20140060215 | Automated Aseptic Sampling Workstations and Sample Collection Devices Therefore - A sample collection device is provided. The collection device includes an input conduit, a plurality of automated sample collection bags, a waste collection bag, and a valve block. The input conduit is connectable to a fluid processing line. The automated sample collection bags each have a sample volume and the waste collection bag has a waste volume. The valve block a plurality of three-way valves and an output, where the plurality of three-way valves correspond in number to the plurality of automated sample collection bags, each of the three-way valves placing the input conduit in fluid communication with a different one of the plurality of sample collection bags. The output is in fluid communication with the waste collection bag. The collection device has a ratio of the waste volume to the sample volume of not more than 15:1. | 03-06-2014 |
20140060214 | Automated Aseptic Sampling Workstations and Sample Collection Devices Therefore - A method of taking a fluid samples from a processing line is provided that includes: placing an input conduit in fluid communication with the processing line; operatively coupling the input conduit to a peristaltic pump and a valve block; operatively coupling the valve block to a valve actuator so that the valves are movable among an off position, a flush position, and a sample position; controlling the valve actuator to move the valves to the flush position and turning on the peristaltic pump so that fluid from the processing line is pumped to a waste bag; and controlling the valve actuator to move a particular valve to the sample position and to move any valve upstream of the particular valve to the flush position while the peristaltic pump remains on so that fluid from the processing line is pumped to the sample bag associated with the particular valve. | 03-06-2014 |
20140007711 | LIQUID COLLECTION METHODS AND APARATUSES FOR DETECTING VIRUS DEACTIVATION - A liquid collection device is provided. The device includes an input conduit, an output conduit, a plurality of product collection containers, and a valve block. The input and output conduits are connectable to a liquid processing line. The valve block has a valve block input in fluid communication with the input conduit, a valve block output in fluid communication with the output conduit, and a plurality of valves. The valves correspond in number to product collection containers and each valve places the input conduit in liquid communication with a different one of the product collection containers. An automated liquid collection workstation for use with the liquid collection device and a method of automatically collecting liquid from a processing line or vessel are also provided. | 01-09-2014 |
20120220441 | CONTINUOUS FLOW ULTRA-CENTRIFUGATION SYSTEMS - A continuous flow centrifuge system is provided. The system includes a rotor, a stator, a stator housing, upper and lower bearing plates, upper and lower bearings, first and second snap rings, and lip seal. The upper bearing rotatably secures a shaft of the rotor in the upper bearing plate. The first snap ring secures the upper bearing to the rotor shaft. The lip seal is over the upper bearing and forms a rotatable seal with the upper bearing plate. The second snap ring secures the lip seal to an inner diameter of the upper bearing plate. The upper and lower bearing plates are secured to the stator housing so that the rotor is operatively aligned with the stator. | 08-30-2012 |
20120138156 | AUTOMATED ASEPTIC LIQUID COLLECTION WORKSTATIONS AND COLLECTION DEVICES THEREFORE - An automated liquid collection workstation is provided. The workstation includes a processor, a peristaltic pump, a valve actuator, and an algorithm. The peristaltic pump and the valve actuator are in electrical communication with the processor. The valve actuator can move a plurality of valves, when disposed therein, among an off position, a flush position, and a collection position. The algorithm is resident on the processor and is configured to: move all of the valves to the off position and place the pump in an off state when no sampling or flushing is required, move all of the valves to the flush position and place the pump in an on state for a predetermined flush time period when flushing is required, and move a respective one of the valves to the collection position, move any of the valves upstream of the respective valve to the flush position, and place the pump to the on state for a predetermined collection time period when collection is required. | 06-07-2012 |
