Lab macro-filtration screens - nets - meshes
Macro-filtration refers to the separation of suspended matter visible to the naked eye through a size selective barrier with a pore size greater than or equal to 5 µm. There are many types of screens/filters to meet various macro filtration applications. Among them, polymer woven mesh or stainless steel mesh is one of the most popular filters.
Mesh Screens for Macrofiltration Separations
We offer a wide range of woven filters, which are composed of single fibers woven into a mesh screen, and are characterized by precise mesh openings, percentage of open area and mesh thickness.
