To promote the spirit of scientists and stimulate the innovation vitality of the whole society, on May 24th, Vic science popularization volunteers entered the campus and prepared a unique science popularization activity for students. The content of this science popularization activity is rich and colorful. Through exhibitions, interactions, experiences, lectures, and other forms, we have brought a science popularization feast to children. In the coming time, our science popularization activity will have more exciting content waiting for everyone to explore. I hope everyone can gain full joy in this feast of knowledge and become little experts in life! I also wish the children a happy International Children's Day in advance!

To strengthen the construction of science popularization capacity, deeply implement the national science literacy action, vigorously promote the spirit of scientists, and establish a campus culture of loving and advocating science. Recently, the Vic Science Spring Bud Youth Science Popularization Volunteer Service Team entered the campus and conducted a series of science popularization propaganda to students.

Deepen the implementation of the National Science and Technology Quality Action and vigorously promote the spirit of scientists. On May 28th, on the occasion of the National Science and Technology Activity Week and Children's Day, Vic Science, Dake Education, the Second Party Branch of the School of Foreign Languages at Henan Institute of Technology and the Party Branch of Henan Dake Teaching Instrument Co., Ltd. jointly held a parent-child activity with the theme of "Happy Children's Day, Embracing Science”, We sincerely invite the children of our company's employees and the children of teachers from the Henan Institute of Technology to participate, and have the honor of inviting two leaders from the Municipal Association for Science and Technology and teachers from the Henan Institute of Technology to explore the mysteries of biological science together.

The use of biological specimens is diverse and plays an important role in scientific research and biological teaching. In addition, they are also of great value in drawing, exhibition, viewing, etc. For scientific research, biological specimens can provide direct, reliable, accurate and intuitive objects and data for scientific research, which is of great significance for studying the life, growth and development laws of animals and plants. For example, when plant taxonomists systematically classify various plants, they must take plant specimens as the main basis, analyze the differences of research objects in root, stem, leaf, flower, fruit, seed and other aspects through plant standards, so as to correctly judge their characteristics, so as to accurately identify each plant.

A frozen slicer refers to an instrument that can rapidly produce arrangement slices for observation by achieving a certain hardness at low temperatures. The frozen slicer consists of slicing equipment and a refrigeration system. A complete frozen slicing system is generally composed of a host (freezer box, sample head, quick freezing table, etc.), a knife holder, and blades; Some frozen slicers also have vacuum equipment, which is used to suck up the waste inside the machine and assist in flattening the slices. The frozen slicer is an equipment produced in Germany, with a slicing scale of 1-500 μ m. The function of the frozen slicer is that it is suitable for directly slicing arranged in a frozen state.In the frozen slicing machine, the embedded sections are arranged to be frozen until they are firm, and before freezing, no chemical treatment or heating process is arranged, greatly reducing the production time. Meanwhile, due to the fact that the arrangement does not require processes such as dehydration, visualization, and waxing, it is more suitable for fat, nerve arrangement, and some chemical preparation methods, and is widely used as a rapid sectioning method in clinical diagnosis.The fundamental operation of a frozen slicer:1. Turn on the power 2 hours before use and set the temperature to -25 ℃;2. Place a specimen of appropriate size and thickness on a mushroom shaped cup, add frozen wax, and clip it into the fixed slot of the slicer;3. Prepare the glass slides, select the thickness of the slices, and swing the handle to make the slices;4. Carefully adhere the sliced pieces onto the glass sheet;5. After use, close the power supply, clean the chamber and wipe off any moisture, and keep a record of the use.6. To allow water vapor to evaporate, please do not immediately close the sliding door of the slicer cover. It should be closed every other day. If you need specific instructions, please borrow the instruction manual.The above content is presented to you by the supplier of fully automatic paraffin slicer equipment.

Freezing slicer and paraffin slicer are different pathological instruments, so what is the difference between freezing slicer and paraffin slicer? The manufacturer of the fully automatic paraffin slicer will take you to take a look togetherThe frozen slicer, also known as the frozen slicer, is mainly used for rapid diagnosis, such as intraoperative rapid pathological sectioning, pharmaceutical research and development, inspection and quarantine, etc. After the sample is delivered to the pathology department or laboratory, the staff directly use a frozen slicer to quickly complete the embedding and freezing sectioning work, and then complete the sectioning through a series of operations such as staining, observe under a microscope, and obtain a report.Before the paraffin slicer works, it is necessary to use a dehydrator to dehydrate and transparent the sample, and then use a paraffin embedding machine for embedding before starting the slicing operation.The main differences between the two are as follows:1. Time requirement: The use of a frozen slicer requires speed, while a paraffin slicer has relatively lenient time requirements. Frozen sections generally require a report to be produced within 30 minutes, while paraffin sections typically take around 3-7 days to produce a report.2. Sample requirements: The use of a frozen slicer has strict requirements for samples, but a paraffin slicer has no specific requirements for samples. Almost all biological samples can be operated using a paraffin slicer.3. Slice preservation time: The tissue structure of the slices made by the paraffin slicer is well preserved, able to cut continuous thin sections, with clear tissue structure, accurate antigen localization, and can be stored for a long time. The slices made by the frozen slicer can preserve the immune activity of various antigens relatively well, and can only be stored at low temperatures for a short period of time.4: Performance parameter requirements: Two products, two performance parameter requirements.
