Precautions for using a ductless air ventilating cabinet

It can effectively adsorb chemical gases, and there are many precautions when using ductless fume hoods.

1. Reduce the scratch on the acrylic board.

2. When there is no experimental operation, the fume hood cannot be placed with chemical reagents. Always store the reagents in the medicine cabinet.

3, always pay attention to whether the filter is saturated, such as saturation and timely xi manufacturers to filter replacement, otherwise the filter once saturated and not replaced in time, will lose the role of protection.

4. Do not pile up debris in the fume hood to avoid uneven airflow and not reach the proper surface wind speed, resulting in a decrease in adsorption efficiency.

5. Do not move the fume hood when using the fume hood. Do not probe the head into the fume hood for experiment.

6. After the end of the experiment, the fume hood should be kept running for a period of time to ensure that the residual gas in the cabinet is completely absorbed by the filter.
