An important accessory in biological laboratory-the handle of freezer
With the progress of science and technology and the development of medical industry, more and more precision equipment has been applied to biological research. Among them, the biological laboratory freezer, as an important tool for storing reagents and samples, plays an important role in the experimental process. The handle of the freezer is the part that users contact most.
1. The importance of the handle
In daily work, the experimenter needs to open and close the freezer frequently to take samples or store samples, so the handle of the freezer directly affects the work efficiency. A reasonably designed and easy-to-operate handle can help the experimenter to finish the work more efficiently and conveniently; On the contrary, it may increase the workload of staff and even bring unnecessary security risks.
In addition, because the temperature inside the freezer is usually very low (below 20℃), if you directly touch the cold door panel or glass window, it will lead to skin frostbite and other problems. At this time, a high-quality handle with good heat insulation performance is particularly important.
2. Material selection
Common materials on the market include plastic, metal and rubber, etc.
(1) Plastic: light weight, low cost and good insulation and corrosion resistance;
(2) Metal (such as stainless steel): high strength, good stability, but strong thermal conductivity can easily lead to user injury;
(3) Rubber: soft and comfortable, with good hand feeling and good anti-slip effect.
You can choose the product type that suits you according to the use environment and different needs.
3. Design concept
In addition to the above-mentioned factors, ergonomic principles should also be taken into account in manufacturing to ensure that long-term use will not cause harm to the body. For example, the size is designed to be moderate and an arc curve is added to reduce the pressure on the palm; It is very important to make the surface smooth and delicate by special treatment to avoid scratching fingers and other small details.
4. Cleaning and maintenance
In order to ensure the overall health and safety level, it is also one of the essential steps to clean and disinfect the surface regularly:
(1) Use a soft cloth to wipe with appropriate amount of water to remove dust stains;
(2) Avoid using irritating chemical solvents to avoid damaging the properties of the material itself.
Through this simple maintenance method, the service life can be extended and the best performance can be achieved.
To sum up, although seemingly simple and unremarkable, it occupies an extremely important position in the whole system operation process. Only when every link is done to the extreme can we really improve the research efficiency of the whole team and lay a solid foundation for subsequent breakthroughs!
