In the process of exploring the scientific world, every small tool may be an important bridge to inspire students' interests. Tsinghua University independent research and development of handheld screen-model 81204 is such a key role. This device is not only a good helper for elementary school students in science courses, but also an indispensable professional tool in the laboratory.

The biggest highlight of Tsinghua 81204 handheld screen is its unique triple specification design. Three different pore sizes can correspond to different ranges of particle sizes, thus realizing fine classification of the sample. Whether it is a soil sample or a chemical reagent mixture, this filter can complete the task quickly and accurately.

Why do educators trust this device so much? The answer lies in its minimalist design philosophy. Even students without any experience can master the correct use method in a short time. This is due to the designer's repeated consideration of every detail-lightweight ergonomic grip, non-slip surface and easy to remove and clean functional components.

From the basic primary school classroom teaching to the support field of high-level scientific research projects, we found that Tsinghua 81204 handheld sieve has a wide range of adaptability. For example, a professor in the Department of Geology of a famous university has successfully completed the research work of complex rock composition analysis with the help of this device. At the other end, there are rural school teachers who organize children to observe the phenomenon of seed separation to deepen their understanding of the laws of nature.

In addition to being purely a measuring instrument, it can also be one of the effective media to improve the quality of classroom interaction. Imagine this picture: students carefully compare their data results around the table, and enthusiastically discuss the reasons for the differences ...... Isn't such a lively learning atmosphere every teacher's dream?

Of course, behind any excellent product must be inseparable from solid and reliable material support and technology accumulation. This product is made of high-strength stainless steel material, in ensuring sufficient mechanical strength while taking into account the requirements of anti-corrosion performance; coupled with advanced processing technology to ensure that the various components closely cooperate with no error, so that the overall service life is greatly extended.

then which front-line users have given high evaluation on it? many famous teachers have praised: "compared with other similar products on the market, tsinghua brand has indeed performed better! "On the other hand, some ordinary parents left a message saying:" My children now take that small sieve to do all kinds of interesting experiments when they come home from school every day. Science is no longer out of reach ~ "

Looking forward to the future, with the continuous development and progress of science and technology and the increasingly obvious trend of interdisciplinary cross-integration, it is believed that practical and innovative teaching aids such as Tsinghua 81204 handheld screen will play a greater role in more unknown territories.
