Detailed Description
This grade has finer particle retention than Ahlstrom 601 but with slightly lower filtration speed. Ahlstrom 642 also has higher absorption than Ahlstrom 601. It is used in general laboratory applications to retain particles above 2 µm in size. Ahlstrom 642 is also found in agricultural and environmental laboratories for plant growth trials, soil testing, and air analysis for monitoring specific contaminants and in the filtration of organic and sulfide precipitates
