QUAL-20UM Filter Paper has a very fast filtration speed (pore size: 20-25μm), can trap coarse particles and colloidal deep substances (such as iron hydroxide and aluminum hydroxide) which is suitable for rapid biological or organic extracts in daily analysis filters. When monitoring high-velocity air pollution, this qualitative filter paper can also be used (if it is not necessary to trap fine particles). QUAL-20UM is suitable for rapid filtration of conventional biological liquid and organic leach in the analysis. In air pollution monitoring, a high velocity is only required but the collection of fine particles is not strict.
