  • Patent number: 10052427
    Abstract: A filter apparatus, a method for the manufacture of the filter apparatus, the use of the filter apparatus in medical, chemical and/or biotechnological applications, and an apparatus for use in the manufacture of the filter apparatus. The filter apparatus has a cylindrical housing and a plurality of hollow fibers. The hollow fibers are combined to form a bundle in the housing and are embedded and held in each case at the end sides in a molding compound. The filtrate space is filled with particles of a chemically or physically active substance.

  • Publication number: 20120208256
    Abstract: An immobilized enzyme comprises a solid support, an enzyme linked to the solid support and a spacer for coupling the enzyme to the solid support. A method for the production of immobilized enzymes comprises: providing a solid support having amino-functional groups coupled to the support surface; covalently coupling the amino-functional groups with a thermally labile radical initiator; and, contacting the support surface with a solution of polymerizable monomers. The polymerizable monomers comprise functional groups which do not take part in radical polymerization, under conditions where thermally initiated graft copolymerization of the monomers takes place, to form polymer chains on the surface of the support. If the polymer chains do not already comprise primary amino-functional groups, the method further comprises transforming the functional groups in the polymer chains into groups comprising primary amino-functional groups.
