Description

Technical Field

[0001] The utility model relates to a stirrer used in cooperation with a pH meter in a laboratory, belonging to the technical field related to liquid preparation and pH adjustment experiments in the laboratory, especially in biochemistry experiments. Background Technique

[0002] During the process of liquid preparation in the laboratory, it is usually necessary to add acid or alkali to adjust the pH of liquid reagents, that is, a pH meter and a stirrer are needed to be used simultaneously. However, during actual operation, the stirrer is extremely likely to collide with the pH meter probe, and even damage the pH meter probe, seriously affecting the stirring efficiency. The utility model designs a stirrer that can be used in cooperation with a pH meter, which contains a placement hole for the pH meter probe, and can achieve the effect of not affecting the stirring quality during pH detection and improving the experimental efficiency. Summary of the Invention

[0003] The purpose of the utility model is to provide a stirrer used in cooperation with a pH meter to solve the technical problems that when adjusting the pH value of a solution, the stirring rod often touches the pH meter, affecting the stirring efficiency, and easily damaging the pH meter probe, causing unnecessary losses.

[0004] To achieve the above purpose, the specific technical solution of a stirrer used in cooperation with a pH meter of the utility model is as follows:

[0005] A stirrer used in cooperation with a pH meter, the main body includes a through hole for placing the pH meter probe, a stirring paddle, and a stirrer base;

[0006] Furthermore, the through hole for placing the pH meter probe is provided with a pH meter probe wiring fixer, which can fix the penetration height of the pH meter socket;

[0007] Furthermore, the stirring paddle includes 2 three-blade paddles, and the height can be adjusted so that the paddle blades are immersed below the liquid level to be stirred;

[0008] Furthermore, the side of the stirring paddle is provided with a stirring handle, and the cross bar of the handle has a telescopic function, which is convenient for manual stirring operation;

[0009] Furthermore, the stirrer is made of heat-resistant plastic material, which is easy to clean and dry, and has a certain tolerance to acids and alkalis.

[0010] A stirrer used in cooperation with a pH meter of the utility model has the following advantages:

[0011] The stirrer provided by the utility model can avoid the collision between the pH meter probe and the stirrer during the stirring process of pH adjustment, improve the experimental efficiency, and facilitate the operation of conventional experiments. Description of the Drawings

[0012] Figure 1It is a schematic structural diagram of a stirrer used in conjunction with a pH meter.

[0013] In the figure, 1 is the stirrer handle, 2 is the pH meter probe wiring fixer, 3 is the stirrer handle telescopic rod, 4 is the through hole for placing the pH meter probe, 5 is the three-blade paddle of the stirrer, and 6 is the stirrer base. Detailed implementation manners

[0014] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a stirrer used in conjunction with a pH meter of the present utility model with reference to the accompanying drawings.

[0015] Example 1: Use of the stirrer when stirring alone

[0016] Place the stirrer in a container, adjust the height of the stirring paddle so that it is below the liquid level, and operate the stirring rod with one hand to stir the liquid.

[0017] Example 2: Use of the stirrer when used in conjunction with a pH meter

[0018] When preparing a solution and adjusting the pH value is required, insert the pH probe of the pH meter into the central through hole of the stirrer, use the pH meter probe wiring fixer to fix the pH probe wiring, then place the stirrer together with the pH probe in a container, adjust the height of the stirring paddle so that it is below the liquid level, operate the stirring rod with one hand to stir the liquid, and at the same time use the pH meter to detect the pH value.

[0019] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present utility model still fall within the protection scope of the present utility model.
