Sampling tube

The utility model discloses a sampling tube. The sampling tube comprises a sealing cover, a tube cover and a tube body which are connected in sequence, a sample extracting solution is preloaded in the tube body; a filter plug is arranged in the tube cover and is used for filtering a sample extracting solution containing a sample. After sampling, opening the tube cover, inserting the head of the disposable sampling swab into a sample extracting solution, releasing the sample into the sample extracting solution, and covering the tube cover; the sealing cover is opened, so that the sample extracting solution carrying the sample flows out through the filtering plug and is poured into the sample cup for detection; compared with a traditional centrifugal sampling tube mode, the filter plug can better change the state of the sample, so that the sample and the sample extracting solution are fully mixed, and the detection accuracy is further improved. Therefore, the sampling tube provided by the utility model can impr
