[0003] However, in the prior art, after the sample needle is cleaned, liquid tends to remain on the surface of the sample needle, resulting in the phenomenon of hanging liquid. In this way, the residual liquid will pollute the sample or reagent drawn during use, or affect its concentration, etc., thereby affecting Test accuracy

The embodiment of the invention provides a method for preventing a sample adding needle from hanging liquid, and relates to the technical field of cleaning methods. The method for preventing the sample adding needle from hanging the liquid comprises the steps that the sample adding needle stretches into a cleaning pool at a first preset speed, then the sample adding needle is lifted at a second preset speed till the sample adding needle is lifted to enable the lower end of the sample adding needle to be located above the liquid level by a first preset distance, and then the sample adding needle is lifted at a third preset speed, so that the sample adding needle is prevented from hanging the liquid, wherein the first preset speed and the second preset speed are both smaller than the third preset speed, that is to say, when the sample adding needle is lifted, a slow-first and fast-second manner is adopted, and the liquid hanging phenomenon on the surface of the sample adding needle can be effectively prevented.
Description
technical field [0001] The invention relates to the technical field of cleaning methods, in particular to a method for preventing liquid from hanging on a sampling needle. Background technique [0002] In the operation involving biochemical tests such as genetic testing, it is often necessary to use a sample needle to transfer reagents or samples. After the sampling needle is finished adding samples, in order to avoid cross-contamination between different samples or reagents, it is necessary to clean the sampling needle before the next sample or reagent. [0003] However, in the prior art, after the sample needle is cleaned, the surface of the sample needle tends to remain liquid, resulting in the phenomenon of hanging liquid. In this way, the residual liquid will pollute the sample or reagent aspirated, or affect its concentration, etc., thereby affecting Test accuracy. Contents of the invention [0004] The object of the present invention includes, for example, to prov...
