Abstract
A method for checking the operation of a laboratory instrument used in biochemistry by means of an individual test plate (10) by comparing measured values of sample units (20, 21) placed in the wells (12) of the frame plate (11) to previously known measured values verified by a reference device. The sample unit (20) placed in the frame plate (11) of the test plate (10) is a teflon plastic cup (22) provided with an aluminum cover (23), the sample material (24) in powdery form being placed in said cup, or an optical filter (21), which is locked in place by means of a locking spring ring (25).
