Disadvantages of vertical flow benches
Disadvantages of vertical flow benches(I) High price and maintenance costAs high-tech equipment, vertical flow benches are usually expensive. For some small enterprises and laboratories, it may be difficult to afford their high prices. For example, the simple vertical flow clean bench FFU clean bench stainless steel frame and tempered glass around the tabletop, the price ranges from several hundred yuan to nearly a thousand yuan, while some high-end vertical flow benches may be more expensive. In addition, the filters and fans of the vertical flow bench need to be replaced and maintained regularly, and the maintenance cost is high. The filter is a key component of the vertical flow bench. To ensure the environmental cleanliness and filtration efficiency of the clean bench, the filter needs to be replaced regularly. According to the frequency of use and the corresponding conditions of the working environment, the filter is usually replaced every 6 months to 1 year. Moreover, maintenance work requires professional personnel to operate and maintain, which also increases the cost. Taking the three-person vertical flow clean bench as an example, its maintenance requires a professional technical team, including development and scientific research, production management, equipment engineers, and other personnel to ensure the normal operation of the equipment. (II) Large footprint Vertical flow benches usually require a large space for installation and operation. This may cause some trouble for some laboratories with limited space. The structural design of the vertical flow workbench determines that it requires a certain amount of space to ensure the circulation and filtering effect of the air. For example, in some small laboratories, the space is limited, and the installation of a vertical flow workbench may take up a lot of space, affecting the placement of other equipment and the convenience of experimental operations. In summary, although the vertical flow workbench has the advantages of high-efficiency filtration performance, convenient operation, energy-saving and environmental protection characteristics, and stable reliability, it also has shortcomings such as high price and maintenance costs and large floor space. When selecting and using a vertical flow workbench, it is necessary to weigh and consider it according to the actual situation to give full play to its advantages while minimizing the impact of its shortcomings. |
