  • Patent number: 11541355
    Abstract: The invention relates to a method of determining a permeation property of hollow-fibre membranes wherein the permeation property of the hollow-fibre membrane is determined on a hollow-fibre membrane bundle which has been introduced into a housing and has terminally open hollow-fibre membranes at a first end of the hollow-fibre membrane bundle and terminally closed hollow-fibre membranes at a second end of the hollow-fibre membrane bundle. The invention more particularly relates to a method of determining the ultrafiltration rate and/or the ultrafiltration coefficient of hollow-fibre membranes.
