摘要： Systems and methods for the manufacture of reinforced, three-zone, microporous phase inversion membrane having any one of a plurality of different possible pore sizes in any of the three zones from at least a single mother dope batch is disclosed. The systems and methods include formulating at least a single mother batch of dope in a vessel preferably maximizing the non-solvent to solvent ratio for a given weight percentage of polymer for use in a microporous phase inversion membrane production operation to produce three-zone phase inversion membranes having one of a plurality of different predetermined pore sizes in any or all of the three zones. The at least one mother dope batch is controllably formulated in at least one vessel such that the temperature of the dope does not exceed a predetermined maximum mixing temperature and is maintained at a relatively low temperature (lower than the mixing temperature) suitable for storage.

摘要： A process for producing an integral single layer polymeric microporous filter membrane within which a reinforcing web is embedded. The process comprises passing a reinforcing web through a first reservoir of casting solution of polymer and then simultaneously calendering both sides of the coated web to provide for penetration of the solution into the web and to remove substantially all entrapped air from the web. The calendered reinforcing web is then passed through a second reservoir of casting solution and then through a quenching bath to form micropores throughout the coatings.

摘要： A filter element comprising a hydrophilic organic polymeric microporous filter membrane having a preformed substantially non-porous sealing area and a filter housing having, preferably, a hydrophobic thermoplastic sealing surface in thermoplastic sealing relationship with the sealing area. Preferably, the filter membrane is a pleated cylindrical membrane and the housing includes endcaps thereto. The preferred membrane is nylon. The preferred pleated cylindrical membrane is produced from an elongated porous filtration area longitudinally bordered by substantially non-porous sealing areas. Such a membrane may be produced by a specific casting method or collapsing the pores along the longitudinal borders of the filtration area. The filter element is particularly useful for the filtration of aqueous liquids, particularly parenteral or body liquids.
