Description

TECHNICAL FIELD

[0001] The utility model relates to centrifugal equipment technical field, concretely relates to a centrifugal equipment for inspection. BACKGROUND

[0002] The centrifuge of the clinical laboratory is mainly used for centrifugal separation to samples so as to subsequent inspection and analysis. Through the action of centrifugal force, the components of different densities in the mixture can be separated, and the target component is deposited at the bottom of the sample tube, so that the subsequent inspection or analysis work is facilitated.

[0003] In the prior art, the centrifuge cannot effectively clamp test tubes of different sizes. First, the inappropriate size of the test tube may cause the test tube to be unable to be stably fixed in the notch of the centrifuge during centrifugation. This will increase the risk of test tube falling off or breaking during centrifugation, thereby causing a safety hazard to the experimental personnel. At the same time, the breakage of the test tube may also cause the contamination or loss of the sample, affecting the accuracy and reliability of the experiment. Secondly, due to the mismatch of the test tube size, the centrifuge may not be able to uniformly clamp the test tube. This will cause the test tube to be subjected to uneven centrifugal force during centrifugation, thereby affecting the separation effect of the sample. Uneven clamping may also cause the test tube to vibrate or produce noise during centrifugation, which adversely affects the stability and service life of the centrifuge. In addition, the inappropriate size of the test tube may also limit the use range of the centrifuge. Different sizes of test tubes require different models of centrifuges to adapt. If the centrifuge cannot effectively clamp test tubes of different sizes, multiple models of centrifuges need to be purchased to meet the needs of different experiments. This not only increases the experimental cost, but also reduces the experimental efficiency. SUMMARY
