Talking about the handle of ventilation equipment in biological laboratory
With the progress of science and technology and the improvement of experimental technology, the requirements for experimental environment are becoming stricter. Especially in the biological laboratory, good ventilation is one of the important links to ensure the safety and health of scientific researchers. As a key component connecting people and equipment-the handle of ventilation equipment, its design and performance are self-evident.
A, the role of ventilation equipment handle
In the daily operation process, experimenters need to frequently switch ventilation equipment such as fume hoods. At this time, the handle of ventilation equipment has become an important carrier to realize this function. An excellent handle of ventilation equipment should have the following characteristics:
1. Convenient operation: when in use, it feels comfortable and easy to hold, so that users can easily complete the switching action;
2. Corrosion resistance and wear resistance: Because there are a lot of chemicals in the laboratory environment, it is required that the handle material must have strong corrosion resistance and wear resistance to prolong the service life and ensure safe and stable operation;
3. Safety: Avoid accidents caused by hand slipping.
Second, choose the right material to make the handle.
At present, several common handle materials on the market include metal (such as stainless steel), plastic and rubber. They have their own advantages and disadvantages, and should be selected flexibly according to the specific situation in practical application:
Stainless steel: this material is usually used to manufacture high-quality and high-precision handle products. It not only has beautiful appearance, but also has high strength and durability, and is not easy to be deformed and damaged. But the price is relatively high.
Plastic or ABS engineering plastic: This kind of material has low cost and simple processing technology, and is suitable for mass production. At the same time, it also has certain insulation performance and is suitable for anti-static places; However, due to insufficient hardness, deformation may occur after long-term compression, which will affect the service life.
Rubber/silica gel: these two materials have moderate softness and good touch, which can effectively reduce the hand fatigue caused by long-term grasping; Moreover, they all have good sealing and waterproof ability, and are especially suitable for places with heavy moisture or frequent cleaning and disinfection; However, they are easily contaminated with dust and dirt, and they are less resistant to the influence of high temperature environment.
Third, the conclusion
In a word, when purchasing the handle of ventilation equipment, we must consider all factors comprehensively, not only the practical value but also the aesthetic degree. Only in this way can we really achieve both good and practical purposes!
The above is the introduction about the handle of ventilation equipment in biological laboratory, hoping to help you!
