Answer:It has a finer 0.2 µm nominal pore size while retaining the 47 mm disc format.
Answer:No. The 0.2 µm discs have a plain surface and no tab.
Answer:One package contains 100 membrane discs.
Pall Supor PES membrane discs combine a hydrophilic polyethersulfone membrane with a 0.2 µm nominal pore size for laboratory fine-filtration work. The 47 mm diameter fits compatible membrane holders, while the plain, ungridded surface and tab-free design suit standard disc filtration setups. A package contains 100 discs, making the format practical for repeated laboratory sample processing and filtration tests. Compared with coarser Supor PES discs, this 0.2 µm version addresses applications requiring finer nominal particle retention. Membrane disc selection must also consider chemical compatibility, sample composition, and the intended filtration method. A nominal pore-size description alone does not establish that an assembled process provides validated sterile filtration.
