Answer:The printed grid supports visual examination and organized assessment of material retained on the membrane.
Answer:The membrane discs are 47 mm in diameter with a 0.45 µm nominal pore size.
Answer:No. These are gridded, tab-free membrane discs packed 100 per unit.
Pall Supor PES membrane discs provide 0.45 µm nominal filtration in a 47 mm format with a printed grid on the membrane surface. The grid assists visual examination and organized assessment of retained material where an application calls for a gridded membrane. These polyethersulfone discs are supplied without handling tabs, and the package contains 100 pieces. The membrane can be installed in a compatible 47 mm filtration holder for laboratory sample preparation or membrane-based testing. Gridded and plain 0.45 µm Supor discs are different ordering choices; the visible grid is a functional distinction independent of pore size. Match filtration conditions, grid suitability, and sample chemistry to the validated method.
