 mm diameter provides a generous filtration surface area. This larger diameter is essential for processing larger volumes of fluid more efficiently, reducing the overall time required for filtration tasks. It also means fewer filters are needed for a given volume, contributing to cost-effectiveness over time.

The material itself, Supor hydrophilic polyethersulfone (PES) membrane, is a key differentiator. This material is known for its high flow rates, low protein binding, and excellent chemical compatibility. This makes it exceptionally well-suited for biological and pharmaceutical applications where sample integrity is paramount. The tabbed design is another important specification, offering a practical advantage for handling and secure installation within filtration systems.
