In addition to planning the layout in the laboratory decoration, the choice of furniture in the laboratory is also very important, laboratory fume hood is an indispensable part of laboratory work, they can not only protect the safety of experimenters, but also ensure the accuracy of experimental results. However, choosing the right lab fume hood is not an easy task. In the laboratory fume hood market, there are various types and specifications to choose from, and the needs of each laboratory may also be different. The editor of OneLink Laboratory will share with you how to choose the right laboratory fume hood in laboratory decoration.
1. Determine the type and purpose of the laboratory
Choosing the right lab fume hood requires a clear understanding of the type and purpose of the laboratory. Because different types of laboratories may require different kinds of fume hoods. For example, biological laboratories need biological safety cabinets to handle biological materials, while chemical laboratories need chemical fume hoods to handle hazardous chemicals. Therefore, before choosing a fume hood, it is necessary to fully understand the nature of the laboratory and the hazardous substances that may be involved in the experiment.
2. Security Requirements
Safety is the primary consideration when choosing a laboratory fume hood. Fume hoods should be designed and performed to protect experimenters from harmful gases, vapors and microorganisms. Specific safety requirements will vary depending on the nature of the laboratory, but the following should generally be considered:
Chemical fume hoods should have good gas emission capacity and the function of avoiding gas leakage.
Biosafety cabinets need to provide a biological barrier to prevent leakage of biological material and should comply with the appropriate biosafety level.
3. Ventilation performance
The performance of a fume hood is critical to the safety and comfort of the laboratory. Here are some considerations regarding ventilation performance:
Wind speed: The air speed inside the fume hood should be high enough to ensure that harmful gases and vapors are effectively discharged. Typically, the wind speed should be between 0.5 and 1.0 m/s.
Exhaust airflow: The exhaust airflow of the fume hood should match the amount of gas removed required for the experiment, usually measured by the number of air changes per hour.
Negative pressure control: Some experiments require negative pressure fume hoods to prevent the leakage of hazardous substances, which is especially important for handling highly hazardous chemicals.
4. Size and layout
Fume hoods should be sized and laid out to fit the space and workflow of the laboratory. Fume hoods should not obstruct access and operation within the laboratory. Therefore, when choosing a fume hood, it is necessary to fully consider the layout of the laboratory and the needs of the work area.
5. Energy efficiency
The energy efficiency of fume hoods has important implications for laboratory operating costs and environmental impact. Some fume hoods have adjustable air speed and automatic shut-off to reduce energy consumption. Choosing an energy-efficient fume hood can help reduce your lab's operating costs.
6. Material and construction quality
The materials and construction quality of the fume hood should meet applicable standards and be corrosion resistant and durable to suit the laboratory environment. Choosing a fume hood with good quality ensures its long-term reliability and performance.
7. Filters and accessories
Consider whether the fume hood requires additional filters and accessories to improve safety and performance. High-efficiency filters effectively capture harmful gases and particulate matter, and accessories such as UV lamps and sinks enhance the functionality of the fume hood.
When choosing the right laboratory fume hood, it is necessary to choose according to the type of different laboratories, safety requirements, ventilation performance, size and layout, energy efficiency, material quality and accessories, laboratory fume hood as an important experimental equipment in the laboratory, fume hood has a decisive role. By properly selecting and using laboratory fume hoods, the health of experimenters can be better protected, the accuracy of each experimental data can be ensured, and the overall efficiency of the laboratory can be improved.
