Abstract: The invention relates to a simple and rapid method for the detection of cells and biomolecules by means of paramagnetic particles (beads) without separating the detected biomolecules or target cells from the beads before evaluating the specific bond.

Abstract: The invention relates to the use of specific ligand carriers for detecting prions, and to substances that are capable of binding to prions and that are subsequently used to detect prions.

Abstract: An apparatus for determining the viscosity of fluids, particularly blood plasma, includes an outer housing including a front surface having a groove therein; a disposable capillary tube removably mounted in the groove and including at least one loop, each of the loops having two substantially horizontal branches including an upper branch and a lower branch for flowing the fluid under the influence of gravity through a predetermined path, and a device for measuring the rate of flow of the fluid along the path in one of the horizontal branches. Also disclosed is a flexible disposable capillary tube for the fluid viscosity measuring apparatus.

Abstract: The new instrument for taking readings of the hematocrit value from a blood sample has two electrodes with which the conductivity of the sample may be measured. The sample contacting faces of the electrodes are placed in a horizontal plane with an accurately fixed spacing therebetween so that a blood column of a given size may be formed from the sample. The sample is acted upon by ac. From a reading representative of the change in impedance the hematocrit value may be read off from a calibration curve.

Abstract: For measuring the deformation capacity of erythrocytes use is made of a sample vessel that is walled off into two spaces by a piece of foil with a pore therein. One such space is filled with buffer solution with erythrocytes and the other is filled with buffer solution without erythrocytes. A pressure head is produced acting across the foil for causing transit or passage of the erythrocytes through the opening, whose diameter is less than the major quiescent diameter of an erythrocyte so that information on the deformation capacity may be produced by measuring the transit time. This is done by electrodes placed on the two sides of the opening so that changes in the resistance to alternating current by an erythrocyte in transit may be sensed and the transit time taken. After about 200 transits the readings are processed in a processing unit.

Abstract: The invention concerns a measuring apparatus for checking and determining the flow shear stress of certain suspensions, principally blood, by a static or dynamic method and to thereby plot the viscosity of the suspension. The apparatus employs an internal measuring chamber comprised of a passage arrangement to simulate the natural microcirculation area wherein a network of capillary passages diverge from a main passage, with at least two of the capillary passages of different lengths, with a length ratio that can range from 3:1 to 15:1, with those capillaries connected to a source of variable pressure and extending past a detector unit.

Abstract: A test value corresponding to blood subsidence from a syllectogram is determined as a result of the effect of shearing forces on a blood sample, by ascertaining the slope of the test curve representing the syllectogram at a predetermined time beginning with or after the onset of the blood aggregation phase as the test value after:(a) sudden stoppage of the shearing; or(b) a transition to a continuous minor residual shearing.
