Whether demonstrating scientific principles in the classroom or carefully classifying samples in the laboratory, a professional sample sieving is an indispensable tool. Accurate and reliable separation results are critical especially in educational activities involving particle size measurement or research projects involving fine sample screening.

It is a product born under the background of such actual needs-the "81204 handheld screen" developed and launched by Tsinghua University. With its excellent functional performance and highly adaptable design features, it has quickly won the majority of teachers and students. And the favor and praise of scientific research workers.

As a professional equipment specially designed for primary school science and education and laboratory sample screening, "Tsinghua 81204 Handheld Sieve" has many outstanding highlights.
first of all, it has built-in three different aperture size settings (standard large, medium and small three gears respectively), which can flexibly switch corresponding modes according to specific task requirements so as to realize the purpose of accurately dividing the proportion of various material components. Secondly, the overall structure is compact, light and easy to carry and move, while ensuring the stability of long-term use, problems such as loosening are not easy to occur; moreover, it is specially made of high-quality stainless steel to ensure strong corrosion resistance, long service life, good sanitary conditions and high standards of food, medicine and other industries. it is no problem to use it within the scope of the restrictions stipulated in the high standards of the food and medicine industry.

in addition, another major feature of this product is that the operation is extremely simple and intuitive. even people who come into contact with similar devices for the first time can quickly familiarize themselves with the basic process steps and successfully complete the tasks set by the expected goals.

So for the first time people should be how to better realize the full potential of this product? Here are some very practical tips for everyone:
the first step is, of course, to read the instructions carefully to understand the meaning of various parameters and indicators and relevant precautions. Next, attention should be paid to adjusting the appropriate height and position relationship so that the materials to be processed can be evenly spread out to avoid error deviation caused by excessive local accumulation; the last point is to regularly check and maintain the tightening degree of screws in each connection part so as not to cause parts to fall off and lose due to vibration and other reasons. friends, remember to pay close attention to yo ~

Since its listing, the excellent quality of "Tsinghua 81204 Handheld Screen" has been widely recognized and supported by many users. Many school teachers said that after the introduction of this small and exquisite but powerful assistant in their natural science classes, students' interest in learning has increased significantly, and the understanding of abstract concepts has been deepened through specific observation and research on physical objects. Memory ability training has achieved remarkable results. In the eyes of experts and scholars in some professional fields, it is believed that such an economical and superior performance instrument and equipment can fully meet the test and analysis tasks required in most occasions in daily work.

Of course, we also need to pay attention to several important aspects to determine the most suitable model version before purchasing! The first is about the choice of capacity range, according to the comprehensive consideration of the types, volumes, quantities and other factors that they often deal with, it is necessary to decide whether it is suitable or not. Under the current conditions, continuous and stable operation will not easily occur. Under the current conditions, there will be no overflow and blockage, which will hinder the normal progress. The efficiency will drop too much, which will affect the accuracy of the final result. The judges must not carelessly deal with the past and make a hasty purchase decision!! Secondly, it is necessary to consider clearly the additional function options for special purposes in specific industries and understand clearly that there are no missing or forgotten important essential elements and characteristics. oh, only in this way can we really choose satisfactory good things and take them home to enjoy the convenience, speed and good time brought by science and technology, isn't it😊
