Importance and selection of medical equipment handle in biological laboratory freezer
In the field of biomedicine, preserving samples and reagents is one of the most important tasks. The equipment used to store these sensitive substances-frozen refrigerator, is the key facility to ensure the quality of samples. As one of the most frequently used components, the "handle" is small, but it plays a decisive role.
First, the function and importance of handle
1. Improve the convenience of operation: a high-quality handle can improve the speed and efficiency of the experimenter to open the door of the freezer, which is particularly important in an emergency; In addition, the reasonable handle design can also effectively reduce the risk of damage caused by excessive door opening and closing force.
2. Ensure safety: There are many potential hazards in the laboratory, such as virus or bacterial pollution, chemical leakage, etc. Therefore, strict safety measures must be taken when taking samples to prevent cross-infection and other problems. At this time, the reasonably designed handle can not only ensure that the staff are not injured, but also reduce the probability of other accidents;
3. Energy saving and environmental protection: When the refrigerator needs to be opened frequently for inspection or adding items, if the handle is not flexible enough, it will easily lead to the loss of cold air and increase energy consumption. Therefore, choosing the right handle is conducive to achieving the goal of energy saving and emission reduction.
Second, the selection and characteristics of handle materials
Products made of different materials can be selected according to different specific application scenarios:
1. Stainless steel:
This kind of product has high strength, strong corrosion resistance and easy cleaning and disinfection, and is suitable for use in the environment of frequent contact with water or multiple chemical components. But the price is relatively high.
2. Plastics:
Lightweight, low cost, good insulation performance and stable performance at room temperature; However, its heat resistance and mechanical strength are poor, and it may become brittle or even fracture if it is kept in a low temperature environment for a long time.
3. Alloys (such as aluminum alloy):
Combining the advantages of the above two materials, it has good strength and light weight, and can bear a large load without deformation; After special treatment, the surface can also achieve good anti-fouling and anti-corrosion effects.
Third, purchase suggestions
For most users, stainless steel is still the most recommended choice, especially in terms of professional requirements.
This is especially true in high places. Of course, we also need to consider budget constraints and personal preferences to make a final decision.
Need to pay attention to the following points:
Check whether it meets the relevant industry standards and safety certification marks;
Pay attention to the installation method, and try to choose a design scheme with simple structure, stability and reliability and convenient for later maintenance;
Select the appropriate size, shape and style according to the actual needs, so as to better fit the ergonomic principle and improve the work efficiency;
In a word, we need to comprehensively consider various factors and pay attention to details when choosing matching handles for freezers in biological laboratories, so as to find an ideal option that is both practical and beautiful.
