摘要:
A capvette for the optical examination of liquids comprises a cuvette component having a rectangular or square basal surface with four side walls terminating into an aperture, wherein said aperture is in communication with a sealable cap component comprising an opening for fluid passageway from a container into said cuvette component. The capvette and container combination, as a single unit allows reaction of fluid or growth of microorganism and measurement of optical density at desired time intervals. A direct method of measuring optical density comprises simply inserting the cuvette component of the capvette into a spectrophotometer.
摘要:
A system for interrogating non-homogeneous liquid samples to locate regions of interest within the samples, and to extract liquid from the regions of interest. The system of the invention is particularly well adapted for use in locating and in thoroughly removing liquid from regions of interest that include even extremely thin, film-like, horizontally extending layers of interest that typically are in the range of about 10 to 50 microns in thickness. The system utilizes a polarized beam of collimated laser light that is projected along a horizontal travel path, that is transmitted through a sample, and that is detected to enable characteristics of the transmitted light beam that have been affected by characteristics of the interrogated sample portions to be studied. By this arrangement, a centrifuged sample of liquid that differs in content at different height levels can be interrogated to locate levels within the sample where one or more layers of components of interest reside that are to be withdrawn from the sample. Withdrawal of liquid components from each such layer is effected by inserting a pipette into the sample to a level where the components reside, and by withdrawing the components through the pipette.

A hemolysis reaction measuring device includes a hemolysis reacting member made of a light transmitting material and adapted to cause hemolysis reaction to take place therein, a light source supported so as to be able to project light toward a side portion of the hemolysis reacting member, and a light receiving member which allows the light emitted from the light source and passing through the hemolysis reacting member to be incident upon it so as to measure light absorbance of a liquid within the hemolysis reacting member based on the intensity of the incident light. The light source is formed by a light emitting diode.

The invention relates to a method and a device for analyzing body fluids (21). A picture recording device (30) is placed in a flare-free room (16) provided with a lighting equipment (45) and is connected to an electronic picture evaluating device. The picture recording device (30) is focused on a container (20) which is in an analysis position (22) and contains the body fluid (21) in order to take at least one picture of the body fluid (21). Said picture is analyzed by picture-evaluating software, whereby the quality and quantity of the body fluid (21) is detected.
摘要:
An apparatus and method for absorbance detection in instrumental situations which have short absorption path lengths, such as microchip type devices, includes modulating the sample beam incident upon a sample cell to improve the sensitivity of the absorbance measurement. The modulation means includes a scanning device arranged to move the sample beam from a first position in which the sample beam is incident upon the sample area to a second position in which the sample beam is incident upon the cell.
