Abstract: The invention relates to a laboratory analyser unit (10) for determining an analyte of a reagent-mixed liquid sample (48) contained in a transparent sample cuvette (40) comprising an information carrier (44) with an optical cuvette label (46), comprising an analyser (12) for determining an analyte concentration of the liquid sample (48) in the sample cuvette (40), a reading device (30) for reading the cuvette identification (46), an instrument controller (20) which, from the cuvette identification (46) read out by the reading device (30), generates a liquid sample level setpoint (SP), wherein the device control (20) comprises a liquid sample level detection (26) signal-connected to a camera (30?), which determines a liquid sample level actual value (IP) of the liquid sample (48) in the transparent sample cuvette (40) from the camera signal, and wherein a level comparison module (28) is provided which compares the determined level setpoint (SP) with the determined level actual value (IP).

Abstract: The invention refers to a method for determining a cuvette form correction value (F) for a laboratory analysis cuvette (10) filled with a liquid reagent (60) and having a transparent cuvette body (12) comprising a vertical wall (14) and a bottom wall (13), comprising the method steps: Determining the liquid reagent volume (V) of the liquid reagent (60) filled into the laboratory analysis cuvette (10), optically determining the liquid reagent level (H) of the liquid reagent (60) in the laboratory analysis cuvette (10) by a level determination camera (24), calculating a horizontal inner width (D) of the laboratory analysis cuvette (10) from the determined liquid reagent volume (V) and the determined liquid reagent level (H) by an electronic control (26), and calculation of the form correction value (F) from the calculated horizontal inner width (D) and a reference inner width (D?) of the laboratory analysis cuvette (10) by the electronic control (26).

Abstract: Various turbidimeters are described that can detect light directly in a substantially circular, e.g., encompassing, manner such that an increased amount of scattered light from a sample vial may be detected by a light detector, e.g., a photodiode or photodiode array. In an embodiment, a substantially circular photodiode array is provided to directly detect scattered light in an arc about the sample vial. In other embodiments, light guides are provided in an arc element that guides light to a detector or detectors. Other aspects are described and claimed.
