The application relates to the technical field of separatory funnels, in particular to a sealing structure of a separatory funnel piston. A piston rod is arranged in a separation pipe of a funnel bottle body, one end of the piston rod is sealed and combined with the end face of the separation pipe, a connecting end is formed at the end of the piston rod penetrating through the separation pipe, a step is formed at the connecting position between the piston rod and the connecting end, a sealing assembly is sleeved on the connecting end, a locking piece is installed at the connecting end, the sealing assembly is tightly combined with the end face of the separation pipe and the end face of the step through the locking piece, the gap between the separation pipe and the piston rod is sealed, the problem that solution leakage is caused by piston rod loosening during the test process is avoided, the sealing effect is improved, and the stability of the separatory funnel sealing is ensured.

This application discloses a separating funnel. The separating funnel includes a lower platform end with a first through-hole in the center. The inlet end of a three-way separating assembly is detachably connected to the platform end to connect the three-way separating assembly to the first through-hole. A sealing cap is detachably connected to the platform end to seal the first through-hole after the three-way separating assembly is separated from the platform end. The bottom of the platform end has a support portion configured to support the bottle body after the platform end and the three-way separating assembly are separated, and / or, the support portion is configured to support the bottle body when the platform end and the sealing cap are connected. The separating funnel has functions such as liquid separation, reaction rate control, extraction, and purification. Furthermore, the bottle body can be used as a measuring cylinder, vacuum filtration flask, reagent bottle, etc. The separating funnel has at least two uses, solving the problem of single-use of the separating funnel and improving its utilization rate.
