The Birth Background of Hand-held Sieve: From Tsinghua Laboratory to Classroom

As one of the top universities in China, Tsinghua University has been committed to scientific and technological innovation and popularization of educational resources. The launch of the Tsinghua handheld sieve is the product of this concept. At first, the device was mainly used for complex material analysis and research within universities and research institutes, but with changes in demand and technological advances, it has gradually been simplified and improved into a small tool that is now suitable for classroom teaching in primary and secondary schools.

Detailed explanation of the three-specification classification system: accurately meet different experimental requirements

In order to adapt to a variety of experimental scenarios, Tsinghua handheld screen has specially set up three standard aperture size options-three levels of large, medium and small. This design can not only help students better understand and master the concept of physical differences, but also greatly improve the efficiency of researchers. For example, in the process of mineral particle detection, the target component sample can be quickly screened by adjusting the corresponding mesh size.

Convenient operation design: let beginners get started easily

Considering that the user may be a child who is new to science or a researcher with a non-professional background, this handheld sieve takes a lot of thought in the details. For example, ergonomic principles are used to optimize the radian of the grip, so that you will not feel tired even if you use it for a long time. In addition, anti-skid lines are added to ensure that the firm grip will not fall off easily and cause damage risks, etc.

Dual Empowerment of Teaching and Scientific Research: Practical Application Case Sharing of Hand-held Sieve

In daily educational practice, many schools have begun to use such auxiliary teaching aids to carry out lively and interesting practical activity courses. An elementary school teacher gave feedback: "Since the introduction of this device, children have a deeper and more intuitive understanding of soil composition." At the other end of the spectrum, there is also a record of widespread use in high-end academia-a geological exploration team used this method to successfully identify the distribution characteristics of rock types in an unknown area.
