Make the classroom easier and more efficient

In the science experiment class of primary and secondary schools, how to make students grasp the basic knowledge of material separation intuitively? The traditional teaching method is often difficult to stimulate students' sense of actual participation. And Tsinghua 81204 hand-held sieve is an ideal teaching aid for this purpose.

It is equipped with three precise aperture designs-fine, medium and coarse, and can complete a variety of tasks from sand and gravel classification to powder screening. This not only visualizes abstract concepts, but also builds a bridge between textbooks and the real world for students, making the seemingly complex particle classification process accessible, easy to understand and operate.

Teaching considerations behind precision technology

Tsinghua brand always pay attention to the practicality and comfort of products, and strive for perfection in details. Each structure of this handheld screen is the result of careful polishing to better serve the classroom teaching environment.

The angle of the screen is set at an inclination that is most suitable for observation and use; the handle part is designed with a non-slip treatment, so that even younger students can hold it firmly and not easily fall off. Such ergonomic considerations greatly enhance the overall sense of experience, even if it takes a long time to repeat the action will hardly feel tired.

Practical performance testing in the lab

When it comes to educational equipment, "stability" and "durability" are often one of the key factors in determining procurement decisions. Tsinghua 81204 model of hand-held sieve because of its excellent quality performance has won the trust of many schools.

Whether it is the challenge of frequent use or the friction loss caused by a variety of complex samples (such as soil, slag or even food ingredients), this tool can maintain good working condition and ensure a high degree of consistency and reliability of the data measured every time. This means that teachers can put them into daily teaching activities with more confidence, and truly achieve "one investment, long-term benefit '.

Teaching aids to stimulate children's interest in inquiry

Every child has a curiosity to explore the unknown. The key lies in whether we give them the right way to express this enthusiasm. Tsinghua hand-held sieve is a kind of learning aid vessel that can give full play to this nature.

it is highly interactive and easy to operate, which is very suitable for guiding children to ask questions and cultivate independent thinking ability and problem-solving methodological consciousness in the process of finding answers through personal attempts. For example, why do balls of the same size fall through different grids? Such open-ended questions can easily arouse children's strong interest and further explore the relevant principles.

Flexible configuration for multiple disciplines

Although it was originally developed for basic science courses, the application scope of Tsinghua 81204-type sample screening is far more than this limitation.

whether it is the preliminary finishing and processing of rock debris in geographical subjects, or the identification and judgment of seed size differences under agronomic projects, even the research on the distribution of microbial growth media particles in the field of biology can achieve good results with the help of this device. Therefore, it can be said that it is a rare multi-functional demonstration props in modern campus.

Eco-friendly materials shape a green future

As the public's growing awareness of environmental protection continues to increase, the concept of "sustainable development" has penetrated into various industries, of course, including our next generation growth space-inside and outside the classroom.

Tsinghua series of scientific research equipment manufacturers responded positively to the call to use high quality recycled plastics as the main manufacturing materials to produce these new models of equipment. These new materials not only ensure the strength and flexibility, but also do not contain any chemical components that may endanger health problems.

• Safe and reliable-eliminate the risk of harmful substances release
• Durable-less replacement frequency reduces resource consumption
• Friendly experience-mild and soft physical properties, suitable for long-term direct contact with people, especially those with sensitive skin

It can be seen that choosing such a product with dual advantages of both functionality and social responsibility is undoubtedly a manifestation of being responsible for the entire planet.
