A method for leak testing includes a leak testing step and a reference leak step. In the leak testing step, a hollow work 20 as a test object is encapsulated in a work capsule 11. A test pressure is supplied to the work capsule 11 through a path 2a connected to the work capsule. A variation of pressure inside the work capsule 11 is detected in a condition in which the path 2a is shut-off, and a judgment is made whether a leakage through the work is generated based on the detected output. In the reference leak step, a reference leak device 30 having a known pinhole 31a is mounted on a work 20 for reference leakage that is same as the work 20 as the test object. The work 20 for reference leakage is encapsulated in the work capsule 11. The test pressure is supplied to the work capsule 11 via the path 2a, and a reference leakage is generated in the work 20 for reference leakage via the reference leak device 30 in a condition in which the path 2a is shut-off. A variation of pressure inside the work capsule 11 accompanying the reference leakage is detected.

Devices and methods for container closure integrity testing by leak testing, in particular of pharmaceutical containers, which are composed of two parts, the container itself, which shows an opening, and a closure system that is used to close this opening of the container, such as a lid; and their application in quality control.

The present invention relates to a method for producing a bag in the interior space of a container and for testing said bag, and to a system for this purpose, to a computer program product for execution, and to the use of the system for the methods.

Method for testing a test piece for the presence of a leak using a foil chamber, wherein the foil chamber has walls having at least one flexible wall region to which a measurement volume adjoins and is arranged on that side of the flexible wall region opposite the foil chamber volume and is hermetically separated from the foil chamber volume, having the following steps: placing the test piece in the foil chamber, closing the foil chamber, evacuating the foil chamber and monitoring the measurement volume during evacuation of the foil chamber, using the result of the monitoring to reach a conclusion regarding the magnitude of a leak, characterized in that a venting valve connecting the measurement volume to the atmosphere is closed when the pressure in the measurement volume is below a predefined threshold value, and is opened as soon as the pressure exceeds the threshold value.

The present invention relates to a flow wrapper which comprises a form and/or film tube, which forms the planar film into a film tube and/or fills the film tube with a packaging item and which comprises means to provide a longitudinal- and/or cross-seal to the film tube.

A leak detection and recovery system for use with DRA equipment. The system is intended to reduce the risk of a chemical release into the environment, namely the soil, ground water, and waterways. The system may provide clean collection of leaked DRA, early detection of DRA leaks, immediate notification of DRA leaks, and re-use of leaked DRA through clean recovery with no hazardous waste disposal.

Device for testing the sealing of at least one system for insulating two mediums in a sealed manner, the system including a flange and a sealed door mounted in the flange, the test device including a casing including an inflatable seal intended to contact, in the inflated state, with the system and to ensure a sealing enabling the definition of a test volume between the system and the casing, a pneumatic pump and a pneumatic circuit configured to connect, in a first step, the pump to the inflatable seal such that the pump inflates the inflatable seal, and in a second step the pump to the test volume such that the pump generates in the test volume a pressure at a given value, and sensor for measuring the pressure in the test volume.

This disclosure relates to equipment utilized to manufacture chemical agents, particularly biopharmaceuticals, using Disposable Containers (DCs).

The invention discloses devices and methods for container closure integrity testing by leak testing, in particular of pharmaceutical containers, which are composed of two parts, the container itself, which shows an opening, and a closure system that is used to close this opening of the container, such as a lid; and their application in quality control.

Embodiments of the present invention provide a system and method to perform drying and testing of organometallic and organosilane precursor source ampoules that have been cleaned for re-use. The drying and quality control testing is performed in a single location with a single apparatus requiring only one manual connection/disconnection step of the ampoule to the apparatus. The testing includes analyses for residual moisture, entrained particulate matter, differential pressure, and helium leak checking.
