Reaction vessel for luminescence tester and cleaning and separating mechanism thereof

Abstract

The invention discloses a reaction vessel for a luminescence tester and a cleaning and separating mechanism thereof. The reaction vessel is made of a transparent material and is flat, the opening of the reaction vessel is larger than the bottom of the reaction vessel, the reaction vessel is placed in a cleaning turnplate in the circumferential direction, the flat sides of the reaction vessel are in the circumferential direction, a suction pin and a drawing pin are arranged above the reaction vessel, and magnets used for magnetic separation are placed on the flat sides of the reaction vessel so as to attract magnetic bead particles to one side of the reaction vessel fast and prevent the magnetic bead particles from being sucked away by the suction pin during cleaning; to completely remove impurities, the magnets are placed on the two flat sides of the reaction vessel alternately to enable the magnetic beads to move to the other side from one side of the vessel during cleaning, impurities possibly precipitating under the magnetic beads are released, so that the reliability and repeatability of measurement results are guaranteed, the number of times of cleaning is reduced, and testing speed is increased.

Description

technical field [0001] The invention relates to a cuvette for a luminescence measuring instrument and a corresponding cleaning and separating mechanism, in particular to a chemiluminescence immunoassay system. technical background [0002] At present, there are various types of cuvettes for luminescence measuring instruments and their corresponding cleaning mechanisms on the market. Some magnets are far away from the other side of the liquid to be separated, and it is not easy to separate the magnetic beads within a certain period of time. The magnetic bead particles are easily sucked away by the suction needle during the cleaning process, which affects the reliability and repeatability of the results; some magnetic separation is only performed on one side of the cup, and the impurities accumulated under the magnetic beads cannot be released during the cleaning process. , although some systems use methods such as vibration to resuspend the magnetic beads, but the structure i...
