Quartz rod is a commonly used experimental tool, mainly used in preparation, heating, mixing, stirring and other experimental operations. The size and shape of quartz rod are two important factors of its working performance, which have a great influence on the experimental results. The following will be detailed from two aspects of quartz rod size and quartz rod shape.

First, the influence of quartz rod size on the effect

Quartz rod size refers to the length and diameter of the quartz rod. The size of the quartz rod has a direct impact on the experimental operation effect, and the following will be discussed in detail from the two aspects of length and diameter.

(1) The effect of length on the effect

Quartz rod length mainly affects the effect of mixing and mixing, generally speaking, the longer the length of the quartz rod, the greater the range of mixing and mixing. If you need to mix or stir a relatively large solution or reagent mixture, you should choose a longer length quartz rod to ensure adequate mixing. If you need to mix or stir a relatively small solution or reagent mixture, you can choose a quartz rod with a shorter length. The length of the quartz rod is also related to the depth of the bottle or container, and choosing a quartz rod that is suitable for the length can effectively reduce the difficulty of operation.

(2) The influence of diameter on the effect

The diameter of the quartz rod mainly affects the heating effect, and the thicker the diameter of the quartz rod, the better the heating effect. This is because the quartz rod with a larger diameter is relatively small compared to the quartz rod with a smaller diameter, under the same heating conditions, its surface area is relatively small, and the heat emitted is less, so the heating effect is relatively good. In addition, quartz rods with smaller diameters are prone to deformation during heating, and quartz rods with larger diameters are more heat-resistant.

In general, the selection of quartz rod length and diameter should be based on different experimental requirements. Before use, you should first understand the size of the container and the operating material, and accurately select the length and diameter of the quartz rod to ensure good results.

Second, the influence of quartz rod shape on the effect

The shape of quartz rod mainly affects the mixing, stirring and moving effect during the experimental operation. The influence of quartz rod shape on experimental results will be elaborated from two aspects of rod shape and end shape.

(1) The influence of rod shape on the effect

There are two common quartz rod shapes: round rod and hexagonal rod. Hexagonal rods have more edges, so it is easier to grip objects during mixing, stirring, and moving, and the mixing effect is better. The round rod is smoother in operation, it is not easy to grasp the object, and the operation is relatively easy. Therefore, when carrying out special mixing and stirring experiments, hexagonal rods should be selected to obtain better results, and circular rods should be selected when carrying out smooth operations.

(2) The influence of the end shape on the effect

The end shape of the quartz rod is also an important factor affecting the experimental operation effect. The end shapes of quartz rods are mainly notched, round and conical. These three shapes of quartz rods are used differently and each has its own unique advantages.

The notched quartz rod end is often used to mix two different volumes of solution or reagent mixtures, and its end shape allows the two solutions to be better mixed and does not separate the two solutions.

The round quartz rod end is suitable for mixing reagent mixtures with higher consistency, it will dig the reagent mixture outward, and at the same time stir the mixture evenly to achieve the mixing effect.

The tapered quartz rod end is suitable for filling samples because the tapered end can better fit the material into a smaller bottleneck. In addition, it can be used to mix solid samples and grind solid samples fine.

In SUMMARY:

The size and shape of the quartz rod have a direct impact on the experimental effect, so it is necessary to choose a suitable quartz rod in different experimental operations. If you do not understand or choose improperly, it may have different degrees of influence on the experimental operation and affect the accuracy of the experimental data. When using quartz rods, it is also necessary to pay attention to material selection, cleaning and maintenance to ensure that it can play a good working performance for a long time.
