Description

TECHNICAL FIELD

[0001] The utility model relates to the field of stirring beaker, more specifically, to a stirring beaker capable of conveniently measuring specific gravity. BACKGROUND

[0002] In the process of preparing liquid preparation in the laboratory, the specific gravity of the liquid often needs to be measured after preparation. In this operation process, specific gravity measuring instruments are required.

[0003] The conventional stirring beaker currently only supports the preparation of liquid preparation. When the specific gravity needs to be measured, the liquid needs to be transferred to a constant-volume bottle for weighing or to a special long-tube container for specific gravity measurement with a specific gravity measuring meter. This operation process will increase the number of containers and equipment used, resulting in a large number of containers and equipment that need to be cleaned after the test, and a large amount of cleaning work. In the process of liquid transfer, "dropping" and "leaking" phenomena often occur, which will pollute the working environment, cause chemical leakage, and affect the safety of the experimenters. In addition, the evaporation of some solvents during the preparation of liquid preparation is large, which will affect the accuracy of the preparation and the result of the specific gravity measurement. Therefore, improvement is urgently needed. SUMMARY

[0007] As a further description of the above technical scheme, the piston mechanism comprises a push rod and a rubber piston block, the bottom end of the push rod being fixedly connected to the top of the rubber piston block, and the outside of the rubber piston block sliding into the inside of the cup body.

[0008] As a further description of the above technical scheme, a rubber plug is inserted into the top end of the specific gravity measuring cylinder.

[0012] Compared with the prior art, the utility model has the advantages that:

[0013] The present application uses the piston mechanism in cooperation with the specific gravity measuring cylinder, which facilitates the direct transfer of the liquid to the inside of the specific gravity measuring cylinder, one-time operation, thereby realizing the device with the advantages of one-time completion of liquid preparation and specific gravity determination, avoiding frequent replacement of utensils, reducing the number of equipment used, shortening the test time, and preventing solvent evaporation during preparation.

[0022] In this invention, the cup body 1 serves as the main body of the device. During use, the piston mechanism 2 is first pulled out from inside the cup body 1. Then, the liquid preparation and stimulating block are placed inside the cup body 1. The beaker is then placed on a magnetic stirrer for stirring. After stirring, the piston mechanism 2 is inserted back into the cup body 1, and the stirred liquid is squeezed into the specific gravity measuring cylinder 3. The specific gravity meter 5 is then removed and inserted into the specific gravity measuring cylinder 3 to measure the liquid specific gravity.

[0025] Please see Figure 1 and Figure 2 Among them, a rubber plug 31 is inserted into the top port of the specific gravity measuring cylinder 3.

[0026] In this invention, the rubber stopper 31 is used to seal the specific gravity measuring cylinder 3 to prevent liquid from spilling out during stirring.
