Patent ID: 10016758

Abstract:
An automatic analyzer cartridge spinnable around a rotational axis has a fluid chamber for receiving a fluid, an aliquoting chamber, a duct connecting the fluid chamber and the aliquoting chamber, a downstream fluidic element, a siphon for siphoning the fluid from the aliquoting chamber to the downstream fluidic element, a fluidic structure for processing a biological sample into the processed biological sample, and a measurement structure for enabling measurement of the processed biological sample. The siphon has a siphon entrance in the aliquoting chamber and a siphon exit in the downstream fluidic element, wherein the siphon has a bend, wherein the bend is the portion of the siphon closest to the rotational axis, wherein the siphon entrance starts at the bend, wherein the siphon entrance extends to a lower portion of the aliquoting chamber. This enables multiple aliquots of fluid to be removed from the aliquoting chamber by the siphon.
