[0002] Chromatographic technology has a very wide range of applications in analytical chemistry, organic chemistry, biochemistry and other fields, and can be applied to food, medicine, environment, life sciences and petrochemicals and other fields. In chromatography, the mobile phase carries the components to be tested and moves forward. The mobile phase is liquid or gas. The stationary phase is arranged on a fixed carrier to separate the components to be tested. The mobile phase is contained in a mobile phase bottle. A circular hole is provided on the bottle cap of the mobile phase bottle. The mobile phase is led out through a suction filter head and a catheter. The existing mobile phase bottle often has the following problems during the experiment: First, the temperature of the mobile phase will gradually decrease to the room temperature of the laboratory during the experiment, and it is difficult to maintain a suitable experimental temperature; second, in the prior art, when the catheter is placed in the mobile phase bottle, the suction filter head needs to be disassembled or installed. In the process of disassembling or installing the suction filter head, the suction filter head is easily contaminated or the interface between the suction filter head and the catheter is loosened.
