When opened, some of the liquid introduced through the inlet pipe 11 flows into the discharge pipe 1 through the "U" -shaped connecting pipe 9, and some of the liquid flows into the flow measuring pipe 7 and at the same time flows. The control member 12 and the adjustment auxiliary rod 16 and the adjustment rod 13 is continuously introduced into the flow, and thus discloses a technique for accurately measuring and discharging the flow rate discharged from the discharge pipe (1). . However, such a liquid supply device requires a vacuum pump and has a problem in that the device is complicated, so that the production process is complicated, and the cleaning after using the device is also difficult.

In addition, the use of a dropper when a conventional laboratory is to supply a quantitative amount of the reagent, causing the foreign matter or other reagents used in the experiment to be transferred to the reagent through the dropper, causing a change in the concentration and purity of the reagent. In order to solve this problem, the method of reducing the amount of reagent to be used in an experiment such as a beaker is used. However, since the remaining reagent after the experiment has to be discarded after the experiment, it causes resources waste and environmental pollution. It is becoming.

Accordingly, the present invention has been made to solve the above problems, an object of the present invention to provide a liquid volume measuring aid for dropping the correct amount of liquid.

Another object of the present invention is to provide a liquid volume measuring aid capable of supplying various amounts according to the purpose of use.

In addition, another object of the present invention to simplify the structure is to provide a liquid volume measurement aid that is easy to manufacture and reduce the unit cost of the product and easy to wash.

In addition, it is intended to prevent waste of resources and environmental pollution by separating the quantitative liquid to be used from the reagent in the reagent container to keep the reagent to a minimum after the experiment.
