Abstract: A testing apparatus employs an interface module removably attached to a filter testing device. The interface module includes a first flowpath communicating with an outlet of the testing device and a housing of the filter device, a first valve disposed in the first flowpath, a second flowpath communicating with the housing of the filter device and an exhaust, a second valve disposed in the second flowpath, and an enclosure enclosing the first flowpath, the first valve, the second flowpath, and the second valve. The interface module is cleanable and/or sterilizable, and replaceable. A filter integrity testing method uses an interface module to prevent contamination of the testing device and cross-contamination of different filter devices and avoid liquid ingress into the testing device.

Abstract: A method and apparatus for providing more reliable wireless communication and power to sensors in electrically challenging bioprocess environments is disclosed. An unconnected antenna is located within the bioprocess environment, preferably in the same plane as the primary powered antenna. This unconnected antenna, also referred to as reflective antenna, enhances and confines the electromagnetic field created by the powered antenna. This reflective antenna is incorporated in or proximate to the devices containing a sensor or communication device. In one embodiment, the reflective antenna is incorporated into the filter housing. In another embodiment, it is incorporated into the filtering element itself. In another embodiment, it is incorporated into or affixed on the disposable bioprocess components, such as bags and tubes.
