| 20100267539 | CENTRIFUGE WITH POLYMERIZING ENERGY SOURCE - Methods for using a centrifuge are presented. A vessel containing a sample and a separator substance is placed within a centrifuge. Upon sufficient centrifugation, the sample separates into two or more fractions separated by the separator substance. The centrifuge exposes the separator substance to a sufficient energy to polymerize the separator substance to produce a hardened barrier between the fractions. | 10-21-2010 |
| 20120071313 | CENTRIFUGE HAVING A LUBRICANT SYSTEM - Disclosed is a centrifuge including a rotatable centrifugal drum and a drive spindle to drive the centrifugal drum. The drive spindle is rotatably mounted via a bearing in a housing supported elastically on a machine framework. Further included is a drive device including a drive motor to rotate the drive spindle and a lubricant system to lubricate the bearing. The lubricant system is configured to deliver lubricant from a lubricant supply tank through a lubricant channel into a region of the bearing. An injection device is arranged downstream of the lubricant-supply tank and is configured to deliver the lubricant into the region of the bearing by dispensing quantities of lubricant in temporally discrete pulses with a limited-time air stream. A method is disclosed of directing lubricant into a region of a bearing of the centrifuge as noted above. | 03-22-2012 |
| 20120295781 | MICROFLUIDIC DEVICE FOR WHOLE BLOOD SAMPLE PREPARATION - A CD-based device for separating plasma from whole blood includes a substrate, a sedimentation chamber disposed in the substrate, and a collection chamber disposed in the substrate and in fluidic communication with the sedimentation chamber through a siphon channel. The sedimentation chamber includes a plurality of finger-like structures disposed along a radially outward edge of the sedimentation chamber, and protruding radially inward relative to the axis of rotation of the substrate. A method for separating plasma from whole blood using the CD-based device includes introducing a blood sample into the sedimentation chamber, rotating the substrate about an axis of rotation at a first rotational speed to separate the plasma from blood cells, and rotating the substrate about the axis of rotation at a second rotational speed, which is lower than the first rotational speed, to move the plasma from the sedimentation chamber into the collection chamber. | 11-22-2012 |
| 20130190159 | CENTRIFUGE - A centrifuge capable of suppressing a long-time depressurization as compared with the case of starting depressurizing after cooling has been completed as well as shortening a cooling time of a rotor and a sample in the rotor is achieved as compared with the case of starting cooling is at the same time with depressurization. Operation of a Peltier element is started at the same time with operation start of the centrifuge. A bowl is cooled by heat absorption of the Peltier element, and the rotor is cooled by the bowl with using ambient air as a thermal medium. At this time, a vacuum pump depressurizing a rotor chamber is in an OFF state (ambient conditions). After a predetermined time is elapsed, the vacuum pump is turned on to start depressurization of the inside of the rotor chamber. | 07-25-2013 |
| 20140329656 | System and Method For Automated Platelet Wash - A method for washing platelets includes introducing anticoagulant into a platelet product container, drawing re-anticoagulated platelet product from the platelet product container, and introducing it into a centrifuge bowl. The centrifuge bowl separates the platelets from the supernatant in which they are suspended. The method then washes the platelets by introducing wash solution into the centrifuge bowl. As the wash solution is introduced into the bowl, it displaces the supernatant from the bowl and into a waste container. The method then introduces platelet additive solution into the centrifuge bowl, which displaces the wash solution from the centrifuge bowl and into the waste container and further wash the platelets. The method then repeatedly accelerates and decelerates the centrifuge bowl to resuspend the platelets in the platelet additive solution. | 11-06-2014 |
| 20140364296 | CENTRIFUGE VESSELS SUITABLE FOR LIVE CELL PROCESSING AND ASSOCIATED SYSTEMS AND METHODS - Centrifuge vessels suitable for live cell processing include a bowl with a cap, and a tube inside the bowl extending between the cap and a lower portion of the bowl. The bottom of the bowl can have a closed annular ring surrounding a center mound. The vessels can be particularly suitable for processing low volumes of live cells for vaccines or other therapies. | 12-11-2014 |
