Description

A special reagent bottle for pH standard buffer solution

technical field

The utility model belongs to the field of experimental instruments, in particular to a special reagent bottle for a pH standard buffer solution.

Background technique

The pH meter is commonly used in the laboratory to measure the pH value of the solution. The pH meter needs to be calibrated with a standard buffer solution before use to ensure the accuracy of the measured pH value. When the pH meter is calibrated, the following situations are often encountered: on the one hand, due to The pH meter electrode cannot be fixed in the reagent bottle, so that when the standard buffer solution is shaken, the pH meter electrode is easy to touch the wall or the bottom of the bottle, causing damage to the glass beads of the pH meter electrode; on the other hand, the reagent bottle containing the pH standard buffer solution , usually a wide-mouth bottle, sealed with a plastic film after calibration. Due to the poor sealing of the plastic film, impurities will pollute the solution after entering, which will affect the use of the pH meter; therefore, in view of the above defects, a special reagent bottle for pH standard buffer solution that can fix the electrode of the pH meter and has a sealing effect is designed. .

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a practical special reagent bottle for pH standard buffer solution.

The technical scheme of the utility model is as follows: a special reagent bottle for pH standard buffer solution, mainly composed of a bottle body, a round hole, a fixing clip, a triangular baffle, a pH meter electrode, a bottle cap, a clip, and screws. A round hole is arranged on the top of the bottle body, and a triangular baffle is arranged inside the bottle body, and the electrode of the pH meter is inserted into the inside of the bottle body through the round hole, and the round hole and the bottle cap are connected by threads. A fixing clip is provided, and clips and screws are arranged on the fixing clip.

The diameter of the circular hole is slightly larger than the diameter of the electrode of the pH meter.

There are four triangular baffles inside the bottle, so that the standard buffer solution can be mixed evenly when shaking.

The beneficial effects of the utility model are: the utility model provides a special reagent bottle for pH standard buffer solution, which has a simple structure, can fix the electrode of the pH meter and has a good sealing effect, and the triangular baffle inside the bottle body can make the solution mix evenly.
