20090235722 | APPARATUS AND METHODS FOR LEAK DETECTION IN BIOPROCESSING BAGS - An apparatus detects a leak of an electrically conductive fluid from a disposable plastic bag used in mixing applications, such as during bioprocessing in a sterile environment. In one embodiment, the bag is associated with a sensor for detecting a leak from an interior compartment. The sensor may be arranged to detect either a leak internal to the at least two material layers of the bag or external to the outer layer, or both. Related methods are also disclosed. | 09-24-2009 |
20100157725 | Roller Bearing for a Fluid-Agitating Element and Associated Vessel - In a vessel, such as a flexible bag, a fluid is received and agitated using an internal fluid-agitating element driven by an external motive device and supported by a bearing, such as a roller bearing. The bearing may comprise a thrust bearing having at least one race fabricated of polyvinylidene fluoride and a plurality of associated rollers, preferably comprising a ceramic material, such as silicon nitride. Experiments show beneficial results in terms of particle generation when this particular combination of materials is used in the context of agitating fluids, and benefits as well when different materials are used to form the rollers. | 06-24-2010 |
20100197003 | BIOREACTOR - A mixing bag for use in bioprocessing in which a fluid is received and agitated using an internal fluid-agitating element driven by an external motive device is disclosed.

20110011164 | APPARATUS AND METHOD FOR THE INTEGRITY TESTING OF FLEXIBLE CONTAINERS - An apparatus for integrity testing a first container having a flexible body at least partially defining a first interior chamber using a second container having a second, preferably sterilized interior chamber at least partially filled with a detectable gas. A sensor associated with a detection chamber for receiving the flexible container, and possibly the second container as well, senses the presence of the detectable gas external to the first interior chamber in the event of a leak of the detectable gas therefrom. Related methods also involve integrity testing of fluid processing bags and other types of flexible containers. | 01-20-2011 |
20120118885 | Mixing Vessel Alignment Systems, Devices, and Related Methods - Various alignment systems, devices, and related methods are for use in associated with mixing of fluid in a vessel, such as a flexible bag, using an internal fluid-agitating element driven by an external motive device. | 05-17-2012 |
20120152769 | MIXING BAG WITH INTEGRAL SPARGER AND SENSOR RECEIVER - A mixing bag for use in bioprocessing in which a fluid is received and agitated using an internal fluid-agitating element driven by an external motive device is disclosed. The bag may include an integral sparger and sensor receiver. Related methods are also disclosed. | 06-21-2012 |
20120281494 | MIXING BAG OR VESSEL WITH A FLUID-AGITATING ELEMENT - A vessel receives and agitates a fluid using an internal fluid-agitating element driven by an external motive device. In one aspect, the vessel is a bag including a first receiver for receiving and holding a fluid-agitating element at a home location.
