Pall Rigimesh sintered metal mesh filter cartridges are constructed from fine-woven stainless steel wire mesh which is sintered at each wire contact point in a Pall-patented process to produce an extremely strong surface-sieving porous material with extremely narrow pore size distribution. Unlike unsintered meshes, Rigimesh media will not shift under stress. Sintering also enables the use of finer wires to produce more pores per unit area for higher flow rates and higher contaminant loading capacity. Rigimesh media is pleated to form double open-ended (DOE) MBS1000 style filter cartridges with applications in bulk active pharmaceutical chemical purification processes such as catalyst solids recovery and decolorizing carbon removal.
Single open-ended (SOE) AB sanitary and threaded styles are also available.
