FAQ
Filtration membrane discs are used to remove particles, clarify liquids and support microbiology or analytical workflows. On this page, Merck, Cytiva, Sartorius, Fisherbrand and Thermo Scientific options cover common pore sizes and disc diameters for routine lab filtration.
Choose pore size based on the particles you need to retain. Larger pores suit faster clarification, while smaller pores support tighter retention and cleaner filtrates. Merck, Cytiva and Sartorius discs on this page include common laboratory sizes such as 0.45 µm, 0.22 µm and 0.2 µm.
The page is built around five top brands: Merck, Cytiva, Sartorius, Fisherbrand and Thermo Scientific. That mix gives buyers a clear route to compare membrane material, format and pore size without leaving the filtration membrane discs category.
47 mm discs are a practical standard for many bench-top filtration setups, including sample prep, routine clarification and membrane-based testing. Fisherbrand, Merck, Cytiva and Sartorius discs all have 47 mm options here, making side-by-side comparison simple.
Comparing these brands helps teams match performance, format and value more efficiently. Merck and Cytiva cover broad membrane choices, Sartorius brings strong disc formats, Fisherbrand products supports routine lab use, and Thermo Scientific products adds recognised filtration accessories and membranes.
