What is a clean gas medicine storage cabinet?
The top of the clean gas medicine storage cabinet is equipped with a fan and a filtering device. The operation of the fan makes the cabinet form negative pressure, and air enters from the air inlet. Toxic gas and dusty air will be filtered by activated carbon filter and high efficiency particle filter, and the filtered clean air will return to the room. The clean gas medicine storage cabinet is used to protect the inhalation hazards brought by laboratory personnel when storing chemicals, and at the same time, it can circulate and filter indoor air for 24 hours.
Function of clean gas medicine storage cabinet
Wind speed regulation
Activated carbon filter screen filters volatile substances, and the lower the wind speed and air volume passing through the filter screen, the better the filtering effect.
Fan speed adjustment is applicable to:
Slow speed-the storage of chemicals is too large to be adsorbed under any circumstances. At this time, as long as the negative pressure in the cabinet is ensured, chemicals will not seep out, and the adsorption capacity of the filter screen is the strongest, achieving the best filtering effect. Medium speed is what respondents call the best wind speed. High speed, suitable for purifying laboratory air. At this time, there are very few volatile drugs in the cabinet and a small amount of volatiles in the laboratory air. Turning on the maximum wind speed is conducive to the rapid filtration of air, and very few chemicals are easily captured by the activated carbon filter, so it is understandable.
Temperature and humidity display
The reality of temperature and humidity is to determine whether the chemicals stored in the cabinet meet the requirements of chemical storage. Temperature and humidity are very important for the storage of chemicals, and some chemicals absorb moisture easily. If the humidity is too high, it will seriously affect the quality of chemicals and easily absorb moisture. At this time, the storekeeper should be reminded to dry the indoor environment to prevent the failure of chemicals. If the temperature is too high, a lot of chemicals will evaporate. Remind laboratory staff to reduce the temperature of storage room to reduce excessive volatilization of chemicals caused by excessive temperature, and remind users to reduce the temperature of laboratory, which can effectively increase the life of filter consumables. Although the temperature and humidity can't be changed, it can help the storer to visually see the environmental conditions of chemical reagent storage. How can it be said that the temperature and humidity display has no effect?
Clean air medicine storage cabinet can control wind speed, temperature and humidity, sunshine and other conditions. , will be very good to maintain the efficacy of drugs. The clean gas medicine storage cabinet can be used in various laboratories, environmental monitoring stations, food inspection offices and other places. , has a very wide range of uses and a very good experience, and has a good reputation in the market. If you don't have the opportunity to use it, it is also an excellent thing to know some different electrical appliances, so that you can help others in time when they need it.
