Configuration device for preparing buffer solvent

Abstract

The invention discloses a configuration device for preparing a buffer solvent. The device comprises a base, a rotating frame rotatably mounted on the base, a first rotary driving device, a first mounting frame arranged on one side of the rotating frame, a quantitative dropping pipette mounted on the first mounting frame, a second mounting frame mounted on the other side of the rotating frame, a lifting driving device, a top cover, a stirring device and a second rotary driving device, wherein a central hole is formed in the middle of the top cover, and the stirring device is arranged in the central hole of the top cover in a penetrating manner; the second rotary driving device is mounted on the second mounting frame and is used for driving the stirring device to rotate; a liquid adding area, a first container placing area, a stirring device cleaning area and a second container placing area are formed on the base. The configuration accuracy can be improved, the time can be saved, and the efficiency can be improved; in addition, operation is easy and convenient, participation of operators can be reduced, and therefore the workload of the operators can be reduced.

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...

Problems solved by technology

In the process of configuring the buffer solution, a certain amount of buffer is added to the configuration container, and then a certain amount of pure water is added to mix to form a buffer solvent. Too much or too little will result in poor configuration accuracy, which will affect the use

Although there are new dispensing devices on the market that can improve the accuracy of dispensing, when more cups of buffer solution need to be prepared, the new dispensing device needs to accurately add a certain amount of pure water to the previous dispensing container, and after the stirring is completed, In order to accurately add a certain amount of pure water to the next cup of configuration container, and then stir it, and continue to work in the above way to complete the configuration of multiple cups of buffer solution, but it often takes a long time, resulting in low efficiency and far from meeting the needs of the industry
