Abstract: A sample vessel matrix is provided in which the walls of the individual sample vessels are very high compared with their cross-section, wherein the ratio of the height of the sample vessel to the well length is between 3 and 7.

Abstract: Spherical, magnetizable polyvinyl alcohol microparticles, methods for their production, and use thereof are provided in the invention. The microparticles are especially useful for diagnostic purposes. The method enables the production of microparticles having a particle size distribution in the range of 0.5 to 3 ?m, and includes the following steps, dispersing a nanoparticulate, magnetizable material in an aqueous phase which contains polyvinyl alcohol in dissolved form, adding the aqueous phase to an organic phase, immiscible with said aqueous phase and containing at least one emulsifier, producing an emulsion by stirring at a temperature of 25° C. or higher, and adding at least one water-soluble crosslinking agent while stirring is continued.

Abstract: A device is provided for the complete uptake of liquids from vessels using removal units having removal tips. The removal tips or the vessel bottoms are configured or arranged relative to one another such that the area of the surface of a vessel bottom on which the respective removal tip would touch down, when that removal tip is inserted into the vessel, and the end surface of the removal tip are tilted relative to each another, at least on a portion of the two surfaces. That is to say, the surfaces are not parallel there.

Abstract: A device (10) is provided for separating magnetic or magnetizable particles from a liquid by using a magnetic field. The device includes a head piece (3) with one or more magnetizable bars (4) which is/are permanently or detachably connected with the head piece (3), as well as one or more permanent magnets (1) whose relative position with respect to the head piece can be changed by a predeterminable movement of the magnet(s) or/and by a predeterminable movement of the head piece.

Abstract: A device is provided to separate magnetic or magnetizable particles from a liquid by using a magnetic field. The device includes two limbs made of a soft-magnetic material. An air gap is provided between be two poles of the limbs. The air gap can receive one or more liquid containers. A head piece is arranged in a fixed or detachable manner on one of the two poles. One or more magnetizable bars are disposed in a fixed or movable manner on the head piece, in the vertical direction. One or more permanent magnets are arranged in a movable manner on at least one point of the device, such that a magnetic field can be produced between the two poles and the magnetic field can be activated or deactivated by moving the magnet(s). The region of the device where the movable magnet(s) are arranged is at least partially surrounded by a material that screens the magnetic field.

Abstract: A device for treating magnetizable or magnetically attractable particles which are present in a liquid, comprising a holder for one ore more reaction vessel(s) with the liquid containing the particles, at least two movably arranged permanent magnets, a drive unit for moving the permanent magnets; with the permanent magnets being arranged in pairs and opposite each other, and being movable in vertical direction (a, b), and the distance between the two permanent magnets of a pair being dimensioned or adjustable such that a reaction vessel can be positioned therebetween.
