A method for conducting an integrity test on a flexible test container (1) includes arranging the test container (1) in an examination container (5) that is sealable in a fluid-tight manner, providing negative pressure in the interior of the sealed examination container (5), filling examination fluid into the test container (1) arranged in the examination container (5), detecting examination fluid present in the interior of the examination container (5), and providing negative pressure in the test container (1) arranged in the examination container (5) prior to filling the examination fluid. Prior to filling the examination fluid, the negative pressure in the test container (1) is lower than the negative pressure in the interior of the examination container (5), and the pressure difference between the negative pressure in the test container (1) and the negative pressure in the interior of the sealed examination container (5) is more than 0 mbar and a maximum of 100 mbar.

A glove inspection device (20) is provided for testing the integrity of a protective glove (10). The device (20) includes a base (22) having a glove mount feature (24) configured to sealingly receive a cuff (18) of a protective glove (10). A pressure sensor (26) is operably connected to the base (22) and is configured to monitor an internal pressure of a protective glove (10) mounted on the glove mount feature (24). A user interface (28) is operably connected to the pressure sensor (26) to provide a representation of the internal pressure monitored by the pressure sensor (26).

A test system and a corresponding method for testing the seal of a glove which is installed in a port of an isolator, including a test disc which can be connected in a hermetically sealed fashion to the port. The glove and test disc define a sealed glove volume which can be placed under excess pressure. The test disc has a pressure-measuring device with a microprocessor and a memory for recording and storing a pressure profile in the glove volume and a data interface. The glove and port have identification elements which are read by a reading device of the test disc and information concerning the pressure profile along with the identities of the glove and port are transmitted wirelessly to an evaluation unit which estimates and records a residual period of use of the glove. A plurality of gloves in ports can be tested simultaneously.

Testing of vacuum bags used in manufacturing of complex co-cure composite structures provides leak detection that allows an operator to identify leaks within a custom vacuum bag without further damaging the bag, such as by cutting vacuum ports into the bag. Such leak detection can allow the operator to find and repair the leak or, if not repairable or at a location of the bag for which repair is not feasible, take other corrective action.

Disclosed is a bag including: a first envelope having at least one fill and/or discharge orifice for a biopharmaceutical fluid and a fill and/or discharge tube associated in a fluidtight manner with the fill and/or discharge orifice, a second envelope within which the first envelope is located, and a spacer element. The first envelope, the second envelope, and the spacer element form a coherent whole, in particular during use of the bag, and the fill and/or discharge tube traverses the second envelope by a fluidtight connection, the fill and/or discharge inlet being located outside the second envelope.

Device for detecting breakages in high-pressure processing bags, wherein an elongated electrode (1) partially extends through the inside of one of the plugs (5a, 5b) of the device in its proximal part and, in its distal part, extends into the bag (6) of the product to be processed, the electrode being electrically insulated by an insulator (2) along its entire length, except in the part that is located inside the bag (6) and which is in contact with the product, wherein the proximal part of the electrode (1), which extends out of the plug, is connected to a power source and a device for measuring the electrical current, the resistance or the capacitance of a circuit, wherein said device is electrically connected by closing the circuit between the electrode and the pressurization water if the bag breaks.

A method for improving reliability of an integrity or leak test includes determining at least one first parameter indicative of: a first volume of a sample, a first temperature of the sample, a first pressure of the sample and/or a first assessment of integrity of the sample. The method further determines at least one second parameter indicative of a deviation from the first parameter and at least one third parameter indicative of a second assessment of the integrity of the sample. The second assessment provides an indication of a passed or failed test. The method further determines whether the deviation has an impact on the indication of the second assessment. When the deviation is determined to have an impact on the indication of the second assessment, the method comprises identifying a possibility that the indication of the second assessment is incorrect.

A method for conducting an integrity test on a flexible test container (1) includes arranging the test container (1) in an examination container (5) that is sealable in a fluid-tight manner, providing negative pressure in the interior of the sealed examination container (5), filling examination fluid into the test container (1) arranged in the examination container (5), detecting examination fluid present in the interior of the examination container (5), and providing negative pressure in the test container (1) arranged in the examination container (5) prior to filling examination fluid being. The negative pressure in the test container (1) is lower than the negative pressure in the interior of the examination container (5), and the pressure difference between the negative pressure in the test container (1) and the negative pressure in the interior of the sealed examination container (5) is more than 0 mbar and a maximum of 100 mbar.

An adaptor for use to direct pressurized fluid into a glove to inflate the glove is disclosed. A kit for holding several test components for use to inflate a glove is also disclosed. The kit is provided for testing a glove for leakage. The components include an adaptor, a strap, and a portable pump, which can be either a DC-powered air compressor or a hand or foot pump.
