20090238725 | FILTER VIAL - A filter vial and piston are provided where the vial has a cylindrical wall with a closed bottom and open top and with the hollow, tubular piston therein. The piston has a distal end covered by a cup having a proximal cup seal extending outward to engage the walls of the vial to form a fluid tight seal with the vial during use. The distal end of the piston has a piston flange extending outwardly and located adjacent a recess in the piston so the cup forms a snap fit over the piston flange and extends into the recess. The piston flange causes the cup to bulge sufficiently outward to form a fluid tight seal with the vial during use. A filter is placed in the bottom of the cup and abuts an inwardly extending lip on the cup. The filter is held against the lip by a piston support at the distal end of the piston. A cup support at a distal end of the cup also helps support the filter. | 09-24-2009 |

20100074803 | BUFFY COAT SEPARATOR FLOAT SYSTEM AND METHOD - A tube and float system for use in separation and axial expansion of the buffy coat includes a transparent or semi-transparent, flexible sample tube and a rigid separator float having a specific gravity intermediate that of red blood cells and plasma. The float includes a main body portion of reduced diameter to provide a clearance gap between the inner wall of the sample tube and the float. One or more protrusions on the main body portion serve to support the flexible tube. During centrifugation, the centrifugal force causes the diameter of the flexible tube to expand and permit density-based axial movement of the float in the tube. The float further includes a pressure relief system to alleviate pressure build up in the trapped red blood cell blood fraction below the float, thereby preventing red blood cells from being forced into the annular gap containing the buffy coat layers. | 03-25-2010 |

The use of inserts allows one to take a standard one-piece plate design with a heat sealed membrane and arrange for a universal plate format. The insert may act as a base for an extension plate that can be adhered, heat sealed or overmolded over the plate top and insert top to form a deep well plate. The plate conforms to the Society of Biological Standards Microplate Standards. Additionally, the inserts may be configured to give one a different well diameter (smaller, tapered, etc), to include various media such as chromatography resins, to include multiple layers of membrane and the like. A variety of inserts may be used in the same plate to create a minilab on a plate that is capable of conducting several steps of a process on the same (e.g (e.g. filter, wash, bind, elute, label, etc). | 09-16-2010 |
