Description

technical field

[0001] The invention relates to the field of configuration devices, in particular to a configuration device for buffer solvent preparation. Background technique

[0002] The Chinese patent with the publication number CN108772001A discloses a solution configuration device, which includes a diluent pipe, a raw material tank and a solution mixing tank. The body is connected, and both the water inlet pipe and the discharge pipe are in fluid communication with the diluent pipe. The solvent configuration device can realize sufficient mixing of solvent and solute, and effectively prevent solution stratification.

[0003] However, when the solution configuration device is used to configure the buffer solution, since the buffer solution refers to a mixed solution composed of a weak acid and its salt, a weak base and its salt, it can offset and alleviate the external strong acid or strong base to a certain extent. The impact on the pH of the solution, so as to keep t...
