As one of the products developed by Tsinghua University, Tsinghua 81204 handheld screen stands out with its excellent functional design and humanized characteristics. The handheld sieve with three specifications of the sample design, suitable for a variety of particle size sample screening needs. Whether it is soil analysis in geological research or a teaching demonstration of seed size measurement in biology class, this handheld sieve can easily do the job.

In order to better meet the requirements of diverse working environments, Tsinghua 81204 hand-held screens provide flexible application solutions. For example, in elementary school science classes, students can use this device to intuitively understand the different morphological characteristics of natural substances; in a more professional chemistry laboratory, they can use it to complete quality control tests of fine powder materials. No matter what type of project it is used in, it can significantly improve work efficiency and reduce human error.

In addition to being functional, this handheld screen is also highly portable and easy to use. Its lightweight design makes it very convenient to carry, and it will not feel tired even if it is held for a long time. At the same time, it is equipped with a non-slip handle structure and a clear scale identification system to help users quickly find their own parameter setting position for operation adjustment. In addition, the high-precision mesh layout mode after repeated verification ensures that the samples selected each time meet the expected standard range.

Many teachers and researchers who have purchased and used them have given positive feedback. "Since the introduction of this small but powerful auxiliary device, our lectures have become much more lively and interesting." A senior science teacher said, "Students are now more willing to actively participate in practical activities to explore unknown knowledge points." In addition, many laboratory technicians said: "compared with the traditional method, the new filter greatly shortens the time consuming of the whole process and ensures a higher level of consistency of results." Through continuous improvement of innovative technical means combined with the advantages accumulated from practical experience, such a practical and reliable solution option has been created for consumers to choose and adopt!
