[0002] The solvent filter head and pipeline in the mobile phase reagent bottle of HPLC and HPLC-MS are connected to filter the particulate impurities in the mobile phase. When the mobile phase is re-prepared, the solvent filter head and pipeline are taken out of the reagent bottle together and usually placed in an open container. The solvent on the solvent filter head evaporates, especially the organic solvent evaporates quickly, and the filter head will enter the air. When it is used again, bubbles will form and enter the pipeline. Sometimes bubbles will continue to form, affecting the experiment. In addition, the solvent filter head is exposed to the air and is easily contaminated.

[0003] Meanwhile, multiple solvent filter heads are stored one by one in an open container, which takes up space and is messy. If multiple solvent filter heads are placed in one container, the pipes are easily entangled, making it inconvenient to take them out.

The solvent filter head is placed during the replacement of the mobile phase or the shutdown of the instrument to avoid contamination of the filter head and the entry of air, and it is more convenient to take.
