Summary of fogging causes and anti-fogging skills for goggles
Goggles are an eye protection device used to close or protect the eyes. They are mainly used to prevent infectious substances such as particles, water, chemicals, blood, and body fluids from invading the eyes. Practice has proved that wearing goggles is one of the important measures to directly prevent blood-borne occupational exposure and occupational infection.

How to determine the specifications and selection of experimental instruments
The experimental instrument configuration is to determine the specifications and selection of laboratory furniture on the basis of laboratory planning and design. Laboratory furniture is a new industry subdivided from the furniture industry, which tends to be standardized and specialized in the process of development. The experimental instrument configuration mainly includes layout, structure size, desktop selection, fume hood selection, experimental cabinet selection, safety facilities, etc.

What are the operational risks of experimental equipment?
The traceability of experimental instruments and equipment is one of the main means to ensure the accuracy of measurement. According to the requirements of laboratory qualification standards, instruments and equipment shall be verified or calibrated before use, and if necessary, interim verification shall be carried out between secondary verification or calibration to ensure the accuracy of data.

[Science Popularization] Experimental Instruments: A Complete Classification of Laboratory Glass Instruments
Due to the wide variety of glass instruments, a wide range of uses, different shapes, and experimental instruments in different professional fields use some special glass instruments, it is difficult to classify all glass instruments in detail. According to international standards, glass instruments and experimental instruments used in laboratories are generally divided into the following eight categories.

The role of goggles
Some friends who are usually interested in the military or like to play games may have seen goggles, especially the special forces in various game works. They are very handsome in training clothes and goggles and masks. Some friends may simply think that the main function of the goggles here is to look good. There are some features like night vision, but not really. These goggles also have an important role in protecting the user's eyes and avoiding eye injuries.

Goggles: the role and efficacy of goggles
Goggles can prevent the radiation source light from causing harm to the eyes, and to put it bluntly, goggles are a kind of filter. There are two types, one is absorption heat pump, one is double beam, and the previous one is used more. This kind of light source that can digest and absorb some light wavelengths and allow other light wavelengths to pass through, thus showing an inevitable hue, and the hue displayed is the through-light hue.

Goggles: the necessity of goggles maintenance
In the whole process of industrial production, both eyes are injured. Some non-hydrolytic radiation sources are injured in both eyes, so everyone should wear goggles to maintain everyone at work, and wear goggles suitable for their own face shape during work. The type of goggles you need depends on the theme activity you are practicing. You can not generally maintain your eyes from collision, debris or damage, here, goggles maintenance essential necessity!

Scientific and educational instruments: cleaning and cleanliness maintenance of electrostatic suit
Electrostatic suit are often used in some industries that require dust-free, such as bioengineering, pharmaceuticals, semiconductors and other businesses. The production sites of these companies need low dust in the production environment, but electrostatic suit are very easy to sweat, and sweat will reduce the characteristics of electrostatic suit, so it is necessary to clean it frequently.

Scientific and educational instruments: the importance of electrostatic suit for the protection of physical instruments
In winter, the damage of static electricity to physical instruments and equipment cannot be ignored. Why do physical instruments invest so much money in anti-static measures? Afraid of being hurt by static electricity! So how to avoid electrostatic damage to laboratory physical instruments? 1. How to generate static electricity? 2. Why are physical instruments prone to electrostatic breakdown? 3. What measures can we take to prevent static electricity?

Scientific and educational instruments: maintenance and maintenance of experimental instruments
The maintenance and maintenance of experimental instruments must implement the principle of "equal emphasis on maintenance and prevention", achieve regular maintenance, mandatory, and correctly handle the relationship between use, maintenance and repair. Do a good job in cleaning, lubricating, adjusting, tightening and anti-corrosion of experimental instruments and scientific and educational instruments, carry out daily maintenance and regular maintenance, and strictly abide by the cycle and inspection and maintenance items specified in the instruction manual.
