[0016] 1. Compared with the prior art, the centrifuge adapter for preventing cross contamination in the clinical laboratory can seal the specimen solution in the container assembly twice through the mortise and tenon assembly, prevent the leakage of the solution due to damage of the specimen container or poor sealing between the specimen container and the rubber container plug, or the destruction of the sealing property of the contact part between the specimen container and the rubber container plug when the centrifuge is centrifuging the specimen container, and thus cause cross contamination of the specimen solution.

[0017] 2. Compared with the prior art, the centrifuge adapter for preventing cross contamination in the clinical laboratory can control the number of specimen containers that need to be centrifuged through the connecting groove and the connecting block of the fixed mold. When the specimen solution to be measured is less, the workers can remove part of the excess fixed mold through the connecting groove and the connecting block, so as to reduce the burden of the rotor and the centrifuge bearing when the centrifuge is centrifuging, thereby prolonging the service life of the equipment. Since the power for driving the rotor to accelerate and maintain the speed is positively related to the weight of the centrifuge load, when a certain amount of fixed mold is reduced, the operating power of the centrifuge motor is also reduced, thereby achieving the purpose of energy saving and consumption reduction.
