Exhaust reagent cabinetIt is an important part of laboratory design, and in order to prevent laboratory staff from inhaling or swallowing toxic, pathogenic, or unknown chemicals and organisms, the laboratory should maintain good ventilation. Below we will explain in detail for youExhaust reagent cabinetPurchase precautions.
The good performance of a fume hood mainly depends on the speed at which air passes through the hood. Therefore, when selecting a fume hood, the main focus should be on these three aspects:
1. Determine the purchase size
The large size of the fume hood causes waste, and the small size can also affect its use. Therefore, before purchasing a clean air fume hood, we need to choose the appropriate external dimensions based on the laboratory conditions and the chemicals, containers, instruments, etc. required for the experiment.
Generally speaking, the internal dimensions of a clean air fume hood are almost the same as the external dimensions. For example, if a typical outdoor fume hood uses 1.8 meters, purchasing 1.6 meters of fume hood can meet the internal usage area, which can save laboratory space and equipment procurement costs.
2. Select filter
Firstly, it is necessary to choose a manufacturer with good qualifications. The core technology of a fume hood is the adsorption efficiency and monitoring system of the filtration system, which is a basic and core requirement of the product. Therefore, the quality of the filter directly affects the subsequent use of the clean air fume hood and may even affect the health of the operator. Therefore, when choosing a fume hood, it is necessary to first understand whether the manufacturer has the relevant qualifications.
3. Choose a fume hood with automatic detection function
For new air purifying fume hoods, products from various manufacturers can adsorb varying amounts of gas (dust) to a greater or lesser extent. However, the lifespan of the new filter and whether the product's timeliness can be controlled within one year or longer require real-time monitoring to determine clearly.
