[0002] A sample bottle is a laboratory tool commonly used to hold liquids during an experiment, and has a closed cylindrical shape. Currently, the caps of common sample bottles have a single function, which is mainly to seal the sample bottle to prevent the sample from leaking or being contaminated during the experimental operation. However, when conducting tests such as continuous sampling analysis, it is necessary to continuously add internal standard solutions or other reagents through the injection tube, and the existing sample bottle cap design does not provide an effective solution to fix the injection tube. Not using a cap will cause too much environmental pollutants to enter the sample bottle, and directly leaving the cap open will make the injection process susceptible to interference from other experimental operations, causing the position of the injection tube to move, and may even cause the injection to be interrupted, affecting the accuracy and stability of the experimental results.
