Features of Tsinghua 81204 Hand-held Sieve

tsinghua 81204 handheld sieve is a specially designed for primary school science and education experiment design of multi-specification efficient sample sieve. Its uniqueness lies in its multi-specification design, portability and high precision. Compared with other similar products on the market, Tsinghua 81204 handheld screen is not only easy to operate, but also can provide accurate and reliable data in a variety of experiments. Ideal for educational institutions and home labs, this handheld sieve meets different experimental needs and helps teachers and students better conduct scientific experiments.

Multi-specification design meets different experimental requirements

Tsinghua 81204 handheld screen is equipped with three specifications of the screen, respectively, 1mm, 2mm and 3mm. These different specifications can meet a variety of experimental needs. For example, in biology class, a 1mm screen can be used to screen seeds to help students observe seeds of different sizes. In geography class, a 2mm screen can be used for soil analysis to help students understand the composition of soil. In chemistry class, a 3mm screen can be used for substance separation to help students study the physical properties of different substances. Through these specific application examples, we can see the efficient performance of Tsinghua 81204 handheld screen in the experiment.

Easy to operate, suitable for primary school students

Tsinghua 81204 hand-held screen is very easy to operate, suitable for primary school students. First of all, the assembly process is very simple, just insert the screen into the main part. Next, the appropriate screen specifications can be selected according to the experimental requirements. Then, spread the sample evenly on the screen and gently shake it by hand to start the sieving process. The whole operation process is intuitive and clear, even inexperienced students can quickly master. In order to make it easier for teachers and students to get started, we also provide detailed illustrations and video tutorials to help everyone easily complete the experimental tasks.

High precision ensures experimental accuracy

Tsinghua 81204 handheld screen in the experiment accuracy is very high, can ensure the accuracy of the experimental data. Through practical cases and user feedback, we can see the important role of this handheld sieve in experimental data collection and analysis. For example, in a soil analysis experiment, the students used a 2mm screen to screen the soil samples. The results showed that the soil particles after screening were evenly distributed and there were no large clumps, which provided a reliable basis for subsequent experimental analysis. Through scientific data and experimental results, it is not difficult for us to see the high precision and reliability of the Tsinghua 81204 handheld screen.

Wide range of application scenarios

Tsinghua 81204 handheld screen has a wide range of application scenarios in primary school science curriculum. In addition to the biology, geography and chemistry classes mentioned earlier, it can also be used for material classification experiments in physics classes and water quality testing experiments in environmental science classes. Through specific teaching cases, we can see the application value of Tsinghua 81204 handheld screen in different disciplines. For example, in a physics class, students used a 3mm screen to classify different materials and understand the physical properties and uses of the materials. In another environmental science class, the students used a 1mm screen to filter river water samples and detect the content of suspended solids in the water. These rich application scenarios show the important position of Tsinghua 81204 handheld screen in science and education experiments.

Maintenance Guide

In order to ensure that Tsinghua 81204 hand-held screens remain in good working condition for a long time, we need to clean, store and maintain them regularly. When cleaning, you can wipe the main body part and the screen with a soft cloth to avoid using corrosive cleaning agents. When storing, it should be placed in a dry and ventilated place, avoiding humidity and high temperature. In addition, the residue on the screen should be cleared in time after each use, so as not to affect the next use. Through these simple maintenance methods, we can ensure that the Tsinghua 81204 handheld screen is always in the best condition.
