Product details
Ventilation reagent cabinetFor laboratories, it can add icing on the cake, improve the laboratory environment, and protect the occupational health and safety of laboratory personnel. We all know that a clean gas medicine cabinet has two main functions: firstly, it can filter harmful chemical gases emitted by chemicals inside the cabinet, and secondly, it can purify the laboratory air.
The performance of filters produced by different manufacturers varies greatly. Good manufacturers will choose an equilibrium point between adsorption and volatilization when producing filters. From a more professional perspective, the adsorption process of filters is a constantly balancing process. When reaching a certain point, the filter will release chemical molecules while adsorbing, which is similar to the process of dissolution and desorption.
So the adsorption capacity of the filter is a relative quantity, and its adsorption capacity depends on the "retention force" of the filter on chemical molecules. The role of the filter on chemical molecules is a combination of chemical and physical effects. Relatively speaking, chemical molecules with larger molecular weights have larger volumes, making it easier for the filter to have stronger "retention force".
What standards should be followed?
For the current standards for ductless fume hoods, different countries have different standards, and professionals in each country have different understandings of the ductless industry. The focus of the standards issued also varies. Simply put, which country's standard is strict.
What ventilation reagent cabinet is safe?
People with certain knowledge of chemistry know that the lifespan of a filter depends on the type of chemical it adsorbs and the amount of volatilization of the corresponding chemical, as well as the environment in which the filter is located, such as temperature and humidity. So it cannot be generalized that the lifespan of a filter is one year, which raises a crucial question of how to accurately determine the saturation time of the filter. If the filter is saturated and not detected or detected in a timely manner, it will immediately lead from safety to insecurity. Therefore, production-oriented enterprises must highlight online monitoring systems to accurately and timely inform customers.
