Abstract
The invention discloses a secondary extraction separating funnel for a laboratory. The funnel structurally comprises a feed chute, a connector, a filter pipe, a display panel, an upper extraction layer bottle body, a lower extraction layer bottle body, scale lines, a lower outlet pipe, a rubber filling block, a clamp shaft, a liquid outlet, a turning knob and a label, the display panel is provided with a liquid level sensor, a working indicator lamp, an outer cover, a display screen and a storage battery, the outer cover is connected with the upper extraction layer bottle body, the liquid level sensor is connected with the upper extraction layer bottle body through the outer cover, the display panel is mounted on the surface of the outer cover, and the storage battery is mounted on the inner lower portion of the outer cover. The funnel has the advantages that electronic reading effects can be achieved by the aid of the display panel, solution height in a container can be displayed, naked eye reading errors are avoided, usage of extracted solution is exactly rated usage of other experiments, the other experiments can be smoothly performed, and experimental quality is improved.
Description
technical field [0001] The invention is a separating funnel for secondary extraction in a laboratory, which belongs to the field of chemical experiment equipment. Background technique [0002] A separatory funnel is a glass experimental instrument, especially a separatory funnel for chemical experiments. It includes a bucket body and a bucket cover covering the upper mouth of the bucket body. A piston with a three-way structure is installed at the lower opening of the bucket body, and the two-way connections of the piston are respectively connected with the two lower pipes. Practical use can make the experimental operation process easy to control and reduce labor intensity. When the amount of liquid to be separated is large, only need to move the tee of the piston to flow the two liquids in the bucket to the lower tube at the same time, without changing the container. Can be done in one go. The main function of the separatory funnel in junior high school is to control the...
