HAWACH glass fiber extraction thimbles can be applied in Soxhlet extraction and stationary pollution source detection. It is used when cellulose extraction thimble with a temperature higher than 120℃ and strong acid cannot be used. It is also used for detection of fixed pollution sources: flue gas, soot; such as cadmium, nickel, tin, fluoride, etc. of fixed pollution sources in the atmosphere, lead, asphalt smoke, sulfuric acid mist, etc., ambient air and exhaust gas arsenic, dioxin, etc.
The glass microfiber extraction thimbles are often used in the gravimetric method at high temperatures; Acid gas gravimetric method; Extraction methods commonly used in biochemical analysis.
Notes about the application
But for the fixed pollution sources in the atmosphere, you also need to understand the properties of dust: ordinary dust, ultra-fine dust, wet dust or flammable and explosive dust. The filter material is set, then you must decide the number of folds or effective filtering area of your filter cartridge It will determine whether the air volume of the extraction thimble matches the air volume of the entire dust collector, otherwise, either the dust collector’s dust removal effect is not good or the extraction thimbles’ service life is short.
How to use it
After the extraction thimble is numbered, put it in a drying box and dry it at 150℃ for 30 minutes. Then take it out and cool it in a dryer for 30 minutes. After taking out, weigh it and use it. After sampling, it was placed in a 100℃oven for 30 minutes, and then cooled in a dryer for 30 minutes and weighed.
