The following chart applies to all fritted glassware we sell (discs, fritted funnels, dispersion tubes etc.).
|Porosity||Pore Size (microns)||Typical uses and Notes|
|Fine (F)||4 - 5.5||Filtration of extremely fine precipitates, extraction. Not recommended for routine filtration as these run very slowly, are prone to clogging, and difficult to clean.|
|Medium (M)||10 - 16||Ideal for routine organic/inorganic extractions and filtrations and collection of crystalline materials.|
|Coarse (C)||40 - 60||Gas dispersion, gas washing, extractions, mercury filtration.|
|Extra Coarse (XC)||170 - 200||Support for other filter media, gas dispersion, gas washing|
