Whatman 6717-9501 Polycap TC 150, 0.2/0.1 micrometer Pore Size, Polyethersulfone, 1/2 SB Inlet, 1/2 SB Outlet, Sterile, 1/pk

This is a sterile capsule filter designed for critical aqueous filtration, suitable for removing fine particles, bacteria, and fungi from liquids in life science, pharmaceutical, and research applications.

The dual pore size (0.2 μm and 0.1 μm) refers to two layers of the membrane that help provide high filtration efficiency — the 0.2 μm layer removes particulate matter and bacteria, while the 0.1 μm layer offers finer filtration for more demanding applications.

The filter uses a polyethersulfone (PES) membrane, which is hydrophilic, high flow-rate, and low in protein binding. This makes it ideal for filtering aqueous biological solutions with minimal loss of proteins or activity of target molecules.

With its sterile PES membrane and integrity testing during manufacturing, this filter is suitable for sterile filtration of tissue culture media, pharmaceutical buffers, and other critical lab solutions, helping ensure removal of microbial contaminants.

The “1/2 SB inlet and outlet” refers to the stepped barb connectors that allow you to easily attach standard laboratory tubing (typically 1/4″–3/8″ or 3/8″–1/2″ sizes), enabling quick setup in gravity or pressure-driven filtration systems.
