Scientific research is inseparable from the delicate operation, and a suitable tool is often one of the key to success. Today we want to recommend to you is carefully built by Tsinghua University 81204 handheld sieve , which is a functional equipment designed for science education and laboratory.
New partners in exploring science: understanding the design concept and background story of the handheld sieve
This hand-held screen comes from the hands of the Tsinghua University team, which embodies many years of scientific research experience and accumulated efforts of educational resources. Designers are well aware that in the process of scientific learning and research, sample classification is a basic but extremely important work. Therefore, they focused on developing a simple, easy-to-use manual screening tool with high accuracy.
through continuous testing and improvement, and finally the birth of this set of three specifications in a handheld sieve. Each layer of screen is precision processed to ensure accurate particle classification, helping users to easily complete the separation of materials in various particle size ranges.

Analysis of triple screening function: how to separate accurately according to different particle sizes
the hand-held sieve is equipped with three layers of different mesh sizes (φ0.2mm, φ0.5mm and φ1.0mm respectively), which can meet the processing needs of various particle samples from small to large. When it is necessary to further distinguish the mixed powder or granular material, simply pour the material to be tested into the top inlet and shake the device gently by hand, and the components of different diameter levels will fall into the corresponding collection area step by step.

From the classroom to the laboratory: a case study of the practical application of hand-held screens in multiple scenarios
whether it is to explain the principle of soil composition in popular science courses in primary schools or to measure the distribution ratio of reaction products in chemical laboratories, this small and lightweight hand-held screen can play an important role. For example, in the field of geology, it can be used to quickly determine the quality level of gravel; and in the food industry, it is suitable for detecting whether the uniformity of flour particles is up to standard.
Materials and Processes: Why It's Important to Choose High-Quality Stainless Steel Manufacturing
In order to ensure durability and stability for long-term use, all parts are made of high-grade medical grade stainless steel. This material has strong corrosion resistance and smooth surface characteristics, which can not only reduce friction to improve work efficiency, but also facilitate cleaning and maintenance to extend service life.

Efficiency Improvement Guide: Tips for Easier and Faster Operation
although this handheld screen is very easy to use, we have compiled some practical suggestions to help you get twice the result with half the effort:
-confirm that the layers are installed in place in the correct order before use
-try to control the amplitude smoothly under the condition of high vibration frequency to avoid splashing phenomenon
-regularly check the connection parts for signs of looseness and adjust the fastener status in time
Selected user feedback: listen to the practical experience of researchers and teachers
"As a high school physics teacher, I often need to use auxiliary teaching aids like this to conduct demonstration activities. Since the introduction of the Tsinghua version of the handheld sieve, the students' interest in learning has improved a lot! "
" I also tried other brands and models of products during my duties as a quality inspection engineer in a pharmaceutical factory and found that it did perform well, especially for continuous operation mode in batch inspection situations... "
In short, this 81204 multifunctional hand-held screen created by Tsinghua University's ingenuity not only meets the professional standards required for daily teaching, but also shows excellent and reliable quality performance in complex environments.
