FIELD: measurement.
SUBSTANCE: present invention relates to devices for analysing substances based on an X-ray fluorescence method, in particular to a measuring cuvette for a liquid sample used in a sample supply device. Measuring cuvette for a liquid sample comprises a housing having an open end and a closed end, crimping ring for fixing the radiolucent film, which is removably mounted on the open end, on which the container for holding the sample is made, and ventilation means located at the closed end. Ventilation means comprise a ventilation hole passing along the wall of the housing in its longitudinal direction, in which there is a removable plug-valve made with possibility of rotation, as well as a support surface located on the outer side of the housing, opposite to the side on which the ventilation hole is made.
EFFECT: high accuracy and reliability of measurement.
