Description

A reagent bottle for quantitatively measuring solution

technical field

The utility model relates to the field of laboratory containers and the field of precise measurement, in particular to a reagent bottle for quantitatively measuring solutions.

Background technique

During the experiment, the reagent bottle only plays the role of containing the solution. When measuring the solution, generally the solution is first poured into the graduated cylinder for reading, so as to achieve the effect of measuring. This often increases the experimental time, and possible impurities in the graduated cylinder will lead to inaccurate experimental results. Therefore, inventing a reagent bottle that can quantitatively measure the solution can shorten the experiment time, reduce the probability of other impurities entering the solution during the experiment, and make the experiment result more accurate. Also avoid the loss of solution in the process of pouring solution.

Contents of the invention

Aiming at the deficiencies in the prior art, the utility model provides a reagent bottle for quantitatively measuring the solution. The moving distance of the push rod is controlled by adjusting the height of the piston sleeve, thereby driving the movement of the piston. Under the principle of pressure, quantitative The solution flows out from the outlet pipe.

The utility model realizes above-mentioned technical purpose by following technical means.

A reagent bottle for quantitatively measuring solution, including a bottle cap, a bottle body, a push rod and a liquid outlet tube; the bottle cap and the bottle body are connected by threads; the piston sleeve is threaded at the mouth of the bottle cap, and one end of the piston sleeve The mouth of the bottle cap protrudes; one end of the push rod passes through the piston sleeve and enters the bottle body to connect with the piston, and the piston fits closely with the inner wall of the bottle; the other end of the push rod is provided with a protrusion, and the The outer diameter of the protrusion is larger than the inner diameter of the piston sleeve; the liquid outlet pipe is located outside the bottle body, and one end of the liquid outlet pipe communicates with the inside of the bottle body, and quantitative marks are arranged on the push rod below the protrusion .

The piston is made of rubber material, and the outer surface of the piston is coated with anti-corrosion paint.

The anti-corrosion coating material is epoxy resin.

The distance between the protrusion and the top of the push rod is 5-10mm.

The quantitative marking is a scale, and the readings of the scale increase sequentially along the push rod to the piston.

The beneficial effects of the utility model are:

1. The reagent bottle for quantitatively measuring the solution described in the utility model has a protrusion at the other end of the push rod, which can directly measure the solution, which reduces the steps of measuring with a measuring cylinder and avoids the process of measuring with a measuring cylinder. The loss of medium solution reduces the experimental error and makes the experimental data more accurate.

2. The reagent bottle for quantitatively measuring the solution described in the utility model is provided with a scale under the protrusion on the push rod, which can realize quick liquid taking, or actually measure according to actual needs.
