Abstract: A compact apparatus for the extraction and delivery of measured quantities of liquid characterized by a fine adjustment of the stroke of the operating rod whereby accurately controlled measured amounts of liquids may be lifted and delivered is disclosed.

Abstract: A centrifuge chamber for cytodiagnostic investigation of epithelial cells contained in a sample, wherein a cell suspension investigated is placed in a first bore of a sample chamber containing a plurality of bores disposed parallel to one another and subjected to a centrifuging process. During a centrifuging process, the sample fluid is separated into a proximal fraction and a distal fraction, and the proximal fraction is then separated by the centrifuging process so that it is transferred via a flow connection provided between the first and second bores, into the second bore. In addition to automatic separation of the proximal and distal fractions during the centrifuging process, it is also possible to perform a staining procedure during the centrifuging process.

Abstract: The method for sedimentation of part of a sample liquid on a slide by centrifuging a sample tube containing the sample liquid consists in the fact that the separation of the sample liquid into a sedimentation product and a supernatant and the coating of the slide with the sedimentation product is accomplished in a single work step during centrifugation. A plurality of successive work steps of a conventional nature is thereby avoided, because the sample tube containing the sample liquid is designed in the form of a centrifuge tube sealed by a releasable closure, against whose inner end, pointing into the centrifuge tube, the slide is releasably fastened.

Abstract: A cup (2) of the centrifuge has two chambers (1,3). In the first chamber is placed the first blood bag (6) filled with blood fluid, which is inserted into the chamber together with an elastically deformable inset cup (4). A pressure pad (9) bears at one end on the outside (7) of the inset cup (4) and at the other end on the inside (8) of the chamber (1) of the centrifuge. During the centrifuging, the pressure pad (9) is admitted with pressure which results in a great volume increase. The inset cup (4) is thus compressed elastically so that the blood bag (6) is compressed and the blood components centrifuged in the blood bag are transferred corresponding to the volume increase of the pressure pad (9) into an empty satellite-blood bag arranged in the adjacent chamber (2). Over the upper connecting part (81) of the blood bag projecting from the chamber (1) is pushed a holder (64) which prevents bending of the connecting tube during the centrifuging process.

Abstract: The invention is shown as a two part stand having receptacles for holding test tubes. The first, top part comprises a plurality of vertical receptacles for receiving the test tubes in a close fitting relationship. The second, bottom part is a rack that is interconnected to the top part in an easily detachable manner, and it comprises a base plate and vertical corner posts so that it is possible to look through all four sides of the bottom part of the stand and observe the contents of the test tubes.

Abstract: Centrifugal bucket 1, 31 consists of a plastic material 52, in which a U-shaped metal part 2, 32 is imbedded. Receiving grooves 3, 33 for sustaining the pegs of the centrifugal suspension gear are formed in metal part 2, 32, so that in the transmission of the centrifugal force from the bottom of the centrifugal bucket on receiving groove 3, 33 solely the metal part is acting as load transferring connection.

Abstract: An apparatus is disclosed for providing a digital indication of characteristic data measurements of a centrifuge centrifugal head for examining the contents of test vessels, characterized by an indicator capable of showing directly, according to the adjustment of a selector switch, the acceleration, number of revolutions per unit of time and rotor characteristic data.
