Analysis on the handle of light box in plant biology laboratory
I. Preface
In modern biological experiments, the plant biology laboratory is one of the indispensable scientific research places. In order to better simulate the natural lighting conditions and observe the growth process of plants, light box equipment is widely used in plant biology laboratories. As a key component to open and close these devices, the handle of the light box is particularly important.
Second, the design characteristics and functional requirements of the light box handle
1. Design features
(1) High safety: various types of plant samples, reagents and other items are usually stored in the lighting box, so it is necessary to ensure that the handle has good mechanical strength and durability to avoid damage or falling off due to accidents;
(2) Easy to clean and maintain: due to frequent contact with hand skin surface residues such as grease and sweat, the handle material should be easy to clean and disinfect;
(3) Convenient and comfortable operation: Good ergonomic design principles can effectively reduce the fatigue of users when they operate for a long time.
2. Functional requirements
When opening/closing the door body, it can provide enough friction to prevent slipping; Convenient for disassembly and replacement, convenient for daily maintenance; In addition, its waterproof and moisture-proof performance should be considered to avoid corrosion and rust caused by long-term exposure to humid environment and affect its service life.
Third, the application example analysis of light box handle
At present, several common materials on the market and their advantages and disadvantages are compared as follows:
1. Plastics
Advantages: low cost, portability, no electricity and no heat conduction;
Disadvantages: low strength and easy aging and deformation.
2. Aluminum alloy profiles
Advantages: small specific gravity, light weight, good hardness, strong wear resistance and corrosion resistance;
Disadvantages: the relative price is higher.
3. Stainless steel products
Advantages: stable physical and chemical properties, less interference from external factors, less oxidation and discoloration, etc.
Disadvantages: the processing is difficult and the cost is high.
IV. Conclusion
To sum up, the handle of the light box plays a vital role although it seems insignificant. Only by reasonably selecting materials, paying attention to humanized design concept and combining with actual needs can we meet the requirements and standards of modern scientific research for facilities. With the progress and development of technology in the future, I believe there will be more innovative products to solve the current problems.
