摘要: A photometer for determining the transmission of a liquid sample in a microcuvette (7, 20, 22) has a cavity for a capillary layer of the liquid sample with a free liquid surface extended transversely of the principal plane of the cavity. The cavity is initially prepared with a reagent to achieve a reaction, which affects the transmission of the liquid sample for indicating its contents of a predetermined substance. The photometer has a holder (6) for the microcuvette and measuring means (9, 10) for measuring the transmission of a bundle of rays directed towards the microcuvette. The cuvette holder (6) is mounted on bearings for vibration in a direction having a component, which extends in the plane of the free liquid surface and is parallel with the principal plane of the cavity, thereby achieving a mixing to accelerate the dissolution and the reaction.

摘要: The invention relates to a method for carrying out mixing in a thin liquid layer, which is arranged between essentially parallel walls at a capillary distance from each other. The mixing is carried out by subjecting the walls to a motion essentially in the plane of the liquid layer, balancing the motion against the capillary force exerted by the walls on the liquid, and selecting the interface between the liquid layer and the surrounding medium so that it functions as an elastic membrane. The invention also concerns a cuvette which is designed for mixing according to the method.

摘要: A method for hemoglobin determination is described which includes the steps of introducing a sample of undiluted whole blood by capillary action into a disposable microcuvette having at least one cavity for receiving the sample. The cavity includes a dry essentially non-hygroscopic hemolysing agent, which is dissolved by the blood, hemolyses the red blood cells and releases the haemoglobin contained in the blood cells. A first absorption measurement at a wavelength range 490-520 nm is then performed directly on the sample in the microcuvette, and a second absorption measurement is performed to compensate for background interference.
