Abstract: The invention relates to a device for inspecting eggs for the presence of blood. The device comprises a light source in order to pass light at a first wavelength which is not selectively absorbed by blood and light at a second wavelength which is selectively absorbed by blood through an egg to be inspected. Furthermore, the device comprises detection means for converting the light transmission through the egg to be inspected for each of the two wavelengths into corresponding signals, each of the said signals being representative of the light transmission at the relevant wavelength. The device also comprises signal-processing means which are designed to determine the ratio between the light transmission associated with the first wavelength and the light transmission associated with the second wavelength based on the signals emanating from the detection means and to emit a decision signal which is representative of the decision whether or not an egg contains blood on the basis of this ratio. According to the invention, the light source comprises one or more identical LED' s (Light Emitting Diode) for generating light which passes through the egg. In use the one or more LED' s emit light within a certain narrow spectrum, which spectrum comprises both the first and the second wavelength.

Abstract: A sample of whole blood is contacted with a reagent which by chemical reaction with glucose in the sample brings about a detectable dye concentration change (10) the size of which is determined as a measure of the glucose content of the sample. The sample is initially introduced undiluted in a microcuvette having at least one cavity for receiving the sample. The cavity is internally pretreated with the reagent in dry form, and the chemical reaction takes place in the cavity. Active components of the reagent comprise at least a hemolysing agent for exposing glucose contained in the blood cells of the sample for allowing total glucose determination, and agents taking part in the chemical reaction and ensuring that the dye concentration change (10) takes place at least in a wavelength range (14) outside the absorption range (12) of the blood hemoglobin. An absorption measurement is performed in said wavelength range directly on the sample in the cuvette. A pretreated disposable cuvette with such a reagent and a photometer are also described.

Abstract: Process and device for measuring gloss in a surface with a light source, which emits light towards the surface, and with a photosensitive detector, which receives the light reflected by the surface and converts it into an electrical signal value. Said device includes a storage unit, where a computing rule for calculating the gloss parameter is stored, a calculation unit, which determines a gloss parameter on the basis of the electrical signal value using the computing rule, and a display unit, which displays the gloss parameter calculated. Five or more pairs of reference values are stored in the storage unit, each pair of reference values being comprised of a reference gloss parameter and of a corresponding reference signal value measured by the device using a reference surface. A comparative unit is also provided, which compares the signal value measured with said reference signal values and feeds at least the nearest higher and the nearest lower value to an interpolation unit.
