Problems solved by technology
When the existing separatory funnel separates the lower layer liquid, it is necessary to place a beaker and other containers under the funnel. At the same time, in order to prevent the upper layer solution from flowing out, the whole process of separating the lower layer solution requires the operator to observe and wait carefully, which affects the need for quantitative separation in large quantities. Extraction operation efficiency of lower liquid

Embodiment Construction
[0011] A U-shaped separating funnel used in the extraction process of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0012] figure 1 A kind of U-shaped separating funnel of the present invention that is used for extraction process as shown comprises A pipe 2 as mixed extraction and B pipe 3 as liquid pipe, and the upper nozzle of described A pipe 2 has ground plug 1, The bottom of pipe A 2 is provided with a cock 6 , and the liquid outlet below the cock 6 communicates with the bottom of pipe B 3 through a U-shaped glass tube 7 .
[0013] During operation, first close the cock 6, move the extracted two phases into the A tube 2, cover the ground plug 1, and then carry out the mixing or extraction operation. After stratification, open the cock 6, and the lower layer solution 6 can pass through the U-shaped tube 7 quickly. Enter B tube 3, the solution in B tube 3 can be used for direct meas...

The invention discloses a U-shaped separating tunnel used in an extraction process. The U-shaped separating tunnel comprises a tube A used for mixing extraction and a tube B used as a distribution tube, wherein a ground-glass stopper is arranged on an upper pipe orifice of the tube A, a cock is arranged at the bottom of the tube A, a liquid outlet below the cock is communicated with the bottom of the tube B through a U-shaped glass tube. The separating tunnel has the advantages of being simple in structure, low in cost and convenient and fast to operate, can reduce time spent in observing or waiting during an operation of unfixed quantity lower solution separation, thus improving efficiency in the operation of the unfixed quantity lower solution separation. Compared with a traditional separating tunnel, the U-shaped separating tunnel is obviously more convenient and fast, and is particularly applicable to a chemical analysis operation of components ready to be measured in the lower solution after directly using a device to conduct measurement and extraction.
Description
technical field [0001] The invention relates to a chemical experiment vessel, in particular to a separatory funnel used for non-quantitative and rapid separation of lower layer liquid in a liquid-liquid extraction process. Background technique [0002] Separating funnels are commonly used in chemical analysis to extract, separate or purify substances. When the existing separatory funnel separates the lower layer liquid, it is necessary to place a beaker and other containers under the funnel. At the same time, in order to prevent the upper layer solution from flowing out, the whole process of separating the lower layer solution requires the operator to observe and wait carefully, which affects the need for quantitative separation in large quantities. The extraction operation efficiency of the lower liquid. Contents of the invention [0003] The object of the present invention is to provide a U-shaped separatory funnel for the extraction process with simple structure, low c...
