Embodiment 1

[0022] Such as figure 1 As shown, the liquid-taking device with adjustable liquid-taking volume of the present invention includes a cylindrical tube 1 with a fully open top, a through hole is provided at the bottom of the cylindrical tube 1, and a quantitative tube 2 is connected below the through-hole. The tube 2 and the cylinder 1 are flexibly connected by a connecting tube 3, the connecting tube 3 is provided with a first control valve 4 for controlling the conduction of the connecting tube, and a liquid outlet pipe 5 is connected below the metering tube 2, and the liquid outlet pipe The lower end of the 5 is a liquid outlet, the lower end of the liquid outlet pipe 5 is a tip, the liquid outlet pipe 5 is provided with a second control valve 6 for controlling the conduction of the liquid outlet pipe, and the cylinder wall of the cylindrical cylinder 1 is provided with a tick marks. Both sides of the cylinder 1 are connected with vertical support rods 10 , the two support ro...

Embodiment 2

[0025] Based on Embodiment 1, an upwardly inclined arc tube 7 is connected to the top of the cylindrical tube 1, and the nozzle of the arc tube 7 located below is connected with the opening at the top of the cylindrical tube 1 and communicates with each other. The diameter is equal to the diameter of the opening at the top of the curved tube 7, and the nozzle above the curved tube 7 is provided with a sealing gasket 8 that completely covers the nozzle. through vias 9.

[0026] The arc-shaped tube and the sealing gasket play a guiding role for the reagent, avoiding the leakage of the reagent and causing safety problems when pouring the reagent into the cylinder. When pouring liquid, insert the bottle mouth of the reagent bottle through the through hole into the arc top tube, and the reagent will not leak out when the reagent is obtained.

Abstract

The invention discloses liquid getting equipment with an adjustable liquid getting amount. The liquid getting equipment comprises a cylinder, wherein the top of the cylinder is completely opened, wherein a through hole is formed in the bottom of the cylinder; the lower side of the through hole is communicated with a quantitative tube; the quantitative tube is movably connected with the cylinder through a connecting pipe; the connecting pipe is provided with a first control valve for controlling the connecting pipe to be conducted; the lower side of the quantitative tube is connected with a liquid outlet pipe; the lower end of the liquid outlet pipe is a liquid outlet end; the lower end of the liquid outlet pipe is a sharp end; the liquid outlet pipe is provided with a second control valve for controlling the liquid outlet pipe to be conducted; scale lines are arranged on a cylinder wall of the cylinder. According to the liquid getting equipment with the adjustable liquid getting amount, disclosed by the invention, the cylinder with the capacity and diameter, which are greater than that of an existing measuring cylinder, is adopted and the problem that a reagent is dropped out in an existing measurement process is solved, so that the safety problem in the prior art that quantitative liquid getting of a toxic reagent in organic synthesis is solved.

Description

technical field [0001] The invention relates to a liquid-taking device, in particular to a liquid-taking device with adjustable liquid-taking volume. Background technique [0002] Organic reactions are chemical reactions involving organic compounds and are the basis of organic synthesis. Several basic reaction types are: substitution reactions, addition reactions, elimination reactions, pericyclic reactions, rearrangement reactions, and redox reactions. Reagents used in organic reactions are also a hot topic of research. They are often used in specific reactions, such as: ① oxidizing agents, such as osmium tetroxide, potassium permanganate, m-chloroperoxybenzoic acid; ② reducing agents, such as lithium aluminum hydride, Raney nickel, sodium borohydride; ③ Alkali, such as lithium diisopropylamide, sodium hydroxide; ④ acid, such as sulfuric acid; ⑤ catalyst, etc. [0003] Organic reactions contain a large number of organic reagents. Organic reagents can be used as indicator...
