Abstract: The invention relates to a procedure for biphasic preparation of liposomes, in the course of which technically simple and cheap mechanical mixing methods are used to commingle non-polar organic phase containing an individual mixture of natural and synthetic phospholipids and polar aqueous (buffer) phase not miscible with it, resulting in a liposome emulsion of a unique structure. Furthermore, the invention comprises embodiments of the procedure related to the in vitro diagnostic use of liposomes prepared in this way, when protein type active components are anchored to the surface of liposome membranes without application of any detergents and non-protein type active components are simply mixed with the liposome emulsion of a unique structure. In one of the possible embodiments of the procedure a Prothrombin Time (PT) reagent is prepared. Another possible embodiment of the procedure is the preparation of an activated partial thromboplastin time (APTT) reagent.

Abstract: Apparatus and processes for automated diagnostic testing may include cuvette dispensing, test sample dispensing, reagent dispensing, incubation, photo-optical measuring, and a control in operative communication with the cuvette dispensing unit, the test sample dispenser, the reagent dispenser, the incubation unit, and the measuring unit. A cuvette removal location, a reagent removal location, a measuring location, and a collection receptacle may be situated along a first common circular arc having first geometric center. A cuvette-moving arm and a reagent-dispensing arm have a common axis of rotation passing through this geometric center. A sampling position, a sample dispensing position, an additional rinsing position, and an additional washing position, may all be provided on a second circular arc having second geometric center that has a second axis of rotation for a rotatable sampling arm of the test sample dispenser.

Abstract: Apparatus and processes for placing sample cuvettes at measuring points, dispensing a reagent into the cuvettes, and forwarding used cuvettes to a receptacle after finishing the measurements. The apparatus has an incubation module (1) for incubating sample cuvettes (7), a reagent module (3) containing a reagent of an amount needed for the assay, and a measuring module (2) favorably accommodating optical measuring points. Arms (K1 . . . KN) can move the sample cuvettes (7).

Abstract: An apparatus and method for the sequential electroelution of biomolecules is described, the apparatus comprising a separation medium having an outlet, and a collector having at least a first receptacle and a second receptacle that can be sequentially brought into contact with the outlet of the separation medium by translating the first receptacle and the second receptacle in relation to the outlet of the separation medium, and the method comprising the steps of receiving a first substantially separated molecule in the first receptacle and translating the first receptacle and the second receptacle such that the second receptacle is brought into in contact with the outlet of the separation medium, receiving a second substantially separated molecule in the second receptacle, and repeating said steps to sequentially receive a desired number of substantially separated molecules.
