Abstract:
1. A single-use bioreaction vessel comprising: a plastic wall containing an aperture therethrough; a membrane holder having a cylindrical portion and a flange portion affixed to the plastic wall, wherein the membrane holder is configured to removably mount an oxygen sensor external to the bioreaction vessel; and a window membrane composed of a plastic having a high oxygen permeability and being coupled to the membrane holder to seal the aperture, the window membrane being disposed to contact a bioreaction material within the single-use bioreaction vessel and wherein the window membrane is configured to contact the oxygen sensor when the oxygen sensor is mounted in the membrane holder; wherein the window membrane is located and sealed to the aperture of the bioreaction vessel; wherein the sensor body is configured to be removably coupleable such that the removal of the sensor body from the cylindrical portion does not breach the reaction vessel and the window membrane remains attached to the bioreaction vessel even after removal of the sensor body.
