Patent number: 7993607Abstract: The invention concerns plasma separation on a microliter scale. The method/system according to the invention is able to provide plasma in the range of several microliters within a very short time as it is required, for example, in modern analyses by carrier-bound test elements. Plasma separation and plasma release is carried out in two separate consecutive steps of the method using the device according to the invention such that hemolysis during plasma separation can be avoided despite an accelerated procedure.

Publication number: 20030012694Abstract: Disposable unit for single use for the analysis of biological liquids, in particular cell suspensions such as blood, urine, or sperm, with a diluent chamber (5), a sample dosage device (6), and a measuring chamber (7). The sample dosage device (6) has a dosage element (8) into which a dosage capillary (13) is integrated. The dosage element (8) is situated movably in a dosage element chamber (12) in such a manner that one opening (14) of the dosage capillary (13) is connected to a sample loading zone (17) of the disposable unit (2) when the dosage element (8) is in its first position, and when it is in its second position, the diluent chamber (5) and the measuring chamber (7) are connected to one another via the dosage capillary (13). The measuring chamber (7) has a ventilation valve (35) which is permeable to gas but impermeable to the sample liquid, so that the chamber is completely filled free of any bubbles with the liquid (36) flowing into it.Type: ApplicationFiled: March 4, 2002Publication date: January 16, 2003Inventors: Bernd Roesicke, Guenter Frey
